browser-use MCP server

Project Note: This MCP server implementation builds upon the 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

  "command": "uv",
  "args": [
    "--directory",
    "/path/to/mcp-browser-use",
    "run",
    "mcp-server-browser-use"

  }
}

Development

# 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
