Claude Code CLI integration for Unreal Engine 5.7 - Get AI coding assistance with built-in UE5.7 documentation context directly in the editor.

> Supported Platforms: Windows (Win64), Linux, and macOS (Apple Silicon). Claude Opus 4.7 and its Claude Code release supported.
Overview

UnrealClaude integrates the Claude Code CLI directly into the Unreal Engine 5.7 Editor and runs a MCP server for access to other coding agents.

Key Features:
- Native Editor Integration - Chat panel docked in your editor with live streaming responses, tool call grouping, and code block rendering
- MCP Server - 20+ Model Context Protocol tools for actor manipulation, Blueprint editing, level management, materials, input, and more
- Dynamic UE 5.7 Context System - The MCP bridge includes a dynamic context loader that provides accurate UE 5.7 API documentation on demand
- Blueprint Editing - Create and modify Blueprints, Animation Blueprints, state machines (Few bugs still, don't rely on fully)
- Level Management - Open, create, and manage levels and map templates programmatically
- Asset Management - Search assets, query dependencies and referencers
- Async Task Queue - Long-running operations won't timeout
- Script Execution - Claude can write, compile (via Live Coding), and execute scripts with your permission
- Session Persistence - Conversation history saved across editor sessions
- Project-Aware - Automatically gathers project context (modules, plugins, assets) and is able to see editor viewports
- Uses Claude Code Auth - No separate API key management needed

Prerequisites
