kontext-security · kontext-security/browser-use-mcp-server
An MCP server that allows AI agents to control web browsers using Playwright, enabling web browsing and data extraction directly from clients like Cursor.
Browse the web, directly from Cursor etc.
Preview
What you can do with it
- Automate web research for an AI agent by browsing and extracting information from websites.
- Perform actions on web pages, such as filling forms or clicking buttons, programmatically.
- Scrape data from multiple web sources to feed into an agent's analysis.
Safety check
Usable, but read the notes first.
- ●Installer downloads a remote script and pipes it to the shell.

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

Features
- Browser Automation: Control browsers through AI agents
- Dual Transport: Support for both SSE and stdio protocols
- VNC Streaming: Watch browser automation in real-time
- Async Tasks: Execute browser operations asynchronously
Local Development
To develop and test the package locally:
-
Build a distributable wheel:
# From the project root directory uv build -
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 -
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 -
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)
