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.
get-workoutsGet workouts between start and end dates. Returns all workouts if no dates are provided. Returns workouts in descending order of date and limits the number of workouts returned. Max 10 workouts. Example: { "limit": 5, // Optional: Number of workouts (1-10, default: 10) …
get-exercise-progress-by-idsGet progress history for specific exercises between start and end dates. Returns exercise data including weights, reps, and sets for each workout. Results are ordered by date descending. Useful for tracking progress over time for particular exercises. Example: { "exerciseIds": ["bench-press-123",…
get-exercisesGet comprehensive exercise data including frequency of use, categorization, and metadata. Results are sorted by usage frequency. Supports filtering by name search and date range. Example: { "searchTerm": "bench press", // Optional: Filter exercises by name "excludeUnused": true, …
get-routinesGet user's saved workout routines. Returns all custom and preset routines with their full exercise details, including sets, reps, and rest periods. Example: {} // No parameters required

HEVY_API_BASE_URLHEVY_API_KEY"": "your-api-key-here"PORTTool annotations
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
4/4 tools missing one or more hints — get-workouts (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get-exercise-progress-by-ids (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get-exercises (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +1 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 0/4 tool handlers declare input schemas (0%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 0/4 tool handlers wrap calls in try/catch (0%)
Wrap each tool handler body in try/catch and return a structured error response.
Tool test coverage
Only 0/4 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 15 high severity in production deps — @modelcontextprotocol/sdk@1.9.0 (high), @modelcontextprotocol/sdk@1.9.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
1 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
