What we tested and what we didn't

Tested on 2026-11-03

  • Install from the registry
  • We connected with no credentials and asked for its tool list: it listed 6 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)
  • 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.

Known security issues

Not checked (remote-only): hosted endpoint, version unknown.
