Unity MCP server & Claude connector

Does Unity have an official MCP server or Claude connector?

Official

As of October 2026, Unity's official MCP route is the Unity CLI's 'unity mcp' command, documented on docs.unity.com as the replacement for the in-Editor MCP server in the AI Assistant package, which Unity has deprecated. The CLI is free and local, and needs Unity 6.0 LTS or later to drive an Editor. Unity's May 2026 blog still calls the older server open beta.

FAQ

Does Unity have an official MCP server?

Yes. Unity's current route is the Unity CLI's 'unity mcp' command (docs.unity.com). The older in-Editor server in the AI Assistant package is deprecated.

Is the Unity MCP server deprecated?

The in-Editor server (com.unity.ai.assistant) is deprecated per docs.unity.com, which gives no date. The CLI's MCP mode is not part of the deprecation. Unity's May 2026 blog describing it as open beta predates that notice.

How do I connect Claude to Unity?

Per Unity's docs: install the Unity CLI, run 'unity pipeline install', then 'unity mcp configure claude'. Driving a running Editor needs Unity 6.0 LTS or later.

Do third-party Unity MCP packages still work?

Unity's CLI page says third-party MCP packages installed from GitHub are unaffected by the deprecation.

Does it need a paid plan?

Unity's docs say the CLI is free and needs no Unity AI subscription. The deprecated in-Editor server's May 2026 blog listed an active trial or subscription to the Unity AI beta.
