unreal-mcp
Enable AI assistant clients like Cursor, Windsurf and Claude Desktop to control Unreal Engine through natural language using the Model Context Protocol (MCP).
No outside reports on file
Since this tool gives AI direct control over your Unreal Engine project and files, only use it in isolated development environments and never with untrusted prompts or data.

About Unreal MCP
This tool lets AI assistants like Claude Desktop and Cursor control Unreal Engine (a video game and graphics software) by typing instructions in plain English instead of writing code. It uses the Model Context Protocol to send commands between the AI and the game engine.
Who it’s for
Game developers and 3D artists who want to speed up work in Unreal Engine by talking to an AI assistant instead of clicking menus. This is useful for prototyping, automating repetitive tasks, and exploring ideas quickly.
Alternatives
- Unreal Automation Tool: Official scripting built into Unreal Engine for automation tasks without AI. - Blueprint Visual Scripting: Unreal's native visual programming system for game logic. - Python Editor Scripting: Unreal supports Python scripts for automating engine tasks directly. - Other game engine AI tools: Similar MCP connectors for Unity or other engines (check their security first).
Setup
Check these steps against the project’s own instructions before running anything.
Follow the project's README on GitHub for installation and setup instructions specific to your system and Unreal Engine version.

Risks to watch for
- Direct engine control: The AI can execute commands in Unreal Engine with the same permissions as the user running it, potentially modifying or deleting project files. - Malicious prompts: An attacker could trick the AI into running harmful commands by hiding instructions in project files, dialogue, or data the AI reads. - Information leakage: The AI might share sensitive project details, file paths, or credentials if asked or if they appear in engine logs sent back to the AI. - Version mismatches: Using an outdated or incompatible version of Unreal Engine with this tool could cause crashes or unexpected behavior. - Unverified updates: The tool is a community project with 2,100 GitHub stars but no visible npm ecosystem adoption; updates should be checked carefully before installing.
How to lower the risk
Least-privilege permissions
- Run this only on a dedicated development machine, never on shared or production systems.
- Store Unreal Engine projects in a folder where accidental deletion won't harm critical work.
Network isolation
- Restrict network access from the AI assistant to only your local Unreal Engine instance if possible.
- Avoid running this tool on public or cloud instances without strong access controls.
Monitoring
- Log all commands the AI sends to Unreal Engine and review them regularly.
- Watch for unexpected file changes or project modifications after using the tool.
Red flags to watch for
- The AI suddenly suggesting commands you didn't ask for or that seem unrelated to your goal.
- Slow performance or crashes after enabling this tool (may indicate resource conflicts).
- Error messages from Unreal Engine that mention security or permission issues.
