English | 日本語

Provides integration of any AI agent (Gemini CLI, Claude Code, Codex CLI, etc.) with the Unity editor using Agent Client Protocol(ACP).

Overview

Unity Agent Client is an editor extension that uses the Agent Client Protocol (ACP) proposed by Zed to enable any AI agent to run on the Unity editor.

Features

• Integrate any AI agent into the Unity editor
• Supports all AI agents compatible with ACP (Gemini CLI, Claude Code, Codex CLI, etc.)
• Utilize assets and editor information as context
• Provides a built-in MCP server

What's Agent Client Protocol?

Agent Client Protocol is a new protocol proposed by Zed to connect AI agents and code editors. It is a protocol based on JSON-RPC and is designed with integration with MCP (Model Context Protocol) in mind.

Zed enables the integration of external AI agents into editors using ACP. Unity Agent Client adopts a similar approach, implementing an ACP Client as an editor extension, allowing any AI agent to run on the Unity editor.

Currently, Gemini CLI provides experimental support (--experimental-acp), and Zed's adapters enable ACP compatibility for Claude Code, Codex CLI, and others. A list of AI agents supporting ACP can be found at the following page:

Why not Unity AI?

From Unity 6.2 onwards, the official Unity AI can be used. So why use Unity Agent Client?

Unity AI uses models provided by Unity, which means users cannot choose the optimal model
