Code Impact Mcp

Before you commit that refactor, this server tells you what breaks. It builds a local dependency graph for TypeScript and JavaScript repos and exposes four stdio tools: gate_check runs a pre-commit safety gate that returns PASS/WARN/BLOCK verdicts based on blast radius and cycle detection, analyze_impact shows you the transitive ripple of changing specific files with a 0-1 risk score, detect_cycles surfaces strongly connected components so you catch circular dependencies before release, and get_dependencies maps import relationships for single files. No database, no cloud API. The install-hook command wires a Husky pre-commit gate if you want to block risky commits automatically. Useful when an AI agent is editing multiple files and you need a bounded go/no-go answer in seconds.
