What it does

MCP Doctor is the missing security and quality toolkit for the MCP ecosystem:

• Security Scan — 8 engines: prompt injection, path traversal, credential leakage, network exfiltration, command injection, SSRF, supply chain, excessive permissions
• Quality Score — 0-100 automated scoring (security 35%, maintenance 25%, docs 15%, testing 15%, community 10%)
• Server Comparison — Side-by-side comparison of two MCP servers
• Curated Registry — 100+ MCP servers with pre-computed scores and 20+ categories
• One-Command Install — scan + score + install in one step
• CI/CD Audit — exit codes for pipeline integration, JSON output

pip install mcp-doctor
mcp-doctor scan @modelcontextprotocol/server-filesystem
mcp-doctor list --category database --sort score
mcp-doctor audit @modelcontextprotocol/server-filesystem --threshold 60

Before installing an MCP server, run it through the Doctor! 🩺
