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.

Operational and one-off scripts for molecule-core. Most are self-documenting — see the header comments in each file.
RFC #2251 coordinator task-bound harnesses
There are three related scripts; pick the right one:
| Script | Purpose | Targets |
|---|---|---|
measure-coordinator-task-bounds.sh |
Canonical v1 harness for the RFC #2251 / Issue 4 reproduction. Provisions a PM coordinator + Researcher child via claude-code-default + langgraph templates, sends a synthesis-heavy A2A kickoff, observes elapsed time + activity trace. |
OSS-shape platform — localhost or any /workspaces-shaped endpoint. Has tenant/admin-token guards for non-localhost runs. |
measure-coordinator-task-bounds-runner.sh |
Generalised runner for the same measurement contract but with arbitrary template + secret + model combinations (Hermes/MiniMax, etc.). Useful for cross-runtime variants without modifying the canonical harness. | Same as above (local or SaaS via MODE=saas). |
measure-coordinator-task-bounds.sh (in molecule-controlplane) |
Production-shape variant that bootstraps a real staging tenant via POST /cp/admin/orgs, then runs the same measurement against <slug>.staging.moleculesai.app. |
Staging controlplane only — refuses to run against production. |
See reference_harness_pair_pattern (auto-memory) for when to use which
and the cross-repo design rationale.
Common safety pattern across all three
- Cleanup trap on EXIT/INT/TERM auto-deletes provisioned resources.
DRY_RUN=1prints plan + auth fingerprint, exits before any state mutation. Run this before pointing at staging or any shared infrastructure.- Non-target guard refuses arbitrary endpoints (the controlplane
variant is locked to
staging-api.moleculesai.app; the OSS variant requires explicit auth + tenant scoping for non-localhost PLATFORM). - Cleanup failures emit
cleanup_*_failedevents with remediation hints; no silenced curl. ADMIN_TOKEN expiring mid-run surfaces as a structured event rather than a silent leak.
Activity trace caveat
If activity_trace.raw == "<endpoint_unavailable>", the per-workspace
/activity endpoint isn't wired on the target build — the bound
measurement is INCONCLUSIVE on the platform-ceiling question. Either
wire the endpoint or replace with the equivalent Datadog query. Note
that /activity accepts a since_secs query parameter; see the
endpoint handler for the supported range.
Other scripts
cleanup-rogue-workspaces.sh— emergency teardown for leaked workspaces. Prompts for confirmation. Pair with the harnesses if a cleanup trap fails (seecleanup_*_failedevents).canary-smoke.sh— quick smoke test for canary releases.dev-start.sh— local-dev platform bring-up.
The rest are self-documenting in their header comments.
