uMCP (Unity Editor)

This MCP server provides Unity game development automation by enabling AI assistants to directly control Unity Editor through a streamable HTTP interface running on localhost:7225. Built by mika-f using C# with Unity's Editor API, it implements a JSON-RPC protocol over server-sent events to expose Unity tools for asset management and testing operations, including GUID generation and input echoing for development workflows. The implementation features real-time command processing through Unity's main thread, automatic server lifecycle management tied to Editor sessions, and extensible tool registration through custom attributes, making it valuable for game developers who want AI assistance in automating Unity Editor tasks and integrating external tools with their Unity development pipeline.
