What is Browser Use MCP?
Browser Use MCP is a browser automation system that enables AI agents to control web browsers through the Model Context Protocol (MCP). It is designed to work with local AI models running via Ollama, allowing secure and efficient browser interactions using locally-hosted LLMs.
How to use Browser Use MCP?
Clone the repository, install dependencies with uv pip install -e . and run playwright install. Ensure Ollama is installed, running (ollama serve), and has a model pulled (e.g., ollama pull qwen3). Use the server via Claude Desktop by configuring the claude_desktop_config.json to point to src/server.py, or run the client directly with python src/client.py src/server.py [task].

- Screenshot capabilities for visual feedback and debugging
- Session management with automatic cleanup
- Interactive mode with continuous feedback loop between AI and browser state
Use cases of Browser Use MCP
- Perform web searches and summarize results using natural language

FAQ from Browser Use MCP
What is the default Ollama model used?
The default model is qwen3. You can change it by setting the OLLAMA_MODEL environment variable or passing the --model flag to the client.
What browsers does it support?
It supports Chrome, Firefox, and Safari through Playwright automation.
How does the system handle errors and cleanup?
Browser sessions are automatically cleaned up, and the system includes graceful recovery from parsing errors, with comprehensive logging for debugging.
What is the architecture of Browser Use MCP?
It uses a client‑server architecture with stdio‑based MCP transport: the user interacts with a client, which communicates via MCP with the server, which in turn controls the browser via Playwright.
Can I use a model other than the default?
Yes, any Ollama‑compatible model can be used. The system is optimized for coding models like qwen3 and qwen2.5-coder:7b, and model selection is configurable via environment variables or command‑line arguments.
