What is the Hwatu MCP Server?

Verification browser for coding agents: headless WebKit, DOM eval, screenshots, pixel-diff.

What you get

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.

Headless / background / focused as a per-window property, switchable live
Human hand-off: hwatu focus drops the live session into your tiling WM
Pixel-diff scoring: match percent + diff regions + heatmap (diff)
Animations as numbers: duration, easing, velocity (motion)
Deterministic animation frames: pin all animations at time t (seek)
Page state as JSON, tokens not pixels (snapshot)
