// key findings
✅
No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
✅
Open source with a license and README
Anyone can audit the code, the license is declared, and the publisher documents what it does.
// 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.
configCOSMOS_AUTHORIZATIONAdd -e ="Bearer paste_your_token_here" to enable the write tools, or run npx cosmos-mcp login later (see [Authentication](#authentication)).
configCOSMOS_COOKIEunset A full session-bearing Cookie header, if you have one. The AWSALB cookies alone are not enough.
configPROBE_DELAY
configPROBE_GROUPS
configPROBE_OUT
configPROBE_USER_FIELDS

Tool annotations

18/36 tools have annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

19/36 tools missing one or more hints — cosmos_search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cosmos_search_clusters (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cosmos_search_users (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +16 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.

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