Sources and review

Checked against public documentation on . Suitability guidance is our editorial judgment; this is not a performance benchmark or an endorsement.

Best for

Unity developers who want an assistant in their IDE to act on the open editor, not just edit C# files.

Avoid if

You can't install Node.js on the machine; the server component requires it.

About MCP Unity

MCP Unity implements the Model Context Protocol for the Unity Editor. A Unity package bridges to a bundled Node.js MCP server, so assistants can execute menu items, select and modify GameObjects and query scenes, with MCP resources and prompts alongside the tools. It also adds Unity's package cache to VS Code-style workspaces to improve code intelligence for Unity packages.

MCP Unity is listed in this index written primarily in C#, with 2.0k stars on GitHub. Its latest recorded repository push was in October 2026; that is not an ASE editorial review date.

Before connecting: access and data

This record's specific permissions have not been reviewed by ASE. Read the publisher's documentation before copying setup or connecting.

  • List the accounts, files and services the enabled tools can read, change or execute. Check your actual credentials and discovered tools.
  • Use narrowly scoped credentials and read-only mode where supported. Review proposed writes before approving them; a generated configuration does not apply these limits for you.
  • Local launch is not local-only data processing. External services receive requests, and your client may pass tool results to its model provider. Check both destinations before sharing private data.
  • Keep keys and browser session files out of shared config, repositories and screenshots. Know how to disconnect the server and separately revoke its credentials or account sessions.
