What

The cross-repo durable prevention layer for the MCP tool-verb SSOT contract (core#3082). It resolves the ACTUAL tool manifest of the PUBLISHED @molecule-ai/mcp-server build (the build a concierge is actually delivered) and asserts it satisfies the contract's accepted verb union (required_tools ∪ transitional_tool_aliases). This is the layer that would have caught the staging stale-published-build degrade — a published build skewed away from the contract fails HERE, in core CI, BEFORE any tenant provisions a concierge against it.

It complements the in-repo Go contract test (checks core's own hand-written verb) and the producer-binding test in @molecule-ai/mcp-server (checks the producer SOURCE). Neither of those sees the PUBLISHED artifact; this does.

New files (no existing files modified)

• scripts/mcp-verb-manifest-check/check-published-mcp-manifest.mjs — loads an already-installed published build via an in-tree child harness that patches the ESM McpServer.prototype.tool to record registered tool names, builds the management-mode server, and asserts ⊇ contract. FAIL when no accepted verb is present (the staging degrade); WARN (non-fatal) when only a transitional alias carries the gate. Reads required_tools (+ transitional_tool_aliases); falls back to legacy required_tool.
• .gitea/workflows/mcp-verb-published-manifest.yml — installs the published package from the Gitea npm registry and runs the checker. Standalone soak-then-promote workflow (mirrors the contract-drift gate); a daily cron catches a newly-published skew even with no commit (the stale-build failure mode is time-, not commit-, dependent).

Does NOT touch contracts/mcp-plugin-delivery.contract.json, platform_agent.go, or registry.go — the verb-SSOT PR owns those.

New CI secret required

MCP_SERVER_READPKG_TOKEN — a Gitea token with read:package scope for the molecule-ai npm registry (the workflow installs the published package). Fail-closed on trusted contexts; soft-skip on fork PRs. Please provision this org/repo secret before promoting the workflow into branch protection.

Heads-up: this check FAILS against today's main — by design

Run against current origin/main (legacy required_tool: create_workspace) the check FAILS, because the published management build exposes provision_workspace, never create_workspace — i.e. it immediately surfaces the live contract↔producer mismatch core#3082 is fixing. It goes green once the contract is corrected to provision_workspace (the core verb-SSOT PR) OR a build exposing create_workspace is published. This is the gate doing its job, not a flake.

Enforcement proven locally (vs the real published 1.6.1 build, 41-tool manifest)

Contract under test	Result
required=[provision_workspace] (corrected)	OK (exit 0)
required=[create_workspace] only	FAIL (exit 1) — the staging stale-build catch
required=[create_workspace] + provision_workspace alias	OK + loud ::warning
current origin/main legacy required_tool=create_workspace	FAIL (exit 1) — surfaces the live mismatch

Dependency

Depends on the core verb-SSOT PR (feat/3082-mcp-verb-ssot-contract) landing required_tools: ["provision_workspace"] (+ optional transitional_tool_aliases) in the contract. The checker's legacy fallback keeps it safe to land before/after.

Review

Requesting 2 genuine pool reviews before merge. Do not merge until the core verb-SSOT PR corrects the contract (otherwise it lands red against main, as noted above) and MCP_SERVER_READPKG_TOKEN is provisioned.

ci(3082): checker — published mcp-server manifest ⊇ contract required verbs ... a914662142

Resolves the ACTUAL tool manifest of the PUBLISHED @molecule-ai/mcp-server
build (management mode) via an in-tree child harness that patches the ESM
McpServer to record registered tools, and asserts it satisfies the
contract's accepted verb union. FAILs when no accepted verb is present
(the staging stale-build degrade); WARNs (non-fatal) when only a
transitional alias carries the gate. Reads required_tools (+ aliases) with
a fallback to legacy required_tool. Deliberately introspects the PUBLISHED
package, never a source build (main lacks the management-mode split).

ci(3082): workflow — resolve published mcp-server manifest and assert vs contract ... 7619a72205

Installs the published @molecule-ai/mcp-server from the Gitea npm registry
(read:package via MCP_SERVER_READPKG_TOKEN) and runs the checker.
Standalone soak-then-promote workflow (mirrors the contract-drift gate);
daily cron catches a newly-published skew with no commit. Fail-closed on
trusted contexts, soft-skip on fork PRs.

APPROVED on head 7619a72205.

5-axis/RCA review: this adds the missing published-artifact guard rather than another source-only check. The workflow installs the published @molecule-ai/mcp-server package from Gitea npm with a read:package token, runs a local harness in management mode, records the actual registered tool names, and fails if the published manifest exposes none of the contract-accepted verbs. The script fails closed on missing contract fields, zero-tool introspection, server-name mismatch, and no accepted verb; it warns but does not fail when only a transitional alias is present, which matches the staged deprecation model. Secret handling is appropriate for this CI context: the read-package token is only in .npmrc in a temp dir and is required only on trusted contexts; fork PRs soft-skip because they cannot receive the secret.

Status note: the manifest check is expected to be red against current main/published state until #3280/producer publication sequencing catches up, and the missing MCP_SERVER_READPKG_TOKEN is an ops prerequisite. Code is sound on merits.

Reviewed head 7619a72205. APPROVED on code merits. The published-manifest checker resolves the real published mcp-server package, captures registered management-mode tools via SDK monkeypatching, and validates the contract verbs; it supports both plural required_tools and legacy singular required_tool. Trusted missing MCP_SERVER_READPKG_TOKEN fail-closes, fork/no-secret paths soft-skip without exposing tokens. Expected red until #3280 and the read:package secret are in place.
