Rust MCP Filesystem

What does “Rust MCP Filesystem” MCP Server do?

Rust MCP Filesystem is a blazingly fast, asynchronous, and lightweight MCP (Model Context Protocol) server specifically designed for efficient filesystem operations. Written entirely in Rust, it serves as a high-performance alternative to JavaScript-based MCP servers, enabling seamless integration of filesystem capabilities into AI-assisted development workflows. The server is read-only by default for safety, but can be configured for write access, making it suitable for various secure environments. Its advanced glob search supports complex pattern matching, allowing precise file and directory filtering. Developers can leverage Rust MCP Filesystem to enable AI agents to perform tasks such as directory exploration, glob-based file searching, and nested directory creation, all while maintaining minimal resource usage and high reliability.

No explicit list of MCP resources is provided in the available documentation or code.

List of Tools

No direct listing of tools was found in the repository’s main documentation or manifest files. Details about specific tools (such as query_filesystem, read_file, write_file, etc.) are not available in the provided content.

Use Cases of this MCP Server

• Codebase Exploration: Allow AI agents or developers to traverse large codebases quickly using high-performance, asynchronous file listing and glob search.
• Automated File Management: Perform batch file operations, such as searching or categorizing files using glob patterns, without manual intervention.
• Configuration Auditing: Safely scan and audit configuration or log files in a system, leveraging the server’s read-only mode to prevent accidental modifications.
• Data Pipeline Integration: Integrate filesystem interactions into automated data pipelines or CI/CD workflows, enabling programmatic directory creation and file access.
• Deployment in Resource-Constrained Environments: Use the lightweight, dependency-free Rust binary in containers or minimal servers for secure, efficient filesystem operations.

How to set it up

Windsurf

1. Ensure you have the latest Windsurf environment set up.
2. Locate your Windsurf configuration file (e.g., windsurf.json).
3. Add the Rust MCP Filesystem server using the following JSON snippet:

   {
     "mcpServers": {
       "rust-mcp-filesystem": {
         "command": "rust-mcp-filesystem",
         "args": []
       }
     }
   }
   

4. Save the configuration and restart Windsurf.
5. Verify setup by checking the MCP server status in the Windsurf dashboard.

Claude

1. Confirm Claude supports external MCP servers.
2. Locate the configuration section for MCP servers.
3. Add the Rust MCP Filesystem server as follows:

   {
     "mcpServers": {
       "rust-mcp-filesystem": {
         "command": "rust-mcp-filesystem",
         "args": []
       }
     }
   }
   

4. Save changes and restart Claude.
5. Confirm the server appears in available tool integrations.

Cursor

1. Make sure you have Cursor installed with MCP support.
2. Open the Cursor configuration file.
3. Insert the following under the mcpServers section:

   {
     "mcpServers": {
       "rust-mcp-filesystem": {
         "command": "rust-mcp-filesystem",
         "args": []
       }
     }
   }
   

4. Save and reload Cursor.
5. Check that the Rust MCP Filesystem server is running in the toolchain.

Cline

1. Install or update Cline to the latest version supporting MCP.
2. Locate your Cline configuration.
3. Add this JSON to your MCP server config:

   {
     "mcpServers": {
       "rust-mcp-filesystem": {
         "command": "rust-mcp-filesystem",
         "args": []
       }
     }
   }
   

4. Save and restart Cline.
5. Ensure the server is active by running a test file command.

Securing API Keys

To secure API keys or secrets, always use environment variables instead of hard-coding values. Example:

{
  "mcpServers": {
    "rust-mcp-filesystem": {
      "command": "rust-mcp-filesystem",
      "args": [],
      "env": {
        "FS_ROOT_PATH": "/your/safe/path"
      },
      "inputs": {
        "access_mode": "read-only"
      }
    }
  }
}

How to use this MCP inside flows

Using MCP in FlowHunt

To integrate MCP servers into your FlowHunt workflow, start by adding the MCP component to your flow and connecting it to your AI agent:

Click on the MCP component to open the configuration panel. In the system MCP configuration section, insert your MCP server details using this JSON format:

{
  "rust-mcp-filesystem": {
    "transport": "streamable_http",
    "url": "https://yourmcpserver.example/pathtothemcp/url"
  }
}

Once configured, the AI agent is now able to use this MCP as a tool with access to all its functions and capabilities. Remember to change “rust-mcp-filesystem” to whatever the actual name of your MCP server is and replace the URL with your own MCP server URL.

Overview

Our opinion

Based on the available documentation, Rust MCP Filesystem distinguishes itself as a robust and efficient MCP server for filesystem operations, but lacks detailed documentation regarding prompt templates, explicit resources, and tool definitions. Its configuration and setup are straightforward, and it is well-suited for secure and high-performance deployments. However, the absence of detailed MCP resource/tool information limits its immediate out-of-the-box usability for some advanced scenarios.

MCP Score

Score: 5/10 — The server is mature, easy to set up, and has clear performance benefits, but the lack of explicit prompts, resources, and tool documentation reduces its completeness as an MCP server implementation.
