Tool 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
35/35 tools missing one or more hints — greet (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); calendar_listEvents (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); calendar_createEvent (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +32 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
24/35 tool handlers declare input schemas (69%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
34/35 tool handlers wrap calls in try/catch (97%)
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, 7 high severity in production deps — @modelcontextprotocol/sdk@1.10.2 (high), @modelcontextprotocol/sdk@1.10.2 (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.

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.
