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
55/55 tools missing one or more hints — health_check (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cache_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cache_clear (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +52 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
52/55 tool handlers declare input schemas (95%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
33/55 tool handlers wrap calls in try/catch (60%)
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.
