feat(mcp): notifications/claude/channel for push-feel inbox UX
Adds a notification seam to the universal molecule-mcp wheel so push- notification-capable MCP hosts (Claude Code today; any compliant client tomorrow) get inbound A2A messages as conversation interrupts instead of having to poll wait_for_message / inbox_peek. Wire-up: - inbox.py: module-level _NOTIFICATION_CALLBACK + set_notification_callback() Fires from InboxState.record() AFTER lock release, with same dict shape inbox_peek returns. Best-effort — a raising callback never prevents the message from landing in the queue. - a2a_mcp_server.py: _build_channel_notification() pure helper + bridge wiring in main() that schedules notifications via asyncio.run_coroutine_threadsafe (poller is a daemon thread, MCP loop is asyncio). - Method name 'notifications/claude/channel' matches the contract documented in molecule-mcp-claude-channel/server.ts:509. - wheel_smoke.py: pin set_notification_callback as a published name, same regression class as the 0.1.16 main_sync incident. Pollers (wait_for_message / inbox_peek) keep working unchanged for runtimes without notification support. Tests: 6 new in test_inbox.py (callback fires once on record, dedupe short-circuits before fire, raising cb doesn't break inbox, set/clear semantics), 5 new in test_a2a_mcp_server.py (method name pin, content mapping, meta routing, no-id JSON-RPC notification spec, missing- field tolerance). All 59 combined tests pass. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

feat(workspace-runtime): add inbox polling for standalone molecule-mcp path
The universal MCP server (a2a_mcp_server.py) was outbound-only — agents
in standalone runtimes (Claude Code, hermes, codex, etc.) could
delegate, list peers, and write memories, but never observed the
canvas-user or peer-agent messages addressed to them. This blocked
"constantly responding" loops without forcing operators back onto a
runtime-specific channel plugin.
This PR closes the inbound gap with a poller-fed in-memory queue and
three new MCP tools:
- wait_for_message(timeout_secs?) — block until next message arrives
- inbox_peek(limit?) — list pending messages (non-destructive)
- inbox_pop(activity_id) — drop a handled message
A daemon thread polls /workspaces/:id/activity?type=a2a_receive every
5s, fills the queue from the cursor (since_id), and persists the cursor
to ${CONFIGS_DIR}/.mcp_inbox_cursor so a restart doesn't replay backlog.
On 410 (cursor pruned) we fall back to since_secs=600 for a bounded
recovery window. Activity-row → InboxMessage extraction mirrors the
molecule-mcp-claude-channel plugin's extractText (envelope shapes #1-3
+ summary fallback).
mcp_cli.main starts the poller alongside the existing register +
heartbeat threads. In-container runtimes (which have push delivery via
canvas WebSocket) skip activation, so inbox tools return an
informational "(inbox not enabled)" message instead of double-delivery.

feat(workspace-runtime): expose universal MCP server to runtime=external operators
Ship the baseline universal MCP path that any external runtime (Claude
Code, hermes, codex, anything that speaks MCP stdio) can use, before
optimizing per-runtime channels. Today the workspace MCP server only
spins up inside the container; external operators have no way to call
the 8 platform tools (delegate_task, list_peers, send_message_to_user,
commit_memory, etc.) from outside.
Three additive changes:
1. **`platform_auth.get_token()` env-var fallback** — adds
`MOLECULE_WORKSPACE_TOKEN` as a fallback when no
`${CONFIGS_DIR}/.auth_token` file exists. File-first preserves
in-container behavior unchanged. External operators (no /configs
volume) now have a way to supply the token without faking the
filesystem layout.
2. **`molecule-mcp` console script** — adds a new entry point in the
published `molecule-ai-workspace-runtime` PyPI wheel. Operators run
`pip install molecule-ai-workspace-runtime`, set 3 env vars
(WORKSPACE_ID, PLATFORM_URL, MOLECULE_WORKSPACE_TOKEN), and register
the binary in their agent's MCP config. `mcp_cli.main` is a thin
validator wrapper — it checks env BEFORE importing the heavy
`a2a_mcp_server` module so a misconfigured first-run gets a friendly
3-line error instead of a 20-line module-level RuntimeError
traceback.
3. **Wheel smoke gate** — extends `scripts/wheel_smoke.py` to assert
`cli_main` and `mcp_cli.main` are importable. Same regression class
as the 0.1.16 main_sync incident: a silent rename or unrewritten
import here would break every external operator on the next wheel
publish (memory: feedback_runtime_publish_pipeline_gates.md).
Test coverage:
- `tests/test_platform_auth.py` — 8 new tests for the env-var fallback:
file-priority, env-fallback, whitespace handling, cache, header
construction, empty-env-as-unset.
- `tests/test_mcp_cli.py` — 8 new tests for the validator: each
required var separately, file-or-env satisfies token requirement,
whitespace-only env treated as missing, help mentions canvas Tokens
tab.
- Full `workspace/tests/` suite green: 1346 passed, 1 skipped.
- Local end-to-end: built wheel, installed in venv, ran `molecule-mcp`
with no env → friendly error; with env → MCP server starts.
Why now / why this shape: user redirect was "support the baseline
first so all runtimes can use, then optimize". A claude-only MCP
channel leaves hermes/codex/third-party operators broken on
runtime=external. This PR ships the runtime-agnostic baseline; per-
runtime polish (claude-channel push delivery, hermes-native
bindings) is a follow-up PR. PR #2412 fixed the partner bug where
canvas Restart silently revoked the operator's token — the two
together unblock the external-runtime story end-to-end.

refactor(ci): extract wheel smoke into shared script
publish-runtime.yml had a broad smoke (AgentCard call-shape, well-known
mount alignment, new_text_message) inline as a heredoc. runtime-prbuild-
compat.yml had a narrow inline smoke (just `from main import main_sync`).
Result: a PR could introduce SDK shape regressions that pass at PR time
and only fail at publish time, post-merge.
Extract the broad smoke into scripts/wheel_smoke.py and invoke it from
both workflows. PR-time gate now matches publish-time gate — same script,
same assertions. Eliminates the drift hazard of two heredocs that have
to be kept in lockstep manually.
Verified locally:
* Built wheel from workspace/ source, installed in venv, ran smoke → pass
* Simulated AgentCard kwarg-rename regression → smoke catches it as
`ValueError: Protocol message AgentCard has no "supported_interfaces"
field` (the exact failure mode of #2179 / supported_protocols incident)
Path filter for runtime-prbuild-compat extended to include
scripts/wheel_smoke.py so smoke-only edits get PR-validated. publish-
runtime path filter intentionally NOT extended — smoke-only edits should
not auto-trigger a PyPI version bump.
Subset of #131 (the broader "invoke main() against stub config" goal
remains pending — main() needs a config dir + stub platform server).
