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
255/255 tools missing one or more hints — search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); retrieve (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); ghl_get_all_associations (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +252 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 test coverage
Only 23/255 tools referenced in tests (9%)
Write tests that reference each tool by name so every tool has at least one test.
Secrets not logged
3 secret values sent to console.log
Redact or omit secret values from log output.
Production dependencies are patched
0 critical, 15 high severity in production deps — @modelcontextprotocol/sdk@1.12.1 (high), @modelcontextprotocol/sdk@1.12.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Domain consistency
npm scope @mastanley13 doesn't match GitHub owner keshigami
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.
