browser-use-mcp-server

Prerequisites

• uv - Fast Python package manager
• Playwright - Browser automation
• mcp-proxy - Required for stdio mode

# Install prerequisites
curl -LsSf https://astral.sh/uv/install.sh | sh
uv tool install mcp-proxy
uv tool update-shell

Environment

Create a .env file:

OPENAI_API_KEY=your-api-key
CHROME_PATH=optional/path/to/chrome
PATIENT=false  # Set to true if API calls should wait for task completion

Installation

# Install dependencies
uv sync
uv pip install playwright
uv run playwright install --with-deps --no-shell chromium

Usage

SSE Mode

# Run directly from source
uv run server --port 8000

stdio Mode

# 1. Build and install globally
uv build
uv tool uninstall browser-use-mcp-server 2>/dev/null || true
uv tool install dist/browser_use_mcp_server-*.whl

# 2. Run with stdio transport
browser-use-mcp-server run server --port 8000 --stdio --proxy-port 9000

Client Configuration

Local Development

To develop and test the package locally:

1. Build a distributable wheel:

   # From the project root directory
   uv build
   

2. Install it as a global tool:

   uv tool uninstall browser-use-mcp-server 2>/dev/null || true
   uv tool install dist/browser_use_mcp_server-*.whl
   

3. Run from any directory:

   # Set your OpenAI API key for the current session
   export OPENAI_API_KEY=your-api-key-here
   
   # Or provide it inline for a one-time run
   OPENAI_API_KEY=your-api-key-here browser-use-mcp-server run server --port 8000 --stdio --proxy-port 9000
   

4. After making changes, rebuild and reinstall:

   uv build
   uv tool uninstall browser-use-mcp-server
   uv tool install dist/browser_use_mcp_server-*.whl
   

Docker

# Run with default VNC password
docker build -t browser-use-mcp-server .
docker run --rm -p8000:8000 -p5900:5900 browser-use-mcp-server
