Unity MCP Server
Gives your AI assistant read access to Unity projects without opening the Editor. Exposes tools to list build scenes, parse assembly definitions, find scripts by type or content, summarize scene hierarchies, inspect prefabs and materials, read input bindings, and pull project settings like player config, quality levels, and physics parameters. Works by reading the filesystem directly, so you can query project structure, dependencies, and asset metadata from Cursor, Claude Desktop, or any MCP client. Useful when you want an LLM to understand your Unity codebase, suggest refactorings across assemblies, audit scene composition, or generate documentation without context‐switching to the Editor.

Unity MCP Server
MCP server for Unity — Gives AI assistants structured access to your Unity project from any MCP-capable IDE or app. No Unity Editor required.
Your IDE talks to this server; the server reads your Unity project folder and answers with project info, build scenes, scripts, prefabs, and more — so the AI can help without opening the Editor.
Overview
- Editor-free — Reads only from the project filesystem.
- One server, many projects — Set
UNITY_PROJECT_PATHper project in your MCP config. - MCP-native — Works with any client that supports the Model Context Protocol (tools over stdio).
