概要

What is B4n1web?

B4n1web is an ultra-lightweight agentic browser engine that provides headless browser automation via an MCP (Model Context Protocol) server. It ships as an 11MB binary or SDKs for Python, JavaScript, C#, and Java, and offers 33 MCP tools for navigation, content extraction, network interception, state management, device emulation, file handling, and performance measurement. It is designed for developers and AI agents needing a minimal, cross-platform browser automation layer.

How to use B4n1web?

Install the standalone binary or SDK (e.g., pip install b4n1-web). For MCP usage, run b4n1web mcp in a terminal, then connect via any MCP client (stdio mode, no port needed). Alternatively, use the SDK directly (e.g., from b4n1web import AgentBrowser) to script browser actions in code.
