Public Browser is an MCP server that lets AI coding assistants like Claude Code and Cursor control Chrome directly via the DevTools Protocol. It reduces token usage and session cost by combining multiple actions into single calls and returns compact, diff based responses. The project includes extensive benchmarks, detailed documentation and offers Python and Node APIs for programmatic use without an LLM.
