67js is a WebGL2 engine for coding agents that need to build a 3D scene, review it as images, and export stills or MP4. CodePawl, a studio in Vietnam that builds worlds and films with agents, released it for people running Claude Code, Codex, Cursor, Gemini CLI, or OpenCode who want the agent to author the shot, not only the surrounding code. The release includes 23 MCP tools to create and edit scenes, inspect meshes, compare labeled views and normals, and render PNG or video. Each part is a geometry, a matrix, and a material. The agent can glaze a real-time frame or cook a path-traced still, with addons for terrain, vegetation, characters, liquid, and vehicles. The MCP server takes scene recipes and returns images. It does not run arbitrary JavaScript from the agent. Code written for three.js does not run unchanged, and the engine has no mouse editor. CodePawl already renders films and stills from viz3d, its skill for turning a subject into a 3D film or app, in 67js. On the project site, a lit-box scene is 50.9 KB gzip in 67js and 133.8 KB gzip in three.js. npm release 0.16.0 is published as @codepawlhq/67js under the MIT license. It needs Node.js 20.19 or later and a local Chrome or Chromium, and it can render on GPU or CPU. An Xuan announced the release on November 8, 2026. Docs and a live showcase of PBR, cloth, fog, physics, GLB import, and path tracing are at 67js.codepawl.com.
