Rust MCP Filesystem is a blazingly fast, asynchronous, and lightweight MCP (Model Context Protocol) server designed for efficient handling of various filesystem operations. This project is a pure Rust rewrite of the JavaScript-based @modelcontextprotocol/server-filesystem, offering enhanced capabilities, improved performance, and a robust feature set tailored for modern filesystem interactions. It emphasizes high performance through asynchronous I/O and a minimal runtime footprint, while adopting a security posture with Read-Only by Default mode until explicit configuration enables write access. The server includes advanced glob search capabilities, enabling full glob pattern matching to filter files and directories (e.g., *.rs, src/**/*.txt, logs/error-???.log). It also supports MCP Roots to dynamically modify the list of allowed directories (disabled by default) and ZIP archive operations to create or extract archives. It is standalone with no external dependencies and is compiled into a single binary. Built with the rust-mcp-sdk and rust-mcp-schema, it offers a solid foundation for file exploration, automation, and system integration and is distributed via documentation, Docker Hub, and release binaries. MIT-licensed and inspired by the original @modelcontextprotocol/server-filesystem.
