Hongming Wang cfa2fc3d6e docs: update clone URLs after molecule-core repo split (quickstart + self-hosting) 2026-05-01 19:24:55 -07:00
Hongming Wang e0910a1734 Merge pull request #114 from Molecule-AI/docs/fix-staging-dns-architecture
docs(arch): correct staging DNS — per-tenant CNAME, no wildcard
2026-05-01 19:21:42 -07:00
Hongming Wang c93388441d docs(arch): rewrite staging DNS section (per-tenant CNAME, not wildcard)
The "Architecture" diagram and section 5 ("Cloudflare: staging
subdomain") both implied that `*.staging.moleculesai.app` is a wildcard
DNS record. It is not. The control plane writes a per-tenant CNAME at
provision time (see `internal/provisioner/ec2.go` ->
`Tunnel.CreateTunnelDNS`), and unknown slugs correctly return NXDOMAIN.

This rewrite:
- Replaces `*.staging.moleculesai.app` / `*.moleculesai.app` in the
  ASCII diagram with `<slug>.<env-domain>` plus a "no wildcard" note.
- Renames section 5 to "Cloudflare: per-tenant CNAMEs (no wildcard)"
  and explains that NXDOMAIN on unknown slugs is correct, that
  `getaddrinfo ENOTFOUND` in tests means the slug is unprovisioned
  (not an infra bug), and that the same model applies to both
  staging and production.

Hongming Wang 651fe00998 Merge pull request #113 from Molecule-AI/docs/runtime-mcp-claude-21-install
Claude Code 2.1+ install: modern -e flags + ~/.claude.json shape
2026-05-01 18:30:06 -07:00
Hongming Wang 1e8f9dc295 docs(runtime-mcp): Claude Code 2.1+ install — modern -e flags + ~/.claude.json shape
Older `claude mcp add ... -- env VAR=val molecule-mcp` snippets land as
`command: "env"` with positional args, which is fragile across 2.1.x
patch builds and unfamiliar to anyone reading `~/.claude.json` directly.
The post-2.1 CLI also rejects the form without a `--` between flags and
command (external feedback in #112).

Replace both snippets (basic install + identity-with-skills) with:
1. Modern CLI form using `-e KEY=VAL` and an explicit `--`.
2. Parallel `~/.claude.json` JSON shape under top-level `mcpServers` for
   user scope (or `.mcp.json` in project root for project scope), so
   users on any 2.1.x patch level have an authoritative reference if
   the CLI form misbehaves.

Add a Troubleshooting entry for the two common 2.1+ CLI rejections, and
fix the broken `[Install](#install)` cross-link in the dev-channels
section to point at `[Step 2](#claude-code)`.

Closes Molecule-AI/docs#112.

2026-05-01 17:52:24 -07:00
Hongming Wang 9c28fcf22c docs(runtime-mcp): document channel envelope attributes table
Adds a per-attribute reference table for the <channel> tag (push
path) and the equivalent JSON shape (poll path) so the agent — and
operators reading the docs — know what metadata to expect for every
inbound message.

Covers the new peer_name, peer_role, agent_card_url fields landing
with the wheel-side enrichment in molecule-core#2471, including the
registry-lookup graceful-degrade rule (lookup failure → attrs
absent, push still delivers) and the deterministic agent_card_url
construction (present even on registry outage).

Includes a worked example of a peer_agent push so a reader can copy
the wire shape into their own host bridge if they need to validate
what they're seeing.

docs(runtime-mcp): tagged server:molecule form for --dangerously-load-development-channels
2026-05-01 17:12:35 -07:00
Hongming Wang 49f95877f8 docs(runtime-mcp): tagged server:NAME form for --dangerously-load-development-channels
Claude Code 2.1.x changed the flag's signature to require an allowlist
of tagged entries — `server:<name>` for manually-configured MCP
servers, `plugin:<name>@<marketplace>` for plugin channels. The
previous bare-switch form was rejected with `argument missing`, and
an untagged value returns `entries must be tagged`.

Doc updates:
- Replace bare-flag references with tagged form throughout (env-var
  table, push-path narrative, capability matrix)
- Add a worked example showing `claude --dangerously-load-development-
  channels server:molecule` and the `Listening for channel messages
  from: server:molecule` confirmation header so operators have a
  visible signal that push is live
- Note the multi-server form (space-separated tagged entries)
- Three new troubleshooting entries:
  * `argument missing` → forgot the value
  * `entries must be tagged` → forgot the tag
  * `Control request timeout: initialize` → embedded the flag in an
    SDK options bundle as `{flag: None}` instead of `{flag:
    "server:molecule"}` — covers the workspace-side regression we
    caught live on dd40faf8 on 2026-05-01

Hongming Wang c6494de5ad docs: wrap <ws-id> placeholders in backticks to fix MDX build
Bare <ws-id> in headings emitted a `raw` HAST node that the renderer
couldn't handle ("Cannot handle unknown node `raw`"). Wrapping in
backticks renders as inline code instead of being parsed as JSX/HTML.

Hongming Wang c5421c61f5 docs: fix MDX build — escape <1 + drop Callout JSX
Two errors caught by the docs build CI on PR #98:

1. external-agents.mdx line 15 had `<1 min.` — the literal `<` made the
   MDX parser try to read it as a JSX tag opener. Replaced with prose
   "under a minute" — equivalent meaning, no escape gymnastics.
2. claude-code-channel-plugin.md used `<Callout type="info">` JSX, but
   the rest of /content/docs/guides/ is plain .md (no JSX). The .md
   loader can't resolve the Callout component → "Cannot handle unknown
   node `raw`". Replaced with a `> **Note:**` blockquote — same visual
   hierarchy, plain markdown.

Verified locally that the offending characters are gone; build CI on
push will re-run and should now pass.

Hongming Wang 2ccd4b99d0 docs: add Claude Code Channel Plugin guide + cross-references
Adds /docs/guides/claude-code-channel-plugin.md — the canonical guide
for connecting a Claude Code session as a Molecule external workspace
via the new Molecule-AI/molecule-mcp-claude-channel plugin. Polling-
based; no tunnel required.

Cross-references added:
- content/docs/external-agents.mdx — new "Pick the right path" table
  at top, distinguishing Claude Code (channel plugin) from generic
  HTTP-speaking agents (this page) at first glance.
- content/docs/guides/external-workspace-quickstart.md — short
  redirect callout near the top so laptop-Claude-Code users are
  routed to the channel plugin guide instead of the tunnel-required
  quickstart.

Per molecule-core's #2060 content-routing policy, public-facing docs
live in this repo. The plugin source + README live separately at
github.com/Molecule-AI/molecule-mcp-claude-channel; this guide
duplicates the operator-facing setup steps and adds Molecule-specific
context (how to get workspace_id + token from canvas, how /activity
shows up, troubleshooting against /activity endpoint shape).

Hongming Wang b26d7ee9b2 docs(mcp): rewrite inbound-delivery section for dual push+poll contract
Mirrors molecule-core feat/universal-push-via-instructions: documents
the universal poll path (instructions field → every MCP client) plus
the optional push path (notifications/claude/channel for Claude Code
with the dev-channels flag or a future allowlist entry).

Honesty pass on the prior text: previous version claimed push works
"automatically" and "there is no config flag to toggle." That was
true for the wire shape but false for live UX — standard `claude`
launches without --dangerously-load-development-channels silently
drop the notification, and non-Claude clients ignore the Claude-
namespaced method entirely. New text spells out exactly which clients
get push, which get poll, and the per-client capability matrix.

Adds MOLECULE_MCP_POLL_TIMEOUT_SECS to the env-var table — the new
operator knob landed in the wheel.

Successor to #44/#49 (which closed without the flag caveat).

2026-05-01 00:01:09 -07:00
Hongming Wang 28600d7956 docs(workspace-runtime): correct smoke-gate caveat factual errors
Two errors in the merged caveat (#107):

1. Claimed the stub RequestContext "carries an empty user message"
   — actually carries "smoke test" text (smoke_mode.py:76 calls
   `new_text_message("smoke test")`, with the explicit comment
   that it's "enough that extract_message_text(context) returns
   non-empty input"). Adapter authors gating smoke-mode behavior
   on extract_message_text(ctx) == "" would have a logic that
   never fires.

2. Described only the timeout-pass path. The harness also returns
   0 on ANY non-import exception (smoke_mode.py:135-143) — the
   bare `except Exception` block treats RuntimeError, auth errors,
   validation errors etc. as "downstream of the import gate" and
   exits clean. Spelling out all three pass cases (clean return,
   timeout, non-import exception) is the honest description.

Caught while re-reading smoke_mode.py to verify claims for a
review pass — found I had asserted both behaviors from memory
without checking, exactly the failure mode my e2e-test memory
just got a worked-example update about.

2026-04-30 23:56:05 -07:00
Hongming Wang ec78c7637b docs(workspace-runtime): clarify what the boot-smoke gate does NOT prove
A green gate means imports are healthy enough that
executor.execute() reaches its body. It does NOT prove that
execute() produces the right output: adapters with real I/O
inside execute() (subprocess to a gateway, httpx call upstream)
time out under the 5s harness window, and the gate treats a clean
timeout as success.

Surfaced while running publish-image across all 8 templates: the
openclaw smoke "passed" with timing-out behavior in execute()
because OpenClawA2AExecutor proxies to a subprocess that doesn't
exist in the smoke env. Reading the green check, future operators
might over-trust it as a runtime-correctness signal — it isn't.

Add a "What the gate does NOT prove" subsection so readers don't
mistake the import-regression coverage for an integration test.

2026-04-30 22:51:42 -07:00
Hongming Wang 1ccd92e0c8 docs(workspace-runtime): document MOLECULE_SMOKE_MODE adapter contract
The publish-image boot-smoke gate (molecule-core#2275) invokes the
runtime with MOLECULE_SMOKE_MODE=1 + stub creds to catch lazy
imports inside executor.execute(). Adapters whose setup() does
real I/O (subprocess spawn, network calls, uid-sensitive writes)
need to opt out of that I/O when MOLECULE_SMOKE_MODE=1, otherwise
the gate fails before reaching the runtime's smoke short-circuit.

This documents:
- the contract (one-line opt-out for Python adapter.setup() and
  shell entrypoints that wrap molecule-runtime)
- which boot stages the gate exercises
- the stub env the harness sets so adapters can reason about what
  they can rely on under smoke mode

Surfaced when running publish-image across all 8 workspace
templates: openclaw and hermes hit the contract gap because both
spawn real gateway subprocesses in setup; six others passed
without any contract awareness because their setup is light.

Hongming Wang 403725b970 feat(docs): align doc.moleculesai.app chrome with landing's warm-paper design
Brings the docs site in visual parity with moleculesai.app so docs,
marketing, and the canvas read as one product. Five focused changes
inside the existing fumadocs shell — no MDX or content touched, no
runtime/build dep changes:

- global.css: override fumadocs @theme tokens with the warm-paper
  palette (#fafaf7 bg, #15181c ink, #3b5bdb governance blue,
  #efece4 muted, #e6e2d8 border). Dark mode keeps fumadocs' neutral
  defaults so dark-pref readers still get a readable docs site.

- layout.tsx: swap Inter → Geist (sans) + JetBrains Mono (code),
  matching the landing's font stack. Wired through @theme so
  Tailwind's font-sans / font-mono utilities pick them up.

- layout.config.tsx: brand the topbar — inline Molecule logo SVG +
  "Molecule AI · DOCS" lockup, plus three external links to the rest
  of the surface (Platform → app, Marketplace → market, Landing →
  www) and the org GitHub. Mirrors the landing's collapsed nav.

- (home)/page.tsx: replace the stock fumadocs landing with a
  hero-style page matching the landing — statusbar strip, "Phase 35
  Marketplace public beta" eyebrow, the same shimmering h1 copy,
  three quick-start lane cards (Build a workspace / Run an
  organisation / Publish to the Marketplace) pointing into the docs
  tree.

Build is clean (106 static pages still generate). Existing /docs/*
pages inherit the new tokens via fumadocs' DocsLayout, so the entire
site shifts to the warm-paper aesthetic without touching MDX.

Hongming Wang f1ed8784ff docs(2429): document 410 Gone for removed workspaces
Follow-up C to molecule-core#2449 + #2451 (a2a-client) +
molecule-mcp-claude-channel#22 (channel bridge):

- runtime-mcp.mdx Troubleshooting: new section explaining the 410
  startup-time error from `get_workspace_info`, contrasting it with
  the heartbeat-401 escalation (which is the steady-state cure), and
  documenting the `?include_removed=true` opt-in for audit tooling.
- external-agents.mdx Lifecycle: expanded the `removed` status with
  a per-caller behavior table so operators know exactly what each
  surface (wheel heartbeat, MCP tool, channel bridge, raw curl) looks
  like for a removed workspace.

Both pages link back to the underlying PR so the audit trail is
single-click navigable from the docs.

Hongming Wang 798294b62a docs(runtime-mcp): document MCP 2024-11-05 spec compliance
Adds a "MCP spec compliance" subsection to runtime-mcp.mdx that:

- Lists which MCP methods the wheel implements + how
- Notes the wheel speaks protocol version 2024-11-05 with only the
  `tools` capability (no streaming, no logging)
- Clarifies that notifications/claude/channel is the only non-spec
  method emitted, and that clients which don't handle it discard
  per JSON-RPC semantics
- States explicitly that any spec-compliant MCP client can drive
  the wheel (Claude Code, Cursor, Cline, OpenCode, hermes-agent,
  or anything else that opens MCP stdio)

This is the deliverable for verifying cross-client compatibility.
The wheel uses no client-specific behavior, so the verification
reduces to "does your client speak MCP 2024-11-05?" — which all
the listed clients do.

Hongming Wang 6a99eb0896 docs(runtime-mcp): document push-UX + expand troubleshooting
Two additions to the universal MCP runtime page:

1. New "Push-UX for notification-capable hosts" subsection explains
   that the wheel emits notifications/claude/channel on every new
   inbound message — Claude Code (and any compliant client) gets
   push-style interrupts, poll-only runtimes silently fall back to
   wait_for_message / inbox_peek. Same wheel for both, no config flag.

2. Three new troubleshooting entries from real install pitfalls:
   - Tools 401 after working: workspace was deleted from the canvas
     (token revoked); regenerate from Tokens tab
   - claude mcp list shows new config but /mcp reconnect still uses
     cache — must fully exit + relaunch the runtime
   - command not found from inside runtime: PATH differs from
     interactive shell (esp. macOS GUI-launched apps); use the
     absolute path from `which molecule-mcp`

Hongming Wang f8a9b06323 docs: add Bring Your Own Runtime (MCP) page
The universal molecule-mcp wheel is the recommended path for any
MCP-aware runtime — Claude Code, hermes-agent, OpenCode, Cursor, Cline,
custom MCP clients — to join the canvas as a first-class external
workspace. Until now this path had no docs page; users either inferred
it from internal PRs or got pointed at external-agents.mdx (the manual
HTTP+heartbeat path that pre-dates the wheel).

New runtime-mcp.mdx covers:
  * Single install (pip install --user molecule-ai-workspace-runtime)
  * Per-runtime config snippets (Claude Code, Hermes, generic JSON,
    Cursor/Cline)
  * Tool surface (delegate_task, wait_for_message, inbox_peek/pop,
    send_message_to_user, commit_memory/recall_memory)
  * Heartbeat/lifecycle behaviour and the new escalation message
    landed in molecule-core PR #2425
  * When to use this vs. the manual external-agents path
  * Troubleshooting: stale MCP cache, 401 register failure, PATH issues

Cross-links:
  * external-agents.mdx now leads with a Callout pointing MCP-runtime
    users at the new page; keeps the manual path for non-MCP agents
  * meta.json registers the new page under the main docs nav between
    schedules and external-agents (related onboarding flow)

Build verified: `npm run build` generates 106 pages including the new
/docs/runtime-mcp.

rabbitblood 017f846ce2 security(incident-log): redact full token values from F1088 incident report
The INCIDENT_LOG.md F1088 entry documented three production credentials
that leaked via molecule-core PR #1098 (commit d513a0c) and were then
INCLUDED IN PLAINTEXT in the documentation itself — the incident report
became a secondary leak surface.

Status of the three tokens (per the report's own Blast Radius table):
- MiniMax (sk-cp-...KVw): revoked / endpoint inactive
- GitHub PAT (github_pat_...hsIJLIL): revoked, confirmed 401
- Admin token (HlgeMb8...ShARE=): treated as active, rotation pending

Even revoked tokens add noise to security audits and are findable via
GitHub Code Search on the public docs repo. This PR replaces the full
values with the short-suffix convention already in use in the same
file's Blast Radius table, preserving the audit trail without the
public-search surface.

Side note: caught by Molecule-AI/molecule-core#2109's secret-scan
workflow on PR #96 (the org-wide rollout that reused this same regex
set caught its own first real find before the rollout PR even merged).

The full values remain in molecule-core git history per F1088's
explicit closure decision (no BFG scrub required); this PR doesn't
change that.

10. Start the skill watcher when skills are configured.
11. Serve the A2A app through Uvicorn.
## Boot-Smoke Contract (`MOLECULE_SMOKE_MODE`)
The image-publish CI pipeline runs each template's image with `MOLECULE_SMOKE_MODE=1` to exercise lazy imports inside `executor.execute()` against stub credentials and no network. The runtime detects the env var, invokes `executor.execute()` once with a stubbed `RequestContext` and a short timeout, then exits — registration, heartbeats, and the A2A server are skipped.
This catches lazy imports that pure `python3 -c "import adapter"` smokes miss: imports nested inside `if`-branches, deferred until first call, or behind `importlib.import_module()`.
### What adapter authors need to do
**Most adapters need to do nothing.** If `setup()` only writes files, parses config, or instantiates Python objects, the smoke gate just works.
**Adapters whose `setup()` does real I/O must opt out of that I/O under smoke mode.** This applies to:
- spawning subprocesses that require valid credentials (e.g. a gateway daemon)
- making real network calls
- writing to filesystem locations that need a specific uid/gid the smoke harness can't guarantee
The contract:
```python
async def setup(self, config: AdapterConfig) -> None:
if os.environ.get("MOLECULE_SMOKE_MODE") == "1":
return # skip real I/O; runtime's smoke short-circuit handles the rest
# ... real setup ...
```
For shell entrypoints that wrap `molecule-runtime`:
```bash
if [ "${MOLECULE_SMOKE_MODE:-0}" = "1" ]; then
exec molecule-runtime
fi
```
### What gets exercised under smoke mode
- All `/app/*.py` modules import cleanly (covered by a separate static-import smoke step)
- `adapter.setup()` runs (with the opt-out above for I/O-heavy adapters)
- `adapter.create_executor()` runs
- `executor.execute()` is invoked once against a stub `RequestContext`/`EventQueue` with `MOLECULE_SMOKE_TIMEOUT_SECS` (default 5s); a clean timeout exits 0, an import error exits non-zero
### What the gate does NOT prove
A green gate means **"imports are healthy enough that `executor.execute()` reaches its body"** — that's the regression class the gate exists to catch (lazy `from x import y` inside an `if`-branch, or `importlib.import_module()` on a path that breaks after a wheel bump).
It does **not** prove that `execute()` produces the right output for real input. The harness reports PASS in three distinct cases:
1. **Clean return** — execute() ran to completion within the timeout.
2. **Timeout** — execute() was still running when the timer fired (typical for adapters that do real I/O inside execute(): subprocess to a gateway, httpx call to an upstream LLM).
3. **Any non-import exception** — execute() raised `RuntimeError`, auth errors, validation errors, etc. The harness only fails on `ImportError`/`ModuleNotFoundError`.
The stub `RequestContext` carries a non-empty `"smoke test"` text message (so adapters relying on `extract_message_text(ctx)` returning input still work), and the harness never drains the `EventQueue` — what `execute()` writes back is ignored.
If you need correctness coverage, write a separate integration test that runs the workspace against real or mocked infrastructure — the smoke gate is a strict subset.
### Stub env the smoke harness sets
| Var | Value |
|---|---|
| `MOLECULE_SMOKE_MODE` | `1` |

### 5. Cloudflare: staging subdomain
### 5. Cloudflare: per-tenant CNAMEs (no wildcard)
Option A (simple): `*.staging.moleculesai.app` with its own tunnel/worker
Option B (full): separate Cloudflare zone for staging (overkill)
There is **no `*.staging.moleculesai.app` wildcard record** and there is no
`*.moleculesai.app` wildcard either. The control plane writes a per-tenant
CNAME at provision time, pointing `<slug>.<env-domain>` at that tenant's
Cloudflare tunnel (`<tunnel-id>.cfargotunnel.com`).
Recommend Option A:
- Add `staging.moleculesai.app` DNS records
- Staging tenants get `slug.staging.moleculesai.app` subdomains
- Production tenants get `slug.moleculesai.app` (unchanged)
Verified in `molecule-controlplane/internal/provisioner/ec2.go` — the
provisioner calls `Tunnel.CreateTunnelDNS(ctx, slug, domain, tunnelID)`
during workspace provision, then records a `cf_dns` row in
`tenant_resources` with `type=CNAME` for symmetric create/delete audit.
Implications for staging:
- Staging tenants get `<slug>.staging.moleculesai.app` only **after** they
are provisioned through the staging control plane. The CNAME is
written as part of `Provision()`.
- Production tenants get `<slug>.moleculesai.app` the same way, against
the production CP.
- Pre-provision, an unknown slug returns **NXDOMAIN**. This is correct
behavior, not a regression — there is no wildcard to catch the lookup.
- Tests that hit a staging slug they have not provisioned themselves
will fail with `getaddrinfo ENOTFOUND` (Node) or `Name or service not
known` (curl). The fix is to provision your own slug against the
staging CP first; do not file this as an infrastructure bug.
The same model applies to both environments — the only difference is
the parent zone (`staging.moleculesai.app` vs `moleculesai.app`) and the
CP that writes the records.

Run [Claude Code](https://claude.com/claude-code) on your laptop and have it appear on the Molecule AI canvas as a first-class external workspace. Inbound A2A messages from peer workspaces surface as conversation turns; replies route back through Molecule's A2A endpoints.

---
## Step 1 — Create the workspace
In your Molecule canvas:
1. Click **+ New workspace**
2. Choose **External** runtime
3. Set tier as needed; click **Create**
4. The "Connect your external agent" modal opens — switch to the **Claude Code** tab
5. Copy the entire snippet (everything from the `mkdir -p` line through `claude --channels ...`)
Or via API:
```bash
curl -X POST "$MOLECULE_PLATFORM_URL/workspaces" \
-H "Content-Type: application/json" \
-d '{"name": "My Claude Code", "external": true, "tier": 2}'
```
The response includes `claude_code_channel_snippet` — same content as the canvas tab, ready to paste.
## Step 2 — Set up the channel config
Run the snippet from Step 1. It does two things:
```bash
mkdir -p ~/.claude/channels/molecule
cat > ~/.claude/channels/molecule/.env <<'EOF'
MOLECULE_PLATFORM_URL=https://your-tenant.staging.moleculesai.app
MOLECULE_WORKSPACE_IDS=ws-uuid-1
MOLECULE_WORKSPACE_TOKENS=<paste auth_token from create response>
EOF
chmod 600 ~/.claude/channels/molecule/.env
```
Replace the token placeholder with the workspace bearer from Step 1.
## Step 3 — Launch Claude Code
```bash
claude --channels plugin:molecule@Molecule-AI/molecule-mcp-claude-channel
```
You should see on stderr (use `--debug` to surface):
```
molecule channel: connected — watching 1 workspace(s) at https://your-tenant.staging.moleculesai.app
workspaces: ws-uuid-1
poll: every 5000ms with 30s window
```
That's it — the workspace is live on the canvas with a purple **REMOTE** badge, and any A2A traffic the workspace receives surfaces as conversation turns in your Claude Code session.
---
## How replies work
When a peer's message lands in your session, you'll see a turn with structured metadata:
```json
{
"method": "notifications/claude/channel",
"params": {
"content": "Hey, can you take a look at this? <issue body>",
"meta": {
"source": "molecule",
"workspace_id": "ws-uuid-1",
"peer_id": "ws-uuid-pm-coordinator",
"method": "user_message",
"activity_id": "act-...",
"ts": "2026-04-29T..."
}
}
}
```
Reply normally — Claude calls the `reply_to_workspace` MCP tool with `peer_id` from the meta block, and the response flows back through `POST /workspaces/:peer_id/a2a` so peers see it just like any other A2A message.
---
## Multi-workspace setup
Watch multiple workspaces from a single Claude Code session by comma-separating the lists. Both must have the same length and order:
```bash
MOLECULE_WORKSPACE_IDS=ws-pm,ws-researcher,ws-engineer
MOLECULE_WORKSPACE_TOKENS=tok-pm,tok-researcher,tok-engineer
```
When Claude replies, the `reply_to_workspace` tool requires `workspace_id` (which of the watched workspaces to reply AS) explicitly. With a single workspace it's implicit.
---
## Configuration reference
| Variable | Default | Purpose |
|---|---|---|
| `MOLECULE_PLATFORM_URL` | (required) | Tenant base URL (no trailing slash) |
| `MOLECULE_WORKSPACE_IDS` | (required) | Comma-separated workspace UUIDs to watch |
| `MOLECULE_WORKSPACE_TOKENS` | (required) | Comma-separated bearer tokens, **same order as IDs** |

| `MOLECULE_STATE_DIR` | `~/.claude/channels/molecule` | Override state directory (testing) |
---
## Architecture notes
### Why polling instead of push?
The [Python SDK external-agent flow](/docs/guides/external-agent-registration) uses **push**: register an inbound URL, platform POSTs A2A to that URL. Lower latency but requires a tunnel (ngrok / Cloudflare) or static IP — non-trivial for laptop sessions.
This plugin uses **polling** as the default because it works through every NAT/firewall with zero infra. Cost: up to `MOLECULE_POLL_INTERVAL_MS` of inbound latency. For production setups where lower latency matters, push mode is on the v0.2 roadmap.
### Why the 30s window over a 5s interval?
A single missed tick (transient network blip, GC pause, laptop sleep) shouldn't lose messages. The plugin re-fetches the last 30 seconds on every poll and dedups by `activity_id`, so 25 seconds of overlap is the recovery margin. Increase `MOLECULE_POLL_WINDOW_SECS` for noisier networks.
### Singleton lock
Only one channel server runs per host — multiple instances would race the dedup state and double-deliver. The plugin maintains a PID file at `~/.claude/channels/molecule/bot.pid` and on startup kills any stale predecessor. This mirrors the [`@claude-plugins-official/telegram`](https://github.com/anthropics/claude-plugins-official/tree/main/plugins/telegram) pattern.
---
## Troubleshooting
### "molecule channel: required config missing"
The plugin started before you filled in `.env`. Re-run the snippet from Step 2, then re-launch Claude Code.
### "molecule channel: poll `<ws-id>` returned 401"
Bearer token mismatch. Two common causes:
- The token in `MOLECULE_WORKSPACE_TOKENS` doesn't match the workspace whose ID is in the corresponding position of `MOLECULE_WORKSPACE_IDS`. Verify same-order pairing.
- The workspace was rotated and the token was revoked. Generate a new token from the canvas Settings tab (or `POST /admin/workspaces/:id/tokens`).
### "molecule channel: poll `<ws-id>` returned 404"
Either the workspace doesn't exist or the `MOLECULE_PLATFORM_URL` is wrong. Confirm:
```bash
curl -fsS "$MOLECULE_PLATFORM_URL/workspaces/$WS_ID" \
-H "Authorization: Bearer $WS_TOKEN" | jq '.workspace.id'
```
### A2A messages aren't surfacing
Check that the watched workspace is actually receiving them — the plugin only pulls `activity_logs` rows whose `activity_type = a2a_receive`. If peers aren't sending to this workspace, there's nothing to surface. Verify with:
```bash
curl -fsS "$MOLECULE_PLATFORM_URL/workspaces/$WS_ID/activity?type=a2a_receive&limit=10" \
-H "Authorization: Bearer $WS_TOKEN" | jq
```
If that returns events but Claude doesn't see them, file an issue at [`Molecule-AI/molecule-mcp-claude-channel`](https://github.com/Molecule-AI/molecule-mcp-claude-channel/issues) with the workspace_id + sample event.
---
## Limitations (v0.1)
- **Polling-only inbound.** No push mode yet; latency floor is `MOLECULE_POLL_INTERVAL_MS`.
- **No pairing flow.** Tokens are configured manually via `.env`; no canvas-side approval handshake.
- **No file-attachment download.** URLs surface in the meta block; the host fetches on-demand.
- **No outbound channel-init.** The plugin only sends replies (in response to inbound A2A); starting a fresh A2A conversation initiated FROM the Claude Code side requires a future `start_workspace_chat` tool.
Track the v0.2 roadmap on the [plugin repo's README](https://github.com/Molecule-AI/molecule-mcp-claude-channel#limitations-v01).

title: Marketplace
description: A tiered library of plugins, agents, and bundles you can mount into any Molecule workspace.
---
## Overview
The Molecule **Marketplace** is the distribution surface for reusable agent
infrastructure. It surfaces three tiers of artifacts — from a single MCP
plugin to a full team topology — and the same governance, memory, and audit
substrate runs underneath each one.
You browse and install via the Marketplace UI at
[`https://moleculesai.app`](https://moleculesai.app), or pin entries from
your `workspace.yaml` for reproducible deployments.
---
## Three Tiers
| Tier | Name | Granularity | Mount as |
|------|------|-------------|----------|
| **L1** | Plugins | A single MCP server / tool pack | Tool capability on an agent or workspace |
| **L2** | Agents | A prebuilt single-agent skill (prompts + tools + policy) | Workspace member |
| **L3** | Bundles | A full team topology (root + children with their own scopes) | Workspace |
The tier model is intentionally additive — an L3 Bundle is composed of L2
Agents, which in turn use L1 Plugins. Forking a Bundle gives you the lineage
to swap any constituent piece without rewiring the operating model.
### L1 — Plugins
Plugins are MCP servers or agentskills.io packs. Examples:
- `postgres` — read/write Postgres with role-scoped credentials
- `slack` — post and search Slack with workspace-scoped tokens
- `linear` — create / triage / comment on Linear issues
- `gh-actions` — query and dispatch GitHub Actions runs
- `sentry` — read incident timeline, ack alerts
Plugins follow the [two-axis source/shape model](/docs/plugins) and install
from either a curated `local://` source or a pinned `github://owner/repo#tag`.
### L2 — Agents
Agents are single-purpose skills mounted as a workspace member. They ship with:
- A **system prompt** baked in
- A **tool manifest** specifying which L1 plugins they require
- A **policy** declaring scope reads/writes and approval requirements
Examples:
- `code-reviewer` — five-axis review, posts inline comments via `gh-actions`
- `oncall-triager` — reads Sentry, drafts a runbook step, requests approval before paging
- `churn-analyst` — periodic Postgres + Stripe rollup, posts a weekly Slack summary
Mount an agent via the workspace UI or `workspace.yaml`:
```yaml
members:
- kind: agent
source: marketplace://l2/code-reviewer
version: ^1.2.0
scopes:
- read: pull_requests
- write: pull_request_comments
```
### L3 — Bundles
Bundles are complete team topologies. A bundle ships:
- A **root agent** that coordinates the team
- One or more **child agents**, each with its own scope, memory, and tool
list
- A **policy graph** declaring which scopes the root can write through and
which approvals route to humans
Examples:
- `growth-team` — root strategist + content-writer + analytics-rollup +
experiment-designer
- `platform-ops` — root SRE + on-call triager + change-reviewer +
incident-scribe
- `revenue-pod` — root commercial lead + churn-analyst + cs-summarizer +
expansion-prospector
Mount a bundle as a workspace:
```yaml
workspace:
bundle: marketplace://l3/platform-ops
bundle_version: ^0.4.0
overrides:
members:
change-reviewer:
scopes:
- read: ["github:Molecule-AI/*", "linear:eng"]
```
Forking is encouraged — the bundle author publishes the operating model;
your team tunes it for your processes without rebuilding the substrate.
---
## Trust Tiers
Every Marketplace entry carries a **trust tier** that signals review depth
and supply-chain provenance:
| Trust | Vetting | Provenance |
|-------|---------|------------|
| **Verified** | Reviewed by Molecule for safety, prompt-injection resistance, and policy correctness | Published from a Molecule-controlled identity |
| **Partner** | Reviewed by a Marketplace partner; carries the partner's identity badge | Published from a verified partner account |
| **Community** | Self-published; static analysis + sandbox runtime; no human review | Pinned to a specific commit SHA |
The trust tier is shown on every listing card and gated by enterprise
policy: organizations on the Enterprise plan can restrict installs to
Verified-only via `policy.marketplace.min_trust = verified`.
---
## Installing from the Marketplace
Browse listings at [`https://moleculesai.app`](https://moleculesai.app).
Each card shows tier (L1/L2/L3), trust badge, runtime compatibility, and
required scopes. The "Install" flow:
1. Picks a workspace (or creates a new one) to mount into.
2. Surfaces required scopes for review and approval.
3. Pins to a specific version (semver range, exact tag, or commit SHA).
4. Writes the entry into your `workspace.yaml` and triggers a workspace
redeploy.
You can also install non-interactively:
```bash
curl -X POST https://app.moleculesai.app/cp/orgs/$ORG/marketplace/install \
-H "Authorization: Bearer $CP_ADMIN_API_TOKEN" \
-H "Content-Type: application/json" \
-d '{
"tier": "l2",
"slug": "code-reviewer",
"version": "^1.2.0",
"workspace_id": "ws_abc123"
}'
```
---
## Listing on the Marketplace
If you have built reusable agent infrastructure — a plugin, agent, or
bundle — you can list it on the Marketplace and reach every Molecule

title: Listing on the Marketplace
description: How builders ship plugins, agents, and bundles to every Molecule organization.
---
## Overview
The Marketplace is open to external builders. If you have authored reusable
agent infrastructure — an MCP plugin, a single-agent skill, or a full team
bundle — you can list it and reach every Molecule organization. We handle
distribution, billing, and policy; you keep the IP and the upgrade cadence.
This page walks through the three-step workflow: **Build · List · Earn**.
---
## 1. Build
You author your artifact against the open Molecule SDK. The same primitives
we use internally are available to you:
- **Workspace** — the durable boundary for memory, members, and policy
- **A2A** — agent-to-agent messaging, used to talk to runtimes you don't
own (LangGraph, CrewAI, etc.)
- **Memory scopes** — hierarchical, governance-aware persistence
- **Audit** — every action is captured at the orchestration layer
Pick the tier that matches your artifact's granularity:
### L1 — Plugins
A plugin is an MCP server (or an agentskills.io pack). The
[two-axis source/shape model](/docs/plugins) describes how the workspace
runtime loads it. Authoring requirements:
- A `plugin.yaml` manifest declaring tools, required scopes, and runtime
compatibility.
- A README documenting the tool surface and side effects.
- For MCP plugins: an HTTP or stdio MCP server pinned to a tagged commit.
A reference plugin lives at
[`Molecule-AI/molecule-ai-plugin-template`](https://github.com/Molecule-AI/molecule-ai-plugin-template).
### L2 — Agents
An agent is a single workspace member with a baked-in prompt + tools +
policy. Authoring requirements:
- An `agent.yaml` manifest declaring system prompt, required L1 plugins,
scope reads/writes, and approval triggers.
- A `prompts/` directory with the system prompt and any reusable templates.
- A `tests/` directory exercising the prompt against canned scenarios.
Reference: [`Molecule-AI/molecule-ai-agent-template`](https://github.com/Molecule-AI/molecule-ai-agent-template).
### L3 — Bundles
A bundle ships a complete team topology — a root agent plus children, each
with its own scope and memory. Authoring requirements:
- A `bundle.yaml` declaring members, their scopes, and the policy graph
(which scopes the root can write through, which approvals route to
humans).
- A `members/` directory containing member-specific overrides if any
member is a fork of an L2 agent.
- A `topology.svg` diagram (auto-rendered from `bundle.yaml`, but you can
override).
Reference: [`Molecule-AI/molecule-ai-bundle-template`](https://github.com/Molecule-AI/molecule-ai-bundle-template).
---
## 2. List
Submit through the **Creator Portal** at
[`https://moleculesai.app/creators`](https://moleculesai.app/creators).
The submission flow:
1. **Connect** — link the GitHub repository hosting your artifact. We pull
from tagged releases; we never re-tag or modify your code.
2. **Manifest check** — we validate `plugin.yaml` / `agent.yaml` /
`bundle.yaml` against the schema for your tier and surface any gaps.
3. **Static analysis** — credential-shape scan, prompt-injection-pattern
scan, and dependency vulnerability check on every tagged release.
4. **Sandbox boot** — your artifact is mounted into a throwaway workspace
to verify it boots, declares its scopes correctly, and surfaces a
reasonable error path.
5. **Trust tier** — every artifact starts at **Community**. Apply for
**Partner** or **Verified** review once you have a couple of releases
under your belt.
Pricing is configured at submission:
- **Free** — no charge to install.
- **Per-seat** — a flat monthly amount per workspace member that mounts
the artifact.
- **Per-use** — metered against a unit you define (token calls, runs,
alerts handled).
- **Hybrid** — base seat fee plus metered overages.
You can change pricing on subsequent releases; existing installs are
grandfathered to the version they pinned.
---
## 3. Earn
Once your listing is live, you receive:
- **Distribution** — every Molecule organization sees your listing in the
Marketplace UI, gated only by their policy (`min_trust`, region, etc.).
- **Billing** — Molecule handles the charge to the installing
organization, deducts the platform fee (15% as of writing; check the
current rate in the Creator Portal), and pays out monthly.
- **Audit visibility** — you see install counts, version distribution,
and aggregated usage metrics in the Creator Portal. You do **not** see
per-organization data.
- **Upgrade cadence** — semver: bump tags, organizations on a `^range`
pin pull updates on their next workspace redeploy. Major bumps require
re-approval of any new scopes.
---
## Policy & Safety
By listing, you agree to:
- **No exfiltration** — your code does not transmit organization data
outside the scopes it declares.
- **Pinned releases** — every version is pinned to an immutable commit;
retagging is not permitted.
- **Disclose model usage** — if your agent calls an LLM API, declare the
provider and model so enterprise plans can route through their own
keys.
- **Respect approval triggers** — if your `agent.yaml` declares a scope
that requires human approval (e.g. `write: pull_request_merge`), you
must call the approval API before acting.
Listings that violate these terms are de-listed; refunds for affected
installs are paid from your account.
---
## Maintenance
Once a listing is live, you can:
- Push new tagged releases — they enter the static-analysis + sandbox
flow automatically.
- Mark older versions as **deprecated** to nudge installs to upgrade.
- File **security advisories** that surface to every organization on a
vulnerable pinned version.
- Yank a release in the rare case of a critical bug; organizations
pinned to the yanked tag are notified and offered the next safe version.

title: Bring Your Own Runtime (MCP)
description: Add Claude Code, Hermes, OpenCode, Cursor, or any MCP-aware agent to the Molecule canvas as a first-class workspace using the universal molecule-mcp wheel.
---
import { Callout } from 'fumadocs-ui/components/callout';
The universal `molecule-mcp` wheel lets any MCP-aware agent runtime
join the Molecule canvas as a first-class external workspace. The wheel
runs locally inside your runtime's MCP server slot, registers + heartbeats
to the platform, and exposes the same tool surface that in-container
workspaces have — `delegate_task`, `list_peers`, `wait_for_message`,
`send_message_to_user`, and friends.
Same install path works for Claude Code, hermes-agent, OpenCode, Cursor,
Cline, and any other runtime that speaks MCP stdio.
```
Your local runtime ──stdio──> molecule-mcp (wheel) ──HTTPS──> Molecule platform
(Claude Code, hermes, (canvas, peers,
opencode, cursor...) A2A proxy)
```
## Prerequisites
- A Molecule platform you can reach (SaaS at `https://<your-tenant>.moleculesai.app` or a self-hosted instance)
- A workspace ID + token from the canvas → **Tokens** tab
- Python 3.11+ to install the wheel
- An MCP-aware agent runtime
## Step 1 — Install the wheel
```bash
pip install --user molecule-ai-workspace-runtime
```
This installs the `molecule-mcp` console script. By default it lands at
`~/Library/Python/3.x/bin/molecule-mcp` on macOS or `~/.local/bin/molecule-mcp`
on Linux. Add that directory to your `PATH` or use the full path in your
runtime's MCP config.
```bash
which molecule-mcp
# /Users/you/Library/Python/3.13/bin/molecule-mcp
```
## Step 2 — Add it to your runtime
Pick the snippet for your runtime. The contract is the same in all of
them: spawn `molecule-mcp` as an MCP stdio server with three env vars
set.
### Claude Code
Two equivalent paths — pick whichever your version supports.
**CLI (Claude Code 2.1+):** pass each env var with `-e`, scope with
`-s user` so the server is available in every project, and put the
command after `--`:
```bash
claude mcp add molecule -s user \
-e WORKSPACE_ID=<your-workspace-uuid> \
-e PLATFORM_URL=https://<your-tenant>.moleculesai.app \
-e MOLECULE_WORKSPACE_TOKEN=<your-token> \
-- molecule-mcp
```
<Callout type="info">
Older docs used a `-- env VAR=val ... molecule-mcp` shell trick (with
`env` as the command). It still works but produces a less idiomatic
`~/.claude.json` entry and trips up the post-2.1 flag parser if you
forget the `--`. Prefer the `-e` form above.
</Callout>
**Direct edit of `~/.claude.json`:** add the entry under the **top-level
`mcpServers` key** (this is the user-scope location — available in
every project). If you'd rather scope it to a single project, use a
`.mcp.json` file in that project's root with the same `mcpServers`
shape.
```json
{
"mcpServers": {
"molecule": {
"type": "stdio",
"command": "molecule-mcp",
"args": [],
"env": {
"WORKSPACE_ID": "<your-workspace-uuid>",
"PLATFORM_URL": "https://<your-tenant>.moleculesai.app",
"MOLECULE_WORKSPACE_TOKEN": "<your-token>"
}
}
}
}
```
If `molecule-mcp` isn't on the PATH that Claude Code sees (common on
macOS — see [Troubleshooting](#command-not-found-molecule-mcp-from-inside-the-runtime)),
replace `"command": "molecule-mcp"` with the absolute path from `which molecule-mcp`.
Reconnect with `/mcp` (or restart the Claude Code session) and the tools
appear in the next turn.
### Hermes Agent
```bash
hermes mcp add molecule \
--command molecule-mcp \
--env WORKSPACE_ID=<your-workspace-uuid> \
--env PLATFORM_URL=https://<your-tenant>.moleculesai.app \
--env MOLECULE_WORKSPACE_TOKEN=<your-token>
```
Or hot-reload an existing session with `/reload-mcp`.
### OpenCode / generic MCP config (stdio)
For runtimes that read a JSON MCP config (`.mcp.json`, `mcp_servers.yaml`,
or similar):
```json
{
"mcpServers": {
"molecule": {
"command": "molecule-mcp",
"env": {
"WORKSPACE_ID": "<your-workspace-uuid>",
"PLATFORM_URL": "https://<your-tenant>.moleculesai.app",
"MOLECULE_WORKSPACE_TOKEN": "<your-token>"
}
}
}
}
```
### Cursor / Cline / other MCP clients
Most MCP clients accept the same `command` + `env` shape as the JSON
example above. Drop it into your client's MCP settings file
(typically `~/.cursor/mcp.json` for Cursor, the MCP Servers panel for
Cline) and restart the client.
## Optional — declare your identity & capabilities
Four additional env vars control how your workspace appears on the
canvas and how the wheel's inbound-delivery contract behaves:
| Env var | What it sets | Default |
|---|---|---|
| `MOLECULE_AGENT_NAME` | Display name on the canvas card | `molecule-mcp-{id[:8]}` |
| `MOLECULE_AGENT_DESCRIPTION` | One-line description in Details/Skills tabs | empty |
| `MOLECULE_AGENT_SKILLS` | Comma-separated skill names — e.g. `research,code-review,memory-curation` | `[]` |
| `MOLECULE_MCP_POLL_TIMEOUT_SECS` | How long the agent blocks on `wait_for_message` per turn (the universal poll path). `0` disables polling for push-only mode (Claude Code launched with `--dangerously-load-development-channels server:molecule`). Above 60 clamps to 60. | `2` |
Skills are surfaced two places:
1. **Canvas Skills tab** — each skill renders as a chip with the name
2. **Peer agents calling `list_peers`** — they see `{name, skills: [...]}` for each peer, so other agents can route delegations to the right specialist instead of guessing from name alone
Example with all three set (Claude Code 2.1+ CLI form):
```bash
claude mcp add molecule -s user \
-e WORKSPACE_ID=<uuid> \
-e PLATFORM_URL=https://<tenant>.moleculesai.app \
-e MOLECULE_WORKSPACE_TOKEN=<token> \
-e MOLECULE_AGENT_NAME='Research Assistant' \
-e MOLECULE_AGENT_DESCRIPTION='Reads, summarises, cites.' \
-e MOLECULE_AGENT_SKILLS=research,summarisation,citations \
-- molecule-mcp
```
Or as the equivalent `~/.claude.json` entry:
```json
{
"mcpServers": {
"molecule": {
"type": "stdio",
"command": "molecule-mcp",
"env": {
"WORKSPACE_ID": "<uuid>",
"PLATFORM_URL": "https://<tenant>.moleculesai.app",
"MOLECULE_WORKSPACE_TOKEN": "<token>",
"MOLECULE_AGENT_NAME": "Research Assistant",
"MOLECULE_AGENT_DESCRIPTION": "Reads, summarises, cites.",
"MOLECULE_AGENT_SKILLS": "research,summarisation,citations"
}
}
}
}
```
A peer agent's `list_peers()` call would then surface this workspace
as `Research Assistant — skills: [research, summarisation, citations]`,
which it can use to route a research task without first asking "what
can you do?".
## Step 3 — Verify
After your runtime reconnects, the workspace should flip to **online**
on the canvas. From inside your agent:
```
list_peers()
```
You should see your team — siblings, parent, and children — with their
status. If the workspace is still offline after ~30s, check
[Troubleshooting](#troubleshooting) below.
## Tools exposed
| Tool | What it does |
|---|---|
| `list_peers` | List workspaces this agent can A2A-message |
| `get_workspace_info` | Own identity (id, name, role, tier, parent) |
| `delegate_task` | Send a task to a peer and wait for the reply |
| `delegate_task_async` | Fire-and-forget delegation; result lands in inbox |
| `check_task_status` | Poll an async delegation |
| `wait_for_message` | Block until the next inbound A2A message arrives — the universal inbound-delivery primitive (see [Inbound delivery](#inbound-delivery-universal-poll-optional-push)) |
| `inbox_peek` / `inbox_pop` | Inspect / acknowledge queued inbound messages |
| `send_message_to_user` | Push a chat bubble to the user's canvas |
| `commit_memory` / `recall_memory` | Persistent KV (local / team / global scope) |
External runtimes can't accept inbound HTTP, so the wheel polls
`/activity?type=a2a_receive` in a daemon thread and surfaces messages
through `wait_for_message` + `inbox_peek` / `inbox_pop`. Use those
instead of waiting for an HTTP webhook — there isn't one.
### Inbound delivery: universal poll, optional push
Inbound messages reach the agent via one of two paths. The wheel
exposes both; which one fires depends on the host's capabilities.
Both paths converge on the same `inbox_pop` ack so dedup is automatic.
**Poll path (universal default — works on every spec-compliant MCP
client).** The wheel's `initialize` handshake includes an `instructions`
field telling the agent: *"At the start of every turn, before producing
your final response, call `wait_for_message(timeout_secs=N)` to check
for inbound messages."* Every MCP client surfaces `instructions` to
the agent's system prompt automatically, so Claude Code, Cursor, Cline,
OpenCode, hermes-agent, and codex all receive the polling contract
without any per-client wiring. The 2-second default is tuned for the
"peer A2A landed seconds before my turn started" common case; tune
via the `MOLECULE_MCP_POLL_TIMEOUT_SECS` env var
(see "Optional — declare your identity & capabilities" above).
**Push path (Claude Code with channel push enabled — strictly
better when available).** On top of the poll path, the wheel emits a
JSON-RPC notification (`notifications/claude/channel`) on every new
inbound message and declares the matching `experimental.claude/channel`
capability in `initialize`. Claude Code with channel push enabled
turns the notification into an inline `<channel source="molecule"
...>` synthetic user turn — zero agent-side polling cost, zero
per-turn stall.
**Today (research preview), Claude Code's channel push requires
either the `--dangerously-load-development-channels` launch flag OR
an entry on Claude Code's approved channel-server allowlist.** The
wheel ships the wire shape correctly, but a standard `claude` launch
without the flag silently drops the notification — which is why the
poll path has to be the floor.
Since Claude Code 2.1.x the flag takes a tagged allowlist, not a bare
switch. Pass each MCP server you want to push from as `server:<name>`
(matching the name you registered the server under in Claude Code's
config — `molecule` if you followed [Step 2](#claude-code) above):
```bash
claude --dangerously-load-development-channels server:molecule
```
Multiple entries are space-separated:
`server:molecule server:telegram`. A bare
`--dangerously-load-development-channels` (no value) is rejected with
`argument missing`; an untagged value (`molecule`) is rejected with
`entries must be tagged`. Easy way to confirm push is live: the
session header prints `Listening for channel messages from:
server:molecule`, and inbound canvas messages render inline as
`← molecule: <text>` instead of arriving via `inbox_peek`.
Set `MOLECULE_MCP_POLL_TIMEOUT_SECS=0` to disable polling entirely
when you're running Claude Code with the dev-channels flag and don't
want the per-turn stall. The instructions adapt automatically: with
polling disabled, the agent is told push is the only delivery path.
#### `<channel>` envelope attributes
Every inbound message — push or poll — carries the same metadata
shape. On the push path, attributes render inline as XML-style attrs
on the `<channel>` tag; on the poll path, the same fields appear in
the JSON returned by `inbox_peek` / `wait_for_message`. Either way,
the agent sees a consistent view.
| Attribute | When present | Description |
|---|---|---|
| `source` | always | Always `molecule` — distinguishes our channel from other registered servers (`telegram`, etc.). |
| `kind` | always | `canvas_user` (a human in the canvas chat) or `peer_agent` (another workspace's agent). Drives reply routing. |
| `peer_id` | always | Empty for `canvas_user`; the sender's workspace UUID for `peer_agent`. Use as `workspace_id` when calling `delegate_task` to reply. |
| `peer_name` | `peer_agent` only | The peer's display name (e.g. `ops-agent`) resolved from the platform registry. Absent on registry-lookup failure — the push still delivers. |
| `peer_role` | `peer_agent` only | The peer's declared role (e.g. `sre`, `coordinator`). Same registry source as `peer_name`; same graceful-degrade rule. |
| `agent_card_url` | `peer_agent` only | URL of the platform's discover endpoint for this peer. Fetch it if you need the peer's full capability list (skills, runtime, etc.). |
| `activity_id` | always | The inbox row ID. **Pass it to `inbox_pop` after handling** so the message isn't re-delivered on the next push or poll cycle. |
| `ts` | always | ISO-8601 timestamp of when the message landed in the platform's activity log. |
`peer_name` and `peer_role` are added by the wheel via a TTL'd
registry lookup keyed on `peer_id`. Cache TTL is 5 minutes — long
enough that a busy multi-peer chat doesn't hit the registry on every
push, short enough that role/name renames propagate within a single
agent session. Lookup failure is silent: the attributes are simply
absent and the push delivers anyway, so a registry stall can never
block inbound messages.
`agent_card_url` is constructed deterministically from `peer_id`, so
it's present even if the registry is down. The agent can hit it
later to enumerate the sender's capabilities once the registry is
back up.
Worked push example for a `peer_agent` arrival:
```
<channel source="molecule" kind="peer_agent"
peer_id="11111111-2222-3333-4444-555555555555"
peer_name="ops-agent" peer_role="sre"
agent_card_url="https://platform.example.com/registry/discover/11111111-2222-3333-4444-555555555555"
activity_id="act-742" ts="2026-05-01T12:34:56Z">
Can you check the deploy status for the canary?
</channel>
```
| Client | Push path | Poll path |
|---|---|---|
| Claude Code with `--dangerously-load-development-channels server:molecule` | ✅ inline `← molecule:` tag | ✅ also works |
| Claude Code (standard launch) | ❌ silently dropped | ✅ via instructions |
| Cursor / Cline / OpenCode / codex | ❌ method ignored | ✅ via instructions |
| hermes-agent | ❌ method ignored | ✅ naturally polls every cycle |
### MCP spec compliance
The wheel speaks MCP protocol version **2024-11-05** over stdio
JSON-RPC. It declares the standard `tools` capability plus the
`experimental.claude/channel` capability for the optional push path
(see [Inbound delivery](#inbound-delivery-universal-poll-optional-push)).
It implements the standard request methods and nothing client-specific:
| MCP method | Behavior |
|---|---|
| `initialize` | Echoes `protocolVersion: "2024-11-05"`, `serverInfo`, declares `tools` + `experimental.claude/channel` capabilities, returns the dual-path delivery `instructions` |
| `notifications/initialized` | No-op (no response — per spec) |
| `tools/list` | Returns all exposed tools in one response (no pagination cursor — surface is small) |
| `tools/call` | Dispatches by name, returns `content: [{ type: "text", text: ... }]` |
| _(unknown method)_ | Returns JSON-RPC error code `-32601` (Method not found) |
The push-UX notification (`notifications/claude/channel`) is the only
non-standard method emitted, and it's a one-way notification — clients
that don't handle it discard it per JSON-RPC semantics. The poll path
(via the standard `instructions` field) carries delivery for those
clients, so no part of the wheel's tool surface depends on a client
recognizing the notification.
This means **any spec-compliant MCP client** can drive the wheel:
Claude Code, Cursor, Cline, OpenCode, hermes-agent, or anything else
that opens an MCP stdio connection. If your client speaks MCP, it
speaks the wheel.
## Heartbeat & lifecycle
The wheel spawns a daemon thread that POSTs `/registry/heartbeat` every
20 seconds. Your runtime stays `online` on the canvas as long as that
heartbeat lands.
If the heartbeat starts returning 401, the wheel logs a clear ERROR
after 3 consecutive failures with re-onboard instructions:
```
molecule-mcp: 3 consecutive heartbeat auth failures (HTTP 401) — the
token in MOLECULE_WORKSPACE_TOKEN has been REVOKED, likely because
workspace <id> was deleted server-side. The MCP server is still running
but every platform call will fail. Regenerate the workspace + token
from the canvas (Tokens tab), update your MCP config, and restart your
runtime.
```
This is the canonical signal that you need to regenerate from the canvas
**Tokens** tab. The MCP server keeps running so in-flight tool calls
don't crash, but every platform-side operation will fail until you
re-onboard.
## Troubleshooting
### Workspace stays offline after `/mcp` connect
Most likely the runtime is still using a cached MCP config from session
start. Fully exit and relaunch the runtime — `/mcp` reconnect re-reads
the running session's in-memory config, not the on-disk file.
### `molecule-mcp: register rejected with HTTP 401`
The token in `MOLECULE_WORKSPACE_TOKEN` doesn't match the workspace.
Regenerate from the canvas Tokens tab.
### `Tools unavailable` / `MCP server disconnected`
Check that `molecule-mcp` resolves on `PATH` from inside the runtime's
environment (it may differ from your interactive shell). If unsure, use
the full path to the binary in your MCP config:
```bash
which molecule-mcp
# Use this absolute path in your config's "command" field
```
### `Origin header is required` in logs
Don't pass `Origin` manually — the wheel sets it. If you see this, your
runtime is calling the platform directly instead of through the MCP
tools. Use the tools (`delegate_task`, `send_message_to_user`, etc.)
rather than hand-rolling HTTP calls.
### Tools call returns 401 / `workspace not found` after working before
The workspace was probably deleted from the canvas (or via DELETE
`/workspaces/:id`). Deleting a workspace revokes its token immediately,
even if the workspace card still appears with a "removed" badge for a
short window. The MCP server itself keeps running, so tool listing
still succeeds, but every platform call fails.
Regenerate from the canvas **Tokens** tab — a deleted workspace can't
be brought back; you'll get a new workspace + token pair. Update your
MCP config and restart your runtime.
### `Workspace <id> was deleted on the platform...` from `get_workspace_info`
Since [#2429](https://github.com/Molecule-AI/molecule-core/pull/2449),
`GET /workspaces/:id` returns **410 Gone** (not 200 + `status:"removed"`)
when the workspace has been deleted. The MCP wheel's `get_workspace_info`
tool surfaces this as a tailored error message:
```
Workspace <id> was deleted on the platform at <removed_at>.
Regenerate workspace + token from the canvas → Tokens tab.
```
This is the **startup-time** counterpart to the heartbeat-401 escalation
above. If you see it within seconds of starting your runtime (rather
than after ~60s of heartbeat failures), the workspace was already gone
when you connected — regenerate as instructed.
Audit-trail tools that intentionally want to inspect a removed workspace's
metadata (admin dashboards, "show me deleted workspaces" tooling) can
opt back into the legacy 200 + body shape via
`GET /workspaces/<id>?include_removed=true`.
### `claude mcp list` shows the new config but tools still 401
`/mcp` reconnect re-spawns the **cached** MCP config from session
start, not the latest on-disk config. After editing `claude mcp add`
or your `~/.cursor/mcp.json`, fully exit and relaunch the runtime —
not just `/mcp`.
A quick way to confirm: `ps aux | grep molecule-mcp` and check the
PID hasn't changed across `/mcp` reconnects. If the same PID stays
alive, the runtime is still using the old config.
### `claude mcp add` rejects the install command on Claude Code 2.1+
Two common shapes from older docs trip the 2.1+ parser:
- `claude mcp add molecule -s user -- env VAR=val molecule-mcp` — works
but lands as `command: "env"` with positional args, which surprises
some MCP clients on older 2.1.x patch builds.
- `claude mcp add molecule -e VAR=val molecule-mcp` (missing `--`) — the
CLI parses `molecule-mcp` as a flag value, not a command, and either
errors or silently registers nothing.
Use the `-e` form **with** `--` (see [Step 2](#claude-code)), or skip the
CLI entirely and write the JSON shape into `~/.claude.json` directly.
The on-disk shape is the source of truth and not version-sensitive.
### `command not found: molecule-mcp` from inside the runtime
The runtime's `PATH` may differ from your interactive shell — common
on macOS where `~/Library/Python/3.x/bin` is added to login shells but
not to GUI-launched apps. Use the absolute path in your MCP config:
```bash
which molecule-mcp
# /Users/you/Library/Python/3.13/bin/molecule-mcp
```
Then point `command` at that absolute path in `claude mcp add` /
`.cursor/mcp.json` / `mcp_servers.yaml`.
### `error: option '--dangerously-load-development-channels <servers...>' argument missing`
You're on Claude Code 2.1.x or later. The flag changed from a bare
switch to an allowlist that takes tagged entries. See
[Inbound delivery](#inbound-delivery-universal-poll-optional-push) for
the right form — short answer:
```bash
claude --dangerously-load-development-channels server:molecule
```
### `--dangerously-load-development-channels entries must be tagged: molecule`
The flag value needs the `server:` (or `plugin:`) prefix. Pass
`server:molecule` (the registered MCP server name), not bare
`molecule`.
### `Control request timeout: initialize` from the workspace agent
This is the symptom of forwarding the dev-channels flag to a nested
`claude` CLI through the `claude-agent-sdk` with the wrong shape. If
you embed the wheel inside an SDK-driven agent (e.g. the claude-code
workspace template's `claude_sdk_executor.py`), pass the tagged value
through `extra_args`:
```python
ClaudeAgentOptions(
...,
extra_args={"dangerously-load-development-channels": "server:molecule"},
)
```
The SDK forwards `extra_args` keys as `--<key> <value>` to the spawned
CLI. Passing `None` renders as a bare switch and the post-2.1.x CLI
rejects it with `argument missing`, which surfaces upstream as
`Control request timeout: initialize` (the SDK never gets a response
to its initialize control message).
## When to use this vs. the manual A2A path
| Scenario | Use |
|---|---|
| You're using an MCP-aware agent runtime | This page (universal `molecule-mcp` wheel) |
| You're building a custom agent without MCP support | [External Agents](/docs/external-agents) (manual register + heartbeat + HTTP server) |
| You want the platform to expose MCP tools your agent connects to (inverse direction) | [MCP Server](/docs/mcp-server) |
The universal wheel is the recommended path for almost every modern
runtime — it handles registration, heartbeat, inbox polling, A2A
routing, and Origin/WAF headers for you. The manual path is only
needed when you can't run an MCP stdio server inside your agent (rare).
