Mcp Server Filesystem

MCP Filesystem Server

> DISCLAIMER: This is an unofficial port of Claude's filesystem MCP server implementation, created solely as a Proof of Concept (POC). This project is not affiliated with Anthropic and should not be used in production environments. It was created to demonstrate and explore MCP server functionality. > > The original implementation and concept were demonstrated by Claude (Anthropic) during interactive sessions. This port serves educational purposes only.

Quick Start

1. Install using UVX:

uv venv
.venv\Scripts\activate  # On Windows
uv pip install -e .

Usage with Claude Desktop

1. Edit your claude_desktop_config.json:

{
  "mcpServers": {
    "myFiles": {
      "command": "mcp-server-filesystem",
      "args": [
        "D:/"  // Replace with your desired directory
      ]
    }
  }
}

You can add multiple directories:

{
  "mcpServers": {
    "myFiles": {
      "command": "mcp-server-filesystem",
      "args": [
        "D:/",
        "C:/Users/YourUsername/Documents",
        "~/Desktop"
      ]
    }
  }
}

1. Restart Claude Desktop to apply changes

1. In Claude Desktop:

• Click the paperclip icon
• Select the MCP menu (two electrical plugs connecting)
• Your filesystem server will be available in the integrations

Security Note

Only directories specified in the args array will be accessible. The server enforces strict path validation to prevent access outside allowed directories.

Troubleshooting

1. Command not found:

• Make sure the package is installed (uv pip list)
• Check your Python environment is activated

1. Access denied:

• Verify the directories in args exist
• Ensure you have read permissions for specified directories

1. Server not showing in Claude Desktop:

• Check your config file syntax
• Restart Claude Desktop after config changes
