Culprit MCP Server

Root-cause analysis for agent-driven development. Your coding agent finds what introduced a bug, and verifies its own fix is complete before it commits. It runs locally over stdio via the published package.

People connecting developer tools tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

      "args": [
        "culprit"
      ]
    }
