// key findings
🚨
Secret credentials may flow to a network call
2 flows detected: OPENAI_API_KEY. We can’t prove the destination matches the brand the credential belongs to.
🚨
Code appears obfuscated
2 files are unreadable to a human reviewer. Cannot audit what they do.
🔐
You'll be asked for 5 credentials: MEMOS_EMBEDDING_API_KEY, MEMOS_KEY, GOOGLE_API_KEY, ANTHROPIC_API_KEY, HF_TOKEN
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

17/17 tools missing one or more hints — memos_store (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); memos_search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); memos_retrieve (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +14 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.

Readable source code

2 files are minified or bundled, which is usually build output rather than concealment

Ship unminified, readable source.

Secrets not logged

85 secret values sent to log/error

Redact or omit secret values from log output.

Domain consistency

npm scope @mem-os doesn't match GitHub owner markgatcha

Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.

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.
