Hwatu MCP Server
Your agents are blind without hwatu hwatu is a visual verification harness for coding agents, built as a WebKit daemon. Instead of "looks right to me", your agent gets one-call verified page checks in ~35 ms, pixel-diff scores it can climb, animations as numbers, and headless windows that never steal your focus, at any parallelism.
People who need browser automation tools inside Claude, Cursor, VS Code, or another MCP client. The project is written in Rust.
