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
10/10 tools missing one or more hints — withings_get_weight (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); withings_get_body_composition (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); withings_get_measurements (missing: readOnlyHint, 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.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tool test coverage
Only 0/10 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
No access to sensitive paths
Reads sensitive paths: .env, .env, .env
Remove reads of sensitive system paths. If you genuinely need them, document why in the README.
Secrets not written to files
4 secret values written to files
Avoid persisting secrets to disk. Keep them in memory or your secret manager.
Secrets not logged
6 secret values sent to console.log
Redact or omit secret values from log output.
Production dependencies are patched
0 critical, 14 high severity in production deps — @modelcontextprotocol/sdk@1.18.0 (high), @modelcontextprotocol/sdk@1.18.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
