Rust MCP Filesystem

Rust MCP Filesystem

What is Rust MCP Filesystem about?

Rust MCP Filesystem provides a high‑performance, asynchronous MCP server dedicated to filesystem management. It offers a secure, read‑only‑by‑default environment with optional write access, enabling precise file querying and manipulation through glob patterns and nested directory creation.

How to use Rust MCP Filesystem?

1. Installation – Follow the step‑by‑step guide in the project documentation to build the binary with cargo build --release or download a pre‑compiled release.
2. Configuration – Adjust the server’s configuration file (e.g., config.toml) to set the root directory, enable write permissions, and define any custom glob rules.
3. Running – Start the server with ./target/release/rust-mcp-filesystem --config config.toml. The server will listen for MCP requests on the configured port.
4. Interaction – Use any MCP‑compatible client to send filesystem commands such as list, read, write, or glob to the server’s endpoint.

Key features of Rust MCP Filesystem

• High performance: Rust + async I/O ensures low latency and high throughput.
• Read‑only default: Prevents accidental writes; write access must be explicitly enabled.
• Advanced glob search: Full glob syntax (*.rs, src/**/*.txt, logs/error-???.log, etc.) for precise file filtering.
• Nested directory creation: Supports creating deep directory structures in a single call.
• Lightweight binary: No external runtimes; a single compiled executable.
• Seamless integration: Works with rust-mcp-sdk and rust-mcp-schema for type‑safe MCP communication.

Use cases of Rust MCP Filesystem

• File exploration tools – Power IDE extensions or CLI utilities that need rapid file discovery.
• Automation pipelines – Invoke filesystem operations from CI/CD workflows without spawning heavy runtimes.
• System integration – Provide a secure, read‑only view of a filesystem to remote services via MCP.
• Sandboxed environments – Offer limited write capabilities for controlled application testing.

FAQ from the Rust MCP Filesystem

• Q: Do I need Node.js or Python to run this server?
  A: No. The server is a self‑contained Rust binary.
• Q: How can I enable write access?
  A: Set allow_write = true in the configuration file and restart the server.
• Q: Is there support for Windows paths?
  A: Yes, the server uses Rust’s cross‑platform std::fs APIs.
• Q: Where can I find the full list of capabilities?
  A: See the "Capabilities" section of the online documentation.
• Q: How do I contribute?
  A: Fork the repository, make changes, and open a pull request following the contribution guidelines in CONTRIBUTING.md.

Rust MCP Filesystem

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.

🚀 Refer to the project documentation for installation and configuration instructions.

Features

• ⚡ High Performance: Built in Rust for speed and efficiency, leveraging asynchronous I/O to handle filesystem operations seamlessly.
• 🔒 Read-Only by Default: Starts with no write access, ensuring safety until explicitly configured otherwise.
• 🔍 Advanced Glob Search: Supports full glob pattern matching allowing precise filtering of files and directories using standard glob syntax.For example, patterns like *.rs, src/**/*.txt, and logs/error-???.log are valid and can be used to match specific file types, recursive directory searches, or patterned filenames.
• 📁 Nested Directories: Improved directory creation, allowing the creation of nested directories.
• 📦 Lightweight: Standalone with no external dependencies (e.g., no Node.js, Python etc required), compiled to a single binary with a minimal resource footprint, ideal for both lightweight and extensive deployment scenarios.
