The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
All four hints declared on every tool
11/11 tools missing one or more hints — geocode (missing: destructiveHint, idempotentHint, openWorldHint); reverse_geocode (missing: destructiveHint, idempotentHint, openWorldHint); straight_line_distance (missing: destructiveHint, idempotentHint, openWorldHint), +8 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool annotations match behaviour
1 read-only tool performs write/delete/exec — poi_details (line 180: OSM_ID.exec(osm_id))
Either remove the readOnlyHint:true annotation, or remove the write/delete call from the tool handler.
Tool inputs are validated
10/11 tool handlers declare input schemas (91%)
Declare an inputSchema with zod/joi/yup on every tool definition.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
