About
The Browser Agent Protocol (BAP) offers a standardized, AI-optimized method for agents to control web browsers. It employs JSON-RPC 2.0 over WebSocket for robust communication and leverages semantic selectors, like accessibility roles and text content, instead of brittle CSS selectors, making interactions more reliable and comprehensible for AI. BAP is built with an accessibility-first approach, provides token-efficient observations for LLMs, and integrates seamlessly with the Model Context Protocol (MCP). It supports composite actions, stable element references, screenshot annotations for vision models, multi-context browser sessions, and optional human-in-the-loop approval workflows, ensuring powerful and controlled browser automation for AI agents.
