Purpose
This tool acts as a Model Context Protocol (MCP) server that allows AI agents and coding assistants (like Cursor or Claude) to autonomously browse and interact with the web using Playwright.

Security Assessment
Risk: Medium. This server requires an OpenAI API key to function, which must be injected via the environment. As a browser automation tool, its core purpose is to make outbound network requests, navigate the internet, and extract data. The automated light code scan found no hardcoded secrets or malicious scripts within the project files, and it does not explicitly request dangerous system permissions. However, the inherent nature of AI-driven web browsing means it processes and transmits potentially sensitive data, and its actions depend heavily on the instructions given by the controlling AI agent.

Quality Assessment
The project is licensed under the permissive MIT license and features a clear, well-documented README. It enjoys a solid level of community trust with over 800 GitHub stars. The automated health check confirms it is an active repository, although the last push was 278 days ago, meaning it may not have the most recent dependency updates. The codebase is lightweight, consisting of only 12 scanned files with no detected dangerous patterns.

Verdict
Use with caution — the code itself appears safe and clean, but granting an AI agent autonomous web browsing capabilities carries inherent risks that require proper oversight and secure handling of your API keys.
SUMMARY

Prerequisites

# 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

  • Async Tasks: Execute browser operations asynchronously

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

Using Docker provides a consistent and isolated environment for running the server.

# Build the Docker image
docker build -t browser-use-mcp-server .

# Run the container with the default VNC password ("browser-use")
# --rm ensures the container is automatically removed when it stops
# -p 8000:8000 maps the server port
# -p 5900:5900 maps the VNC port
docker run --rm -p8000:8000 -p5900:5900 browser-use-mcp-server

# Run with a custom VNC password read from a file
# Create a file (e.g., vnc_password.txt) containing only your desired password
echo "your-secure-password" > vnc_password.txt
# Mount the password file as a secret inside the container
docker run --rm -p8000:8000 -p5900:5900 \
  -v $(pwd)/vnc_password.txt:/run/secrets/vnc_password:ro \
  browser-use-mcp-server

Note: The :ro flag in the volume mount (-v) makes the password file read-only inside the container for added security.

VNC Viewer

# Browser-based viewer
git clone https://github.com/novnc/noVNC
cd noVNC
./utils/novnc_proxy --vnc localhost:5900

Default password: browser-use (unless overridden using the custom password method)
