1/87 tools have annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
87/87 tools missing one or more hints — confirm_action (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); reject_action (missing: idempotentHint, openWorldHint); list_pending_actions (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +84 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
75/87 tool handlers declare input schemas (86%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 0/87 tool handlers wrap calls in try/catch (0%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tests exist
No test files found
Add tests that exercise each declared tool.
Production dependencies are patched
0 critical, 1 high severity in production deps — fast-xml-parser@5.4.2 (high), fast-xml-parser@5.4.2 (low)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
