This is insanely cool. Set this up in Grok Build! Unity shipped a free terminal Unity CLI for coding agents, CI, and custom tooling. MCP stays supported, the CLI includes MCP Mode for existing MCP agents, and Unity says both the CLI and MCP are free with no concurrency limits on the MCP server. Dan got Grok 4.5 via Grok Build to install the CLI, build a 3D scene, and export a video. "Same session shipped a playable macOS Island Explorer with Poly Haven CC0 trees, rocks, and cliffs, Crest FFT ocean with shoreline foam, irregular hills, grounded props, FPS walk, and a half-size performance pass when the scene got heavy." -- Daniel Farinax
