What the publisher says

From the Secret Hygiene repository's README, as published. We do not edit it. Read it on GitHub

secret-hygiene-mcp

Secret Hygiene scans bounded local files for common secret-like patterns and returns category counts only. It is designed as a pre-commit review signal, not a credential detector with perfect coverage.

Quick start

npm install
npm test
npm start

Use scansecrethygiene inside SECRETHYGIENEROOT.

Privacy and limits

Values, keys, matches, filenames, paths, and source text are never returned. Pattern matching is conservative and can produce false positives or miss unusual formats. Rotate exposed credentials separately.

Nothing above is checked by us. What we check is on the safety report.

Install directly

Runs npx -y secret-hygiene-mcp on your machine. Read the scan report first; the gateway never runs local packages.
