What it does
three.ws Blender is an MCP server, published on npm as @three-ws/blender-mcp, that drives a locally installed Blender 3.0 or newer without its interface. Each tool call starts Blender in background mode, so there is no add-on to install and it can run on a server, in CI or in a container. Tools describe a 3D file's objects, triangles, materials and animation, convert between formats such as GLB, FBX, OBJ, STL and USD, reduce triangle and texture budgets, render preview images that come back inline, and run a bpy script against a scene. Another tool generates a model from a prompt or image on the three.ws Forge service and imports it. It runs on Node.js 20 over stdio.
