// key findings
🚨
Secret credentials may flow to a network call
1 flow detected: HIBP_API_KEY. We can’t prove the destination matches the brand the credential belongs to.
🔐
You'll be asked for 1 credential: HIBP_API_KEY
These are read from process.env at runtime. Make sure you trust where they’ll be sent.
// environment variables
To run this server yourself, you supply these values. They go in your own MCP client configuration and stay on your machine. The secret label means the value is sensitive, not that the server mishandles it.

Tool annotations

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

170/170 tools missing one or more hints — index_codebase (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); analyze_function (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); analyze_code (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +167 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 43/170 tools referenced in tests (25%)

Write tests that reference each tool by name so every tool has at least one test.

Secrets stay with their owner

1 secret sent to a request target we could not resolve (HIBP_API_KEY → dynamic) — often a configured endpoint, not necessarily third-party

Audit where credentials are sent. A NOTION_TOKEN should only reach api.notion.com — never a third-party host.

Claim the listing to review these findings one by one and send us a correction where you disagree, straight to the team. Claiming also means we tell you when the grade moves, and reach you first if we find anything urgent.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 5 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
