Surgical Change Control MCP Server

An MCP 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.
