feat(mcp): CODEC as MCP client (bidirectional) + 25-beat demo script#239
Merged
Conversation
…237) PR #237 (a harmless ruff version bump) went red on CI/smoke with two failures that have nothing to do with ruff — both pass in isolation and are pre-existing timing flakes: * test_deadline_timeout: `assert len(timeouts) == 1` saw 2. ask() is synchronous and finalizes exactly one timeout per call, so the extra event came from a background-threaded ask() in a NEIGHBOURING test finalizing late into this test's audit log (_log_event reads the log path live at write-time). Now scoped: count only emit/timeout events whose extra.pending_question_id is THIS test's qid. * test_round_trip: "notification not written". ask() writes the pending record and the notification as two separate writes; the test polled for the record then asserted on the notification, which can lag under load. Now polls for the notification too. Both are test-only changes; runtime code untouched. Verified: the two tests pass 10/10 under repeated runs; full suite 2497 passed.

…er beat Restores the full list I over-tightened, fixes status (Vision Mouse #7 = done; Pilot #14 = half-broken), and adds the 3 new beats: MCP client (#23, bidirectional with the MCP server #18), self-improve live (#24), Compare (#25). Each beat now carries an exact TRY/EXPECT so it doubles as the test sheet. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…(beat #23) CODEC already exposes its skills as an MCP *server* (Claude plugs into CODEC). This adds the other direction: CODEC reaches OUT to external MCP servers — the same public connectors Claude uses (Notion, GitHub, Linear, Stripe, Hugging Face, …) — and calls their tools. CODEC is now bidirectional MCP. - skills/mcp_connect.py: a bridge skill over fastmcp.Client (already a dependency — no new install). Servers declared in ~/.codec/mcp_servers.json, seeded on first use with a curated menu of popular servers (most ship disabled pending the operator's OAuth/API key — enabling is a one-line edit). Grammar: "list mcp" · "list tools on <server>" · 'call <server> <tool> {json}' · or any mention of a server → connect + list its tools. async fastmcp.Client is bridged to CODEC's sync skill contract via a fresh loop on a worker thread. Not exposed on CODEC's own outbound MCP server (SKILL_MCP_EXPOSE=False) so a remote client can't chain CODEC -> arbitrary third-party tools unattended. - Verified against a REAL public server: connected to huggingface.co/mcp and listed its live tools (hf_whoami, space_search, hub_repo_search, hf_fs, …). - 9 unit tests (fastmcp.Client faked — network-free): config seeding, list, call, disabled-server guard, bad-JSON, unknown-server, network-error. D-1 manifest regenerated (87 skills). ruff clean. Demo beat #23 (right after the MCP-server beat #18): "CODEC, connect to Notion and create a page" -> CODEC calls out to the external MCP.

Two things:
1. CODEC as an MCP client (demo beat #23). CODEC already serves its skills to Claude over MCP; this adds the reverse — CODEC connects out to external MCP servers (Notion, GitHub, Linear, Stripe, Hugging Face…) and calls their tools. Bidirectional MCP. Built on
fastmcp.Client(existing dep). Servers live in~/.codec/mcp_servers.json(seeded with a popular-server menu; enabling one is a one-line edit). Verified against a real server — connected tohuggingface.co/mcpand listed its live tools. 9 network-free tests, manifest regenerated.2. Corrected 25-beat
DEMO_SCRIPT.mdwith an exact TRY/EXPECT per beat (fixes Vision Mouse=done, Pilot=half-broken; adds MCP-client/self-improve/Compare).Also fixed the #237-blocking flake separately (PR #238, merged).
