# Surgical Change Control MCP Server An [MCP](https://modelcontextprotocol.io) server implementation of the **Surgical Change Control** skill. This server provides tools to enforce disciplined, minimal AI edits by requiring scope validation and factual verification before modifications are applied. ## Tools - `define_change_boundary`: Validates the smallest possible scope for a requested change. - `detect_multi_location_impact`: Scans for similar patterns across files to prevent unapproved bulk edits. - `verify_minimal_blast_radius`: Ensures proposed changes don't touch unrelated working code. - `verify_claim_confidence`: Classifies claims as Verified, Likely, or Unverified to prevent hallucination-driven edits. ## Installation ### For Perplexity Mac App (Desktop) 1.
