10/10 tools missing one or more hints — add_or_edit_product (missing: destructiveHint, idempotentHint, openWorldHint); autocomplete (missing: destructiveHint, idempotentHint, openWorldHint); call_api (missing: destructiveHint, idempotentHint, openWorldHint), +7 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 0/10 tool handlers declare input schemas (0%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 0/10 tool handlers wrap calls in try/catch (0%)
Wrap each tool handler body in try/catch and return a structured error response.
Production dependencies are patched
0 critical, 2 high severity in production deps — @modelcontextprotocol/sdk@1.24.0 (high), @modelcontextprotocol/sdk@1.24.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
