Ohm Mcp
Brings AST-powered Python refactoring directly into Claude through MCP tools. You get extract method, dead code elimination, god object detection, SOLID violation analysis, and project-wide symbol renaming. The server wraps Python's ast module to deliver safe, rollback-capable transformations without the usual grep-and-replace chaos. Install via npx or pip, then call tools like analyze_architecture or detect_dead_code from any MCP client. Built for workflows where you want concrete refactoring operations, not just suggestions. Includes type coverage analysis, duplicate detection, and a quality dashboard that surfaces O(n²) patterns and test coverage gaps. The operation history lets you undo changes if a refactoring goes sideways.
