What

Fixes the live #3159 failure: a non-claude-code concierge (codex/hermes) never got create_workspace. MCPServerAdaptor stored its runtime arg but always wrote /configs/.claude/settings.json — a file those runtimes never read — so the molecule-platform management MCP was never wired and the RCA#2970 online gate fail-closed the concierge offline.

Implements the runtime-side work for docs/design/rfc-platform-mcp-as-plugin.md (merged on molecule-core main) using the recommended MCP-wiring PORT (lego, not an if runtime == ladder).

Changes

• protocol.py — add register_mcp_server(name, spec) to InstallContext, alongside register_tool/register_subagent.
• adapter_base.py — back it with BaseAdapter.register_mcp_server_hook (DEFAULT = today's claude deep-merge into .claude/settings.json) + mcp_settings_path() + management_mcp_present() (the gate probe). Per-runtime template adapters override these.
• mcp_render.py (new) — pure per-runtime renderers. claude (settings.json) and codex (~/.codex/config.toml [mcp_servers]) implemented CONCRETELY; gemini-cli + hermes are honest NotImplementedError stubs (native format unverified — see TODOs).
• builtins.py — MCPServerAdaptor.install parses the mcpServers descriptor (mcp-servers.json | settings-fragment.json) and calls ctx.register_mcp_server per entry; _merge_settings_fragment no longer touches mcpServers (the PORT owns them). A privileged-plugin install on a runtime with no renderer fails LOUDLY (PrivilegedPluginInstallError) rather than booting a capability-less concierge.
• platform_agent_identity.py — mcp_server_present() asks the active adapter via a registered probe (register_mcp_present_probe) instead of unconditionally reading SETTINGS_PATH; claude settings.json stays the DEFAULT when no probe is registered (baked-binary path + every existing test unchanged).
• main.py — wires the probe from the resolved adapter at boot.
• contract — mcp-plugin-delivery.contract.json is now PER-RUNTIME (claude/codex implemented, gemini/hermes todo-unverified) + documents the PORT.
• tests — per-runtime render matrix (RFC §5b Addition 1) INCLUDING the explicit "codex -> config.toml and NOT .claude/settings.json" assertion that would have caught this bug; PORT round-trip tests; MCPServerAdaptor routing tests; skipped stubs for gemini/hermes.

TODO stubs left (format unverified)

• gemini-cli and hermes renderers raise NotImplementedError with skipped render-matrix tests, rather than guessing a config a concierge silently can't read (the exact #3159 failure mode). Implement once each format is pinned against a live runtime.

Tests

Full pytest suite green except one PRE-EXISTING failure unrelated to this change (test_executor_helpers.py::test_extract_attached_files_accepts_real_strings_unaffected, also red on main). All MCP/identity/adaptor/contract suites pass (99 passed, 2 skipped in the targeted set).

fix(runtime#3159): deliver management MCP runtime-agnostically via an MCP-wiring PORT ... 7cdfdbcc35

A non-claude-code concierge (codex/hermes) never got create_workspace: the
MCPServerAdaptor stored its `runtime` arg but always wrote
/configs/.claude/settings.json, a file those runtimes never read, so the
molecule-platform management MCP was never wired and the RCA#2970 online gate
fail-closed the concierge.

Replace the hard-coded "always merge into Claude settings.json" path with a
runtime-agnostic MCP-wiring PORT (lego, not an `if runtime ==` ladder):

- protocol.py: add `register_mcp_server(name, spec)` to InstallContext,
  alongside register_tool/register_subagent.
- adapter_base.py: back it with BaseAdapter.register_mcp_server_hook (default =
  today's claude deep-merge into .claude/settings.json) + mcp_settings_path()
  + management_mcp_present() (the gate probe). Per-runtime template adapters
  override these.
- mcp_render.py (new): pure per-runtime renderers — claude (settings.json) +
  codex (~/.codex/config.toml [mcp_servers]) implemented concretely; gemini-cli
  + hermes are honest NotImplementedError stubs (native format unverified).
- builtins.py: MCPServerAdaptor.install now parses the mcpServers descriptor
  (mcp-servers.json | settings-fragment.json) and calls ctx.register_mcp_server
  per entry; the claude layer's _merge_settings_fragment no longer touches
  mcpServers (the PORT owns them). A privileged-plugin install on a runtime with
  no renderer fails loudly (PrivilegedPluginInstallError) rather than booting a
  capability-less concierge.
- platform_agent_identity.py: mcp_server_present() asks the active adapter via a
  registered probe (register_mcp_present_probe) instead of unconditionally
  reading SETTINGS_PATH; claude settings.json stays the default when no probe is
  registered (baked-binary path + every existing test unchanged).
- main.py: wires the probe from the resolved adapter at boot.
- contract: mcp-plugin-delivery.contract.json is now per-runtime (claude/codex
  implemented, gemini/hermes todo-unverified) + documents the PORT.
- tests: per-runtime render matrix (RFC §5b Addition 1) incl. the explicit
  "codex -> config.toml and NOT .claude/settings.json" assertion that would have
  caught this bug; PORT round-trip tests; MCPServerAdaptor routing tests; skipped
  stubs for gemini/hermes.

REQUEST_CHANGES on runtime#172 head 7cdfdbcc35.

Correctness blocker: the claimed concrete Codex path is not actually wired into the active adapter hook. BaseAdapter.register_mcp_server_hook() still unconditionally imports/calls render_claude_settings(Path(self.mcp_settings_path(config)), name, spec), and this PR does not add a Codex adapter override that calls render_codex_config() or overrides management_mcp_present() to parse ~/.codex/config.toml. The tests cover the pure Codex renderer and a mocked ctx.register_mcp_server, but not the real install path for a Codex adapter.

So a codex concierge can still route MCPServerAdaptor.install() through the base hook and write the management MCP into .claude/settings.json, the same failure mode #3159 is meant to fix. Please wire the concrete Codex adapter hook/probe into the actual runtime adapter path and add an integration-style test that installs the privileged MCP plugin through a Codex adapter/config and asserts ~/.codex/config.toml contains molecule-platform, .claude/settings.json is not created for that MCP, and the registered gate probe reports present from the Codex config.

CI is green, and the port/descriptors are a good direction, but this head does not yet exercise/fix the live Codex path.

REQUEST_CHANGES: I concur with CR2's blocker, and there are additional completeness issues for the same fix pass.

1. molecule_runtime/adapter_base.py:444 still makes BaseAdapter.register_mcp_server_hook() call render_claude_settings(...) unconditionally, and molecule_runtime/adapter_base.py:468 still parses the same JSON shape in management_mcp_present(). The PR adds render_codex_config() in molecule_runtime/mcp_render.py:142, but no production Codex adapter override is added here. The only Codex hook round-trip is a fake _CodexLikeAdapter inside tests/test_mcp_plugin_delivery_contract.py:344, so a real Codex concierge can still route the management MCP through the base hook into .claude/settings.json instead of Codex config.toml.

2. Hermes/Gemini are explicitly left unwired: molecule_runtime/mcp_render.py:172 and molecule_runtime/mcp_render.py:193 raise NotImplementedError, while the contract marks them todo-unverified. That is honest fail-closed behavior, but it does not complete the runtime-agnostic MCP-delivery fix promised by #3181/#3185 for every non-Claude runtime. Either implement the real Hermes/Gemini adapter render+probe path now, or narrow the PR/contract/gate to explicitly ship only Claude+Codex and ensure unsupported privileged concierges cannot be scheduled as online-capable.

3. Coverage gap: add tests against the actual adapter class/module used by Codex (and Hermes/Gemini if supported), not only synthetic test subclasses. The regression test should exercise install_plugins_via_registry() with molecule-platform-mcp on that runtime and assert the native config file is written, .claude/settings.json is not written, and management_mcp_present() reads the same native file.

5-axis summary: correctness is blocked because renderer code is not connected to the active runtime adapter path; robustness/security are blocked because a platform concierge can still be miswired or left unsupported without a production adapter proof; performance is not a concern; readability of the port is reasonable but currently overstates completeness. Please wire the real runtime adapters/probes and make the contract/tests match the actually supported runtime set.

Maintaining REQUEST_CHANGES 13467 on the live head 7cdfdbcc35. The head has not moved since the RC.

Re-check result: the intended fail-loud gemini/hermes stubs are fine, and the identity probe fallback preserves the Claude/baked-binary behavior. The blocker remains specifically the live Codex path: this head defines render_codex_config(), but the actual BaseAdapter.register_mcp_server_hook() still calls render_claude_settings(...), and I still do not see a concrete Codex adapter override/probe that routes a real Codex install through render_codex_config() and parses ~/.codex/config.toml. The tests cover the pure renderer and mocked port routing, but not an actual Codex adapter install/probe path.

So my prior RC is not addressed on this live head. Required fix remains: wire the concrete Codex adapter hook/probe into the active runtime adapter path, and add an integration-style test that installs the privileged MCP plugin through a Codex adapter/config and proves ~/.codex/config.toml contains molecule-platform, .claude/settings.json is not used for that MCP, and the identity gate reports present via the Codex config.

REQUEST_CHANGES: re-review on current live head 7cdfdbcc. My prior RC is only partly reconciled.

What is resolved/acceptable by design: the identity gate wiring in main.py preserves the baked-binary/Claude fallback, and the explicit Gemini/Hermes NotImplementedError renderers are acceptable as fail-loud safety for unsupported privileged concierges. I am no longer treating those stubs as a defect if the intended supported scope for this PR is Claude+Codex only and unsupported runtimes fail closed.

Remaining blocker: the live head still does not prove or wire the production Codex adapter path. BaseAdapter.register_mcp_server_hook() still renders via render_claude_settings() into <config_path>/.claude/settings.json (molecule_runtime/adapter_base.py:444-465), and management_mcp_present() still parses the same JSON shape (adapter_base.py:468-495). The Codex renderer exists (molecule_runtime/mcp_render.py:142-165), but the only Codex hook/probe proof I see is the synthetic _CodexLikeAdapter test class in tests/test_mcp_plugin_delivery_contract.py:344-384; no real Codex adapter/module in this repo overrides the hook/probe, and no test drives install_plugins_via_registry() through the actual Codex adapter class that production boots.

Required fix: either wire the real Codex adapter to override mcp_settings_path, register_mcp_server_hook, and management_mcp_present using render_codex_config, or make BaseAdapter dispatch by self.name() for Codex safely. Add a regression test that instantiates the actual production Codex adapter path, installs the privileged molecule-platform-mcp plugin via install_plugins_via_registry(), asserts ~/.codex/config.toml gets mcp_servers.molecule-platform, asserts .claude/settings.json is not written for Codex, and asserts the active identity probe returns true from that Codex-native file.

CI note: visible Gitea contexts on this head are green. I cannot confirm the reported 843-pass/1-pre-existing-fail from the status API alone; the blocking issue is code-path coverage/completeness, not current CI color.

fix(runtime#3159): close PORT in the PRODUCTION path — default hook dispatches per-runtime ... f8fee57b91

Addresses CR2 #13467 + Researcher #13468 review: the PORT was right but the
production path still rendered Claude settings.json for every runtime, so a REAL
codex concierge kept writing the management MCP to .claude/settings.json (the
flaw persisted). Make the runtime CLOSE it end-to-end, no per-template override.

- mcp_render.py: add the per-runtime DISPATCH layer — render_for_runtime /
  mcp_settings_path_for / management_mcp_present_for keyed on the normalized
  runtime name (claude_code -> .claude/settings.json; codex -> ~/.codex/
  config.toml parsed via stdlib tomllib; gemini/hermes -> fail-loud stub).
  Unmapped runtime falls back to claude (base runtime).
- adapter_base.py: BaseAdapter.register_mcp_server_hook / mcp_settings_path /
  management_mcp_present now DISPATCH on self.name() through mcp_render. A codex
  adapter that overrides ONLY name() gets codex rendering from the DEFAULT hook
  via the normal install_plugins_via_registry path — no per-template override.
- plugins_registry/__init__.py: resolve() now defaults an mcpServers-shaped
  plugin to MCPServerAdaptor (AdaptorSource.MCP_SERVER) for ANY runtime, so the
  molecule-platform-mcp plugin resolves the runtime-agnostic adaptor on codex
  without shipping adapters/codex.py — the missing link that made the e2e path
  actually render codex config.toml.
- tests: replace the synthetic _CodexLikeAdapter (which overrode the hook) with
  no-override adapters that differ ONLY in name(), and add END-TO-END tests
  through the real install_plugins_via_registry path asserting codex writes
  ~/.codex/config.toml and NOT .claude/settings.json (and the symmetric claude
  case + the hermes fail-loud-for-privileged case).
- contract: document the default dispatch + resolver default.

hermes/gemini stay deliberate fail-loud NotImplementedError stubs (safe: no
silently capability-less concierge); implement once the native format is
verified against a live runtime.

APPROVED on runtime#172 head f8fee57b91.

Re-review against prior RC 13467: addressed. The base register_mcp_server_hook() now dispatches through mcp_render.render_for_runtime(self.name(), ...), with Codex mapped to ~/.codex/config.toml and management_mcp_present_for() parsing the Codex TOML table. The real/default-adapter regression tests now exercise a no-override Codex adapter through the production install path and assert Codex config is written, .claude/settings.json is not used for the MCP, and the gate probe reports present from Codex config. Claude/baked-binary fallback behavior is preserved, and gemini/hermes remain intentional fail-loud stubs for privileged MCP install rather than silently booting a capability-less concierge.

CI status is green on this head. The one full-suite failure noted in the PR body is documented as pre-existing/unrelated; the targeted MCP/identity/adaptor/contract coverage is present and directly addresses the prior gap.

APPROVED on f8fee57b.

5-axis review: correctness looks addressed. The default BaseAdapter hook now routes through the runtime MCP-rendering port (render_for_runtime(self.name(), ...)) instead of hard-coding Claude settings, so a Codex runtime writes management MCP config to ~/.codex/config.toml. Robustness/security are acceptable: Gemini/Hermes remain explicit fail-loud stubs for privileged MCP delivery rather than silently installing into the wrong shape, while Claude/baked-binary fallback behavior is preserved. Performance impact is negligible and readability is improved by centralizing runtime path/render/present dispatch in mcp_render.py.

The prior RC is addressed: the new tests exercise the production install_plugins_via_registry path for a Codex-named adapter, assert Codex config.toml is written, assert .claude/settings.json is not written, and verify the active-adapter identity probe sees the management MCP. Visible CI on the current head is green.
