// key findings
🚨
Known vulnerabilities in dependencies: 1 critical, 2 high
Affects packages this MCP installs at runtime. Upgrade or remove the affected dependency.
⚠️
Tests do not pass
Either the test suite is broken or the code regressed. Either way the published behaviour can’t be verified by the publisher’s own tests.
🔐
You'll be asked for 3 credentials: COSMOS_MCP_KEY, COSMOS_SYSTEM_KEY, COSMOS_TOKEN
These are read from process.env at runtime. Make sure you trust where they’ll be sent.
// known CVEs in dependencies1 critical2 high

Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

// required environment variables
This server reads these from process.env. You'll be asked to provide them before it can run.
configCOSMOS_BASE_URL
configCOSMOS_IMESSAGE_DB
configCOSMOS_MCP_CLIENT_NAME
🔐 secretCOSMOS_MCP_KEY— (from token file) pmk_... per-user key. Honored for back-compat.
🔐 secretCOSMOS_SYSTEM_KEY— (unset) Single-tenant mode. Sends X-System-Key instead of X-MCP-Key. Requires COSMOS_USER_ID. For internal testing before per-user keys are deployed.
🔐 secretCOSMOS_TOKEN— CI. Set =pmk_… in env. It takes precedence over the keychain, so existing pipelines keep working untouched.
configCOSMOS_URL
configCOSMOS_USER_ID— (from token file) Polarity user id.
