2. Drag & Drop the file to Claude Desktop
3. Configure working directory when prompted
4. Start using professional tools immediately

Manual Installation

# Clone the repository
git clone https://github.com/sandr/filesystem-mcp.git
cd filesystem-mcp

# Create and activate a virtual environment (recommended)
python -m venv venv
# On Windows: .\venv\Scripts\Activate.ps1
# On Unix/Mac: source venv/bin/activate

# Install with all dependencies
pip install -e .[dev,test]

# Install development dependencies (optional)
pip install -r requirements-dev.txt

Claude Desktop Configuration

After installation, configure Claude Desktop to use the filesystem MCP server by adding the following to your Claude Desktop configuration file (claude_desktop_config.json):

Windows:

{
  "mcpServers": {
    "filesystem-mcp": {
      "command": "python",
      "args": ["-m", "filesystem_mcp"],
      "env": {
        "PYTHONPATH": "D:\\path\\to\\filesystem-mcp\\src",
        "PYTHONUNBUFFERED": "1",
        "FASTMCP_LOG_LEVEL": "INFO"
      },
      "cwd": "D:\\path\\to\\your\\working\\directory"
    }
  }
}

macOS/Linux:

{
  "mcpServers": {
    "filesystem-mcp": {
      "command": "python",
      "args": ["-m", "filesystem_mcp"],
      "env": {
        "PYTHONPATH": "/path/to/filesystem-mcp/src",
        "PYTHONUNBUFFERED": "1",
        "FASTMCP_LOG_LEVEL": "INFO"
      },
      "cwd": "/path/to/your/working/directory"
    }
  }
}

Configuration Notes:

• Replace D:\\path\\to\\filesystem-mcp\\src with the actual path to your cloned repository's src directory
• Set cwd to your preferred working directory for file operations
• The server supports the following optional environment variables:
  • FASTMCP_LOG_LEVEL: Set to DEBUG, INFO, WARNING, or ERROR
  • GIT_USERNAME: Default Git username for commits
  • GIT_EMAIL: Default Git email for commits

Docker Installation

Run the MCP server in a container with all dependencies:

# Build the multi-platform Docker image
docker buildx build -t filesystem-mcp \
  --platform linux/amd64,linux/arm64 .

# Run the container
docker run -d --name filesystem-mcp \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v $(pwd):/workspace \
  filesystem-mcp

🤖 Help System & Status Tools

Multilevel Help System

Get comprehensive guidance for all tools:

# Overview of all categories and tools
get_help()

# Detailed help for file operations
get_help('file_operations')

# Specific tool documentation with examples
get_help('file_operations', 'read_file')

Help Categories:

• file_operations - File reading, writing, directory management
• git_operations - Repository cloning, status, commits, branches
• docker_operations - Container listing, resource monitoring
• system_tools - Help and status functionality

System Status Monitoring

Monitor system resources and server health:

# Comprehensive system status
get_system_status()

# Resource monitoring only
get_system_status(include_processes=True, include_disk=True)

# Network and system info
get_system_status(include_network=True)

Status Metrics:

• CPU usage (physical/logical cores, frequency, load)
• Memory statistics (total, available, usage percentage)
• Disk usage (total, used, free space)
• Process information (top CPU consumers)
• Network interfaces (IP addresses, status)
• Server health (FastMCP version, tool count, status)

🛠️ Usage

Starting the Server

# Start the MCP server (default: http://0.0.0.0:8000)
python -m filesystem_mcp

# With custom host and port
python -m filesystem_mcp --host 127.0.0.1 --port 8080
