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.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
whoop_get_recoveryRecovery scores (recovery %, HRV, resting heart rate) over a date range.
whoop_get_sleepSleep activities including stages (REM/deep/light) and sleep performance.
whoop_get_cyclesPhysiological cycles including day strain and average heart rate.
whoop_get_workoutsWorkout activities including strain, energy, and heart-rate zones.
whoop_get_profileBasic WHOOP user profile.

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
5/5 tools missing one or more hints — whoop_get_recovery (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); whoop_get_sleep (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); whoop_get_cycles (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +2 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 inputs are validated
Only 0/5 tool handlers declare input schemas (0%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 0/5 tool handlers wrap calls in try/catch (0%)
Wrap each tool handler body in try/catch and return a structured error response.
Tests exist
No test files found
Add tests that exercise each declared tool.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.0 (high), @modelcontextprotocol/sdk@1.12.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
