MCP for Unity
MCP for Unity is an open-source bridge that lets AI assistants such as Claude Code, Cursor, VS Code, Windsurf, Cline and Gemini CLI manage assets, control scenes, edit scripts and automate tasks in the Unity Editor. It is a Unity package (git URL or OpenUPM) plus a Python MCP server, and its README says it is sponsored and maintained by Aura.
Pricing: Free and open source (MIT).
Latest release 10.3.0:
- chore: sync main (v10.2.0) into beta
- perf(discovery): drop the redundant assembly walk from tool discovery too
- chore: update Unity package to beta version 10.2.1-beta.2
- fix: Claude Code registrations invisible to CheckStatus (duplicate path-variant keys, git worktrees)
Unity CLI MCP server
The Unity CLI includes an MCP server, started with `unity mcp` and built on the Unity Pipeline package, that lets external coding agents such as Claude Code, Cursor, VS Code and Windsurf control a running Unity Editor locally. It replaces the deprecated MCP server in the com.unity.ai.assistant package, is marked experimental, and works alongside Unity's skills-only plugin for Claude Code, Codex and Grok.
Pricing: Unity states that the CLI, MCP server and official plugin are free to use with no concurrency limits and need no Unity AI credits.
