## 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](https://agentclientprotocol.com) 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](https://unity.com/products/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
