Filesystem MCP

A Model Context Protocol server that allows AI assistants to safely search, read, edit, and manage local files within user-specified directories. It provides 14 tools for file operations, including grep-like search with RE2 regex, exact-match text editing, and patching, while enforcing security by blocking sensitive files and requiring confirmation for risky changes like deleting non-empty folders.
