Local-model readiness

Schema context cost: ~1,824 tokens for 9 tools (8,604 bytes) · about 22% of an 8k context. Method: tiktoken cl100k_base over compact JSON of name+description+inputSchema (approximate).

Small-model friendly (schema heuristic, not a model result): unknown.

What we tested and what we didn't

Tested on 2026-10-27

  • Install from the registry
  • We connected with no credentials and asked for its tool list: it listed 9 tools (Method details: MCP initialize then tools/list)
  • Maintenance signals (last push, archived/deprecated status)
  • Docs (README length, install and config example)
  • License (OSI-approved or not)
  • Tool-schema 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 it is safe to give it access to your data.

Known security issues
