FastApply

FastApply MCP Server provides intelligent code editing capabilities through integration with local language models, enabling precise code modifications using AST-grep for structural analysis and ripgrep for fast text search. Built by betmoar, it combines multiple search and analysis engines including ast-grep for pattern matching, ripgrep for text search, and custom AST analysis tools to provide comprehensive code understanding and safe refactoring operations with automatic backup creation, validation, and rollback capabilities. The implementation supports batch operations, symbol analysis, reference tracking, and security-focused path validation, making it valuable for large-scale codebase refactoring, automated code quality improvements, and development workflows where precise structural code changes are needed across multiple files while maintaining code integrity and safety.
