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
11/11 tools missing one or more hints — execute_query (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_database_schema (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); execute_dml_ddl_dcl_tcl (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +8 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
6/11 tool handlers declare input schemas (55%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool test coverage
Only 0/11 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, 2 high severity in production deps — @modelcontextprotocol/sdk@1.8.0 (high), @modelcontextprotocol/sdk@1.8.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
5 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
