Know if an MCP server is safe before you install it
Scan any MCP server for leaked secrets, missing auth, and quality issues. Get a letter grade across security, reliability, documentation, and LLM compatibility.
Most MCP servers ship without a single quality check
The ecosystem has thousands of public servers, but no standard way to evaluate safety or quality. The data paints a grim picture.
5.2%
of public repos leak secrets in committed code
~2,000
public servers have zero authentication

From URL to quality report in three steps
Point at a server
Paste a GitHub URL, npm package name, or live endpoint. Lint fetches the source and dependencies automatically.
Get your report
Lint scans for secrets, CVEs, auth gaps, and documentation quality. Results include a letter grade (A through F) with detailed findings.
Ship with confidence
Embed a quality badge in your README. Set up the GitHub Action for continuous scanning on every push.
Comprehensive scanning, zero configuration
Lint checks what matters: secrets, vulnerabilities, auth, docs, and LLM compatibility.
Secret detection
40+ patterns with entropy analysis. Catches API keys, tokens, and credentials that regex alone would miss.
Dependency CVE scanning
Checks every dependency against the OSV.dev vulnerability database. Flags critical and high-severity issues.
4D quality scoring
Scores across security, reliability, documentation, and LLM compatibility. Letter grade from A to F.
Embeddable badges
SVG badges for your README, like build-passing but for MCP quality. Shields.io compatible.
CI/CD integration
GitHub Action and SARIF output for GitHub Code Scanning. Quality gates on every pull request.
Comparative benchmarks
See where your server ranks. Percentile scoring across the entire scanned ecosystem.
