Installation

1. Create Project Directory

mkdir mcp-screenshot-server
cd mcp-screenshot-server

2. Create the Files

Create each file with the contents from the artifacts above:

• screenshot_server.py - Main server
• config.py - Configuration
• screenshot_utils.py - Utilities
• requirements.txt - Dependencies

3. Install Dependencies

# Using your specific Python environment
/Users/antond/.pyenv/versions/3.12.4/envs/python_3_12/bin/pip install -r requirements.txt

4. Test the Server

cd mcp-screenshot-server
/Users/antond/.pyenv/versions/3.12.4/envs/python_3_12/bin/python screenshot_server.py

You should see: "Starting MCP Screenshot Server..." and "Screenshots will be saved to: /Users/antond/Downloads/MCP_Screenshots"

Configuration

Add to your Claude Desktop config file:

{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-filesystem",
        "/Users/antond/Desktop",
        "/Users/antond/Downloads"
      ]
    },
    "screenshot": {
      "command": "/Users/antond/.pyenv/versions/3.12.4/envs/python_3_12/bin/python",
      "args": ["/full/path/to/mcp-screenshot-server/screenshot_server.py"]
    }
  }
}

Troubleshooting

Permission Issues (macOS)

Grant screen recording permissions:

1. System Preferences → Security & Privacy → Screen Recording
2. Add Claude Desktop to allowed apps
3. Restart Claude Desktop

Import Errors

# Ensure all dependencies are installed
/Users/antond/.pyenv/versions/3.12.4/envs/python_3_12/bin/pip install --upgrade -r requirements.txt

Path Issues

• Use absolute paths in Claude Desktop configuration
• Verify Python executable path with: which python
• Check file permissions in project directory
