Local-model readiness
Schema context cost: ~1,976 tokens for 17 tools (8,281 bytes) · about 24% 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.
Small-model task runs: Not yet tested.
What we tested and what we didn't
Tested on 2026-10-25
- Install from the registry
- We connected with no credentials and asked for its tool list: it listed 17 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)
- 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.
