// key findings
🚨
Secret credentials may flow to a network call
1 flow detected: CRON_SECRET. We can’t prove the destination matches the brand the credential belongs to.
🚨
Known vulnerabilities in dependencies: 2 critical, 18 high
Affects packages this MCP installs at runtime. Upgrade or remove the affected dependency.
🔐
You'll be asked for 4 credentials: CRON_SECRET, GOOGLE_CLIENT_SECRET, OPENAI_API_KEY, TURSO_AUTH_TOKEN
These are read from process.env at runtime. Make sure you trust where they’ll be sent.

These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

search

Semantic search over your Google Drive documents. Returns relevant text chunks with source information.

list_documents

List all indexed Google Drive documents with metadata (title, last modified, etc).

expand_document

Get the full text content of a document by its ID. Use this after searching to get complete document context.

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

3/3 tools missing one or more hints — search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_documents (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); expand_document (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint). 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.).

Tests exist

No test files found

Add tests that exercise each declared tool.

Secrets stay with their owner

1 secret sent to a request target we could not resolve (CRON_SECRET → 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.

Production dependencies are patched

2 critical, 18 high severity in production deps — better-auth@1.4.12 (critical), next@16.1.2 (critical)

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

// 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.
