Sketchagent

Sketchagent is a browser-based 3D mesh playground for coding agents. You can connect your own agent over MCP or run directly in the browser tab, with no local Blender install or plugin setup required. Built on three.js and manifold-3d, it supports boolean and mesh editing in JavaScript. It is positioned as a browser-based alternative to desktop setups such as blender-mcp. The playground also lets you share a run, so others can open and try the same prompt.
