The MCP File System Server is a protocol-compliant server that allows AI assistants to interact with local file systems securely. It supports operations such as listing directory contents, reading files, saving new files, appending content, deleting files, and editing files with pattern matching. The server enforces path validation to prevent security vulnerabilities and restricts access strictly within the specified project directory. This enables seamless integration of AI assistants in development workflows, allowing them to analyze, modify, generate, and organize code and project files efficiently. Its features facilitate debugging, code review, file management, and automation, making it a powerful tool for developers leveraging AI for code and project management.
