Cross-platform CLI tool for AI Game Developer (Skills & MCP). Full AI develop and test loop. Efficient token usage, advanced tools. Creates Unity
Unity MCP server exists for a simple reason — assistants are far more useful when they can act on Unity directly instead of describing what you should do. Cross-platform CLI tool for AI Game Developer (Skills & MCP). Full AI develop and test loop. Efficient token usage, advanced tools. Creates Unity project, installs plugins, configures tools, and manages HTTP connection with Unity Editor.
Unity MCP is an AI-powered game development assistant for Editor & Runtime. Connect Claude, Cursor, & Windsurf to Unity via MCP. Automate workflows, generate code, and enable AI within your games.
Once Unity is connected, these are the calls the assistant has available:
assets-copy — Copy the asset at path and stores it at newPathassets-create-folder — Creates a new folder in the specified parent folderassets-delete — Delete the assets at paths from the projectassets-find — Search the asset database using the search filter stringassets-find-built-in — Search the built-in assets of the Unity Editorassets-get-data — Get asset data from the asset file including all serializable fields and propertiesassets-material-create — Create new material asset with default parametersassets-modify — Modify asset file in the projectassets-move — Move the assets at paths in the project (also used for rename)assets-prefab-close — Close currently opened prefabassets-prefab-create — Create a prefab from a GameObject in the current active sceneassets-prefab-instantiate — Instantiates prefab in the current active sceneThe server ships on npm as unity-mcp-cli, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Unity's toolset — assets-copy, assets-create-folder, assets-delete and 11 more — is a fair guide to whether it matches your workflow. It is maintained by GitHub Actions; worth a glance at recent repository activity before you build anything load-bearing on it.
