About
Regex-mcp is an in-editor server that transforms how developers interact with regular expressions. By integrating directly into popular Model Context Protocol (MCP) clients like Claude Code, Cursor, and VS Code Copilot, it eliminates the need to switch contexts for regex operations. Developers can test patterns against text, receive token-by-token explanations, validate syntax with common pitfall warnings, debug visually, perform find-and-replace, and even generate complex regex from natural language descriptions, all without leaving their development environment.
