About Unity MCP

Unity MCP is an MCP server published by shiranui-isuzu.dev. Unity Editor automation for AI agents: scenes, prefabs, assets, shaders, Timeline, tests, builds.

It runs on your own machine: your AI client starts it from the NuGet package IsuzuUnityCli at version 4.4.2.

It asks for no keys or passwords.

Version 4.4.2 was published on 17 September 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 7 automated checks on registry metadata: 4 pass, 0 warn, 0 fail, 3 info. How we check.
