@refactogent/mcp-serverEverything you need for safe, intelligent refactoring
Automatically extract interfaces and types to separate .types.ts files with smart import management.
Git-based safety points with automatic rollback if validation fails. Never break your code.
Understand the blast radius of changes with dependency tracing and risk scoring.
Run tests, linting, and type checking automatically after refactoring changes.
AST-based parsing with complexity metrics, dependency mapping, and symbol indexing.
TypeScript, JavaScript, Python, and Go support with language-specific optimizations.
Simple workflow, powerful results
Install globally and run on your codebase
AST parsing finds refactoring opportunities
Types extracted, imports updated automatically
Run your build and tests - everything works
