What it does

Unbrowser is a native, lightweight browser MCP (Model Context Protocol) server designed specifically for LLM agents. It provides browser automation capabilities without the overhead of Chrome, allowing AI agents to interact with web pages efficiently. The tool returns low-token BlockMaps, making it optimized for token usage in LLM contexts.

Key features

• JavaScript execution on web pages
• Link following and navigation
• Form filling and submission
• Cookie management
• Low-token BlockMap output format
• Native binary - no Chrome dependency
• Cross-platform support (macOS, Windows, Linux)
• Rust-based implementation for performance

How to set up

Installation is straightforward as a native binary. Download the latest release from the GitHub repository for your platform, add it to your system PATH or reference it directly in your MCP configuration. Configure your AI agent or LLM application to connect to the unbrowser MCP server by specifying the server endpoint. See the repository documentation for detailed integration examples with Claude and other LLM frameworks.
