Advanced Unity MCP Integration

What it is

A Unity Editor package and a Node.js MCP server that talk over a WebSocket, so an assistant can read the open scene, run C# in the Editor, watch the console and work with files in the project.

What you get

• Editor and scene state: the project and the editor, the current scene, and specific GameObjects in it — get_editor_state, get_current_scene_info, get_game_objects_info
• C# run directly in the Unity Editor, with the call waiting for the result — execute_editor_command
• Unity console logs, filtered, and a check that the Editor link is up — get_logs, verify_connection
• Project files read, written and edited, with a diff preview and a dry run for targeted edits — read_file, read_multiple_files, write_file, edit_file
• Directory listings and trees, file search and file metadata, with relative paths resolved against the Assets folder — list_directory, directory_tree, search_files, get_file_info
• Assets found by type, such as Material or Prefab, and every C# script in the project listed — find_assets_by_type, list_scripts

Requirements

Unity 2021.3 or later with the Editor open, and Node.js 18+ for the server. The Unity-side package installs through the Package Manager from the repository's git URL.
