# browser-use MCP server [](https://docs.browser-use.com) [](LICENSE) > **Project Note**: This MCP server implementation builds upon the [browser-use/web-ui](https://github.com/browser-use/web-ui) foundation. Core browser automation logic and configuration patterns are adapted from the original project. AI-driven browser automation server implementing the Model Context Protocol (MCP) for natural language browser control. ## Features - ? **MCP Integration** - Full protocol implementation for AI agent communication - ? **Browser Automation** - Page navigation, form filling, and element interaction - ?️ **Visual Understanding** - Screenshot analysis and vision-based interactions - ? **State Persistence** - Maintain browser sessions between tasks - ? **Multi-LLM Support** - OpenAI, Anthropic, Azure, DeepSeek integration ## Quick Start ### Prerequisites - Python 3.11 or higher - uv (fast Python package installer) - Chrome/Chromium browser ### Installation #### Claude Desktop On MacOS: `~/Library/Application Support/Claude/claude_desktop_config.json` On Windows: `%APPDATA%/Claude/claude_desktop_config.json` ```json "mcpServers": { "browser-use": { "command": "uvx", "args": [ "mcp-server-browser-use", ], "env": { "OPENROUTER_API_KEY": "", "OPENROUTER_ENDPOINT": "https://openrouter.ai/api/v1", "OPENAI_ENDPOINT": "https://api.openai.com/v1", "OPENAI_API_KEY": "", "ANTHROPIC_ENDPOINT": "https://api.anthropic.com", "ANTHROPIC_API_KEY": "", "GOOGLE_API_KEY": "", "AZURE_OPENAI_ENDPOINT": "", "AZURE_OPENAI_API_KEY": "", "DEEPSEEK_ENDPOINT": "https://api.deepseek.com", "DEEPSEEK_API_KEY": "", "MISTRAL_API_KEY": "", "MISTRAL_ENDPOINT": "https://api.mistral.ai/v1", "OLLAMA_ENDPOINT": "http://localhost:11434", "ANONYMIZED_TELEMETRY": "true", "BROWSER_USE_LOGGING_LEVEL": "info", "CHROME_PATH": "", "CHROME_USER_DATA": "", "CHROME_DEBUGGING_PORT": "9222", "CHROME_DEBUGGING_HOST": "localhost", "CHROME_PERSISTENT_SESSION": "false", "BROWSER_HEADLESS": "false", "BROWSER_CHROME_INSTANCE_PATH" : "", "BROWSER_DISABLE_SECURITY": "false", "BROWSER_WINDOW_WIDTH": "1280", "BROWSER_WINDOW_HEIGHT": "720", "BROWSER_TRACE_PATH": "trace.json", "BROWSER_RECORDING_PATH": "recording.mp4", "RESOLUTION": "1920x1080x24", "RESOLUTION_WIDTH": "1920", "RESOLUTION_HEIGHT": "1080", "VNC_PASSWORD": "youvncpassword", "MCP_MODEL_PROVIDER": "anthropic", "MCP_MODEL_NAME": "claude-3-5-sonnet-20241022", "MCP_TEMPERATURE": "0.3", "MCP_MAX_STEPS": "30", "MCP_USE_VISION": "true", "MCP_MAX_ACTIONS_PER_STEP": "5", "MCP_TOOL_CALL_IN_CONTENT": "true" } } ``` ### Local Development ```json "browser-use": { "command": "uv", "args": [ "--directory", "/path/to/mcp-browser-use", "run", "mcp-server-browser-use" ], "env": { ... } } ``` ## Development ```bash # Install dev dependencies uv sync # Run with debugger npx @modelcontextprotocol/inspector uv --directory . run mcp-server-browser-use ``` ## Troubleshooting - **Browser Conflicts**: Close all Chrome instances before starting. - **API Errors**: Verify API keys in environment variables match your LLM provider. - **Vision Support**: Ensure `MCP_USE_VISION=true` for screenshot analysis. ## Provider Configuration The server supports multiple LLM providers through environment variables. Here are the available options for `MCP_MODEL_PROVIDER`: | Provider | Value | Required Env Variables | |----------|--------|----------------------| | Anthropic | `anthropic` | `ANTHROPIC_API_KEY`
`ANTHROPIC_ENDPOINT` (optional) | | OpenAI | `openai` | `OPENAI_API_KEY`
`OPENAI_ENDPOINT` (optional) | | Azure OpenAI | `azure_openai` | `AZURE_OPENAI_API_KEY`
`AZURE_OPENAI_ENDPOINT` | | DeepSeek | `deepseek` | `DEEPSEEK_API_KEY`
`DEEPSEEK_ENDPOINT` (optional) | | Gemini | `gemini` | `GOOGLE_API_KEY` | | Mistral | `mistral` | `MISTRAL_API_KEY`
`MISTRAL_ENDPOINT` (optional) | | Ollama | `ollama` | `OLLAMA_ENDPOINT` (optional, defaults to localhost:11434) | | OpenRouter | `openrouter` | `OPENROUTER_API_KEY`
`OPENROUTER_ENDPOINT` (optional) | ### Notes: - For endpoints marked as optional, default values will be used if not specified - Temperature can be configured using `MCP_TEMPERATURE` (default: 0.3) - Model can be specified using `MCP_MODEL_NAME` - For Ollama models, additional context settings like `num_ctx` and `num_predict` are configurable ## Credits This project extends the [browser-use/web-ui](https://github.com/browser-use/web-ui) under MIT License.
