Best for

Using an MCP client to inspect or automate publisher-documented Unreal Engine Editor workflows

Not ideal for

Final gameplay, rendering, build, or asset decisions without direct Unreal Editor validation

Avoid if

The project is not version controlled or automated Editor actions cannot be reviewed and reverted

Trade-offs

Direct Editor integration can shorten repetitive work, but Unreal project state is complex and plausible automated changes can still break assets, maps, code, or builds.

Evidence-backed setup

Install & Agents

Choose your MCP client. A client connects to the MCP server; the language model is selected inside that client. Only stored, source-backed configurations are shown.

Claude Code

Local stdio

MCP100 logic checked

claude mcp add unreal-mcp -- uv "--directory" "/absolute/path/to/unreal-mcp/Python" "run" "unreal_mcp_server.py"

The publisher connection details were combined with this client's official MCP transport configuration; installation was not executed by MCP100.

Verify safely: Restart Claude Code, confirm unreal-mcp tools are listed, and perform one read-only test with non-sensitive data.

Uninstall and revoke

Remove unreal-mcp from Claude Code, restart the client, remove any separately installed package, and revoke dedicated credentials if used.

Evidence & methodology

Publisher-documented setup is not the same as MCP100 execution testing. “MCP100 logic checked” means the stored configuration shape was reviewed, not that third-party MCP software was run.

🚀 Quick Start Guide

Prerequisites

Unreal Engine 5.5+
Python 3.12+
MCP Client (e.g., Claude Desktop, Cursor, Windsurf)

Sample project

For getting started quickly, feel free to use the starter project in MCPGameProject. This is a UE 5.5 Blank Starter Project with the UnrealMCP.uplugin already configured.

Prepare the project
- Right-click your .uproject file
- Generate Visual Studio project files
Build the project (including the plugin)
- Open solution (.sln)
- Choose Development Editor as your target.
- Build

Plugin

Otherwise, if you want to use the plugin in your existing project:

Copy the plugin to your project
- Copy MCPGameProject/Plugins/UnrealMCP to your project's Plugins folder
Enable the plugin
- Edit > Plugins
- Find "UnrealMCP" in Editor category
- Enable the plugin
- Restart editor when prompted
Build the plugin
- Right-click your .uproject file
- Generate Visual Studio project files
- Open solution (`.sln)
- Build with your target platform and output settings

Python Server Setup

See Python/README.md for detailed Python setup instructions, including:

Setting up your Python environment
Running the MCP server
Using direct or server-based connections

Configuring your MCP Client

Use the following JSON for your mcp configuration based on your MCP client.

{
  "mcpServers": {
    "unrealMCP": {
      "command": "uv",
      "args": [
        "--directory",
        "<path/to/the/folder/PYTHON>",
        "run",
        "unreal_mcp_server.py"
      ]
    }
  }
}

An example is found in mcp.json

MCP Configuration Locations

Depending on which MCP client you're using, the configuration file location will differ:

MCP Client	Configuration File Location	Notes
Claude Desktop	`~/.config/claude-desktop/mcp.json`	On Windows: `%USERPROFILE%\.config\claude-desktop\mcp.json`
Cursor	`.cursor/mcp.json`	Located in your project root directory
Windsurf	`~/.config/windsurf/mcp.json`	On Windows: `%USERPROFILE%\.config\windsurf\mcp.json`

Each client uses the same JSON format as shown in the example above. Simply place the configuration in the appropriate location for your MCP client.

Model Context Protocol for Unreal Engine

unreal-mcp

This project enables AI assistant clients like Cursor, Windsurf and Claude Desktop to control Unreal Engine through natural language using the Model Context Protocol (MCP).

⚠️ Experimental Status

This project is currently in an EXPERIMENTAL state. The API, functionality, and implementation details are subject to significant changes. While we encourage testing and feedback, please be aware that:

Breaking changes may occur without notice
Features may be incomplete or unstable
Documentation may be outdated or missing
Production use is not recommended at this time

🌟 Overview

The Unreal MCP integration provides comprehensive tools for controlling Unreal Engine through natural language:

Category	Capabilities
Actor Management	• Create and delete actors (cubes, spheres, lights, cameras, etc.)• Set actor transforms (position, rotation, scale)• Query actor properties and find actors by name• List all actors in the current level
Blueprint Development	• Create new Blueprint classes with custom components• Add and configure components (mesh, camera, light, etc.)• Set component properties and physics settings• Compile Blueprints and spawn Blueprint actors• Create input mappings for player controls
Blueprint Node Graph	• Add event nodes (BeginPlay, Tick, etc.)• Create function call nodes and connect them• Add variables with custom types and default values• Create component and self references• Find and manage nodes in the graph
Editor Control	• Focus viewport on specific actors or locations• Control viewport camera orientation and distance

All these capabilities are accessible through natural language commands via AI assistants, making it easy to automate and control Unreal Engine workflows.

🧩 Components

Sample Project (MCPGameProject) `MCPGameProject`

Based off the Blank Project, but with the UnrealMCP plugin added.

Plugin (UnrealMCP) `MCPGameProject/Plugins/UnrealMCP`

Native TCP server for MCP communication
Integrates with Unreal Editor subsystems
Implements actor manipulation tools
Handles command execution and response handling

Python MCP Server `Python/unreal_mcp_server.py`

Implemented in unreal_mcp_server.py
Manages TCP socket connections to the C++ plugin (port 55557)
Handles command serialization and response parsing
Provides error handling and connection management
Loads and registers tool modules from the tools directory
Uses the FastMCP library to implement the Model Context Protocol

FAQ

What can Model Context Protocol for Unreal Engine do?

MCP100's current stored description says: This project enables AI assistant clients like Cursor, Windsurf and Claude Desktop to control Unreal Engine through natural language using the Model Context Protocol (MCP).

Can Unreal MCP control actors, Blueprints, compilation, and builds?

MCP100's current stored permissions review says: Controls Unreal Editor actors, transforms, components, physics, Blueprints, node graphs, input mappings, compilation and build actions, and viewport state through a native TCP bridge.

Does Model Context Protocol for Unreal Engine work with Claude Code?

Yes. MCP100 found MCP100 logic checked setup for Claude Code. The current reviewed evidence also documents setup for Claude Desktop, Codex, VS Code, Cursor, and OpenCode. This reflects setup evidence, not an MCP100 execution test or a guarantee that a current client will connect.

Does Unreal MCP require authentication?

MCP100's current stored authentication review says: No API key, OAuth, token, or other authentication mechanism is documented in the reviewed README.

Is Unreal MCP suitable for production use?

MCP100's current stored risk review says: The publisher describes the project as experimental and not recommended for production. Its broad Editor and project mutation surface and native TCP bridge require a local-only boundary, version-controlled test project, and supervised changes. This MCP is not a security boundary or a general security certification.

Is this an official MCP?

github:chongdashu is listed as Community implementation in MCP100’s current evidence.
