MCP for Unity is the most widely used Unity MCP server on GitHub. It runs a local server that connects your MCP client to the open Unity Editor, so the agent can create objects, change components, edit C# scripts and run Editor automation, instead of only editing files on disk.
Setup has three steps: add the package from the git URL, let the Configure All Detected Clients window write the MCP config for the agents it finds, then send a prompt.
Compared with other Unity options
- AI Game Developer (Unity-MCP) is a second community server that ships its own CLI and generates skills for your project.
- Unity official skills are prompts and workflows, not an MCP server. They pair well with either bridge.
Requirements
- Unity 2021.3 LTS to 6.x
- Python 3.10+ via uv
- Any MCP client
