Test results
Safe mode: only tools labeled read-only were run. How the test works
- !Ready for the newest MCP versionnote
1 warning
- !Uses an older MCP version (2025-11-25). It works today, but it isn't on the July 2026 version (2026-07-28) yet.

1 tip (not scored)
- !The tool list is about 61 KB (roughly 15k tokens). AI apps send it with every message, so it takes that much of the AI's memory before any work starts.
