Unity-AI Bridge

Unity-MCP is an open-source bridge between Unity game environments and AI assistants, enabling AI-assisted game development, automated testing, scene analysis, and runtime debugging. It implements a minimal set of six commands that allow executing C# code, querying game objects, and retrieving results asynchronously—all while respecting Unity's single-threaded execution model. The server handles long-running operations through a log ID system that maintains context across thread boundaries, allowing AI assistants to continue interaction while waiting for results from resource-intensive operations like running tests or performing scene analysis.
