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

8/8 tools missing one or more hints — browse_drive (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_drive (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_online_peers (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +5 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

5/8 tools referenced in tests (63%)

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

Shell command execution

6 calls in production code run through a shell (bootstrap/diagnostics.js:109, bootstrap/diagnostics.js:117, src/core/dropboxAuth.js:151)

Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.

Production dependencies are patched

0 critical, 2 high severity in production deps — xlsx@0.20.3 (high), xlsx@0.20.3 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

Dependency freshness

3/15 production deps abandoned (no release in 2+ years): pdf-lib@2022-05-12 (4.3y), cfb@2022-06-13 (4.2y), word-extractor@2022-06-29 (4.1y)

// 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 6 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
