The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

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
149/149 tools missing one or more hints — list_databases (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_tables (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_database_summary (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +146 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.
Tests exist
No test files found
Add tests that exercise each declared tool.
Shell command execution
1 child_process call — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
2 critical, 4 high severity in production deps — mysql2@3.6.1 (critical), mysql2@3.6.1 (critical)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dependency freshness
1/12 production deps stale: ajv-formats@2024-03-30 (2.4y)
Domain consistency
npm scope @berthojoris doesn't match GitHub owner moki74
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.
