// 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.
// known CVEs in dependencies1 low

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

// 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.
configALLOW_WRITESEXPLAIN as a first-class tool - text or JSON format, with optional ANALYZE. ANALYZE for non-SELECT statements requires =1 and always rolls back, so the plan is real but the write doesn't persist.
configGITHUB_OUTPUT
configPOSTGRES_CONNECTION_TIMEOUT_MS10000 TCP connect timeout. Without this, a dead host hangs until the OS gives up (~2 minutes).
configPOSTGRES_MAX_ROWSResult truncation - large result sets are capped at (default 1000) with a truncated: true flag, so a stray SELECT FROM events doesn't blow out the model context.
configPOSTGRES_POOL_MAX5 Max pool connections. Set to 1 for single-threaded backends (pglite-socket, PgBouncer transaction mode).
configPOSTGRES_SSL_REJECT_UNAUTHORIZEDunset Set to false to skip TLS cert verification (for managed DBs using private-CA certs). Connection is still encrypted.
configPOSTGRES_STATEMENT_TIMEOUT_MS30000 Per-statement timeout.
configYAW_HOMEBREW_DIR
configYAW_SCOOP_DIR
Deployment configuration, supplied by whoever hosts the server. Users are not asked for these.

// 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 1 concrete improvement we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
