Best picks to start with

OK to use in games you sell · most popular first

Blender MCP

The most starred MCP tool on our list (over 31,000). Claude can build and arrange scenes in Blender for you. MIT licensed and actively maintained.

Genesis

World generation

A physics simulation platform aimed more at robotics and generative worlds than typical game dev. Apache-2.0 and very active. Worth a look if you need serious simulation.

Open-Sora

Open video generation under Apache-2.0. Useful for trailer drafts or cutscene previz if you have the GPU for it.

Unity ML-Agents

NPCs & behavior

Unity's own toolkit for training game agents with reinforcement learning. Apache 2.0, mature and still updated.

Unity MCP (Coplay)

The most popular way to let Claude Code or Cursor drive the Unity Editor, with over 15,000 GitHub stars and recent updates. Free and MIT licensed, so it's an easy first install for Unity devs.

TRELLIS

Microsoft's open image-to-3D model with an MIT code license. A strong free pick for asset prototyping.
