Co-op Anything MCP
Capped at 90: 2 of 3 real tool calls passed in our test; the tests add up to 95. Why scores are capped
Test points add up to 95; the score is capped at 90 because not every real tool call passed. Not a quality or security rating. Why scores are capped

Git-only (pinned)
Git-only (pinned): installed from GitHub commit a71be2ca706c5d6e4edc02f957e0081fd2742e43 (git clone https://github.com/cranebeaker/coop-anything && git -C coop-anything checkout <sha> && python3 coop-anything/tools/mcp/coop_mcp.py), install scripts off. Initialize and tools/list worked (9 tools). Stand-alone Python script tools/mcp/coop_mcp.py from the cranebeaker/coop-anything repo (a directory and playbook for game co-op mods), run with python3. Real calls (no credentials): list_docs and read_playbook {page:'triage'} returned repo content. search_directory failed with "PyYAML missing: pip install pyyaml": the script needs PyYAML for its directory search, but the repo declares no dependency, so a plain `python tools/mcp/coop_mcp.py` (the repo's .mcp.json) lacks it. detect_engine/game_identity need a local game install and were not called. Not listed on Glama when tested.
Tool-call test (2026-11-09, direct MCP stdio client, no LLM): pass. 2 of 3 read-only calls passed; search_directory failed (needs PyYAML, which the repo does not declare). Evidence: local test run, Nov 9, 2026.
Transport (tested 2026-11-09): stdio

What we tested and what we didn't
Tested on 2026-11-09
- Install from the registry
- We connected with no credentials and asked for its tool list: it listed 9 tools (Method details: MCP
initializethentools/list) - Maintenance signals (last push, archived/deprecated status)
- Docs (README length, install and config example)
- License (OSI-approved or not)
- Token cost (estimate)
Not tested
- Security: not audited (no code review, no permission or data-flow analysis)
- Real tasks (no functional task runs yet)
- Behaviour with real credentials or a real account
- Performance, rate limits or load
- Correctness of results beyond the listed tasks
Methodology: how we test. A high score means it installs and responds, not that giving it access to your data carries no risk.
