Unreal_mcp
A comprehensive Model Context Protocol (MCP) server that enables AI assistants to control Unreal Engine through the native C++ Automation Bridge plugin. Built with TypeScript and C++.
No outside reports on file
This tool gives AI direct control over Unreal Engine internals, so use it only in isolated development environments with restricted file access and careful monitoring of what commands the AI is asked to run.
Based on public adoption and transparency signals as of Oct 23, 2026. Our opinion, not a code audit or security guarantee.

About Unreal_mcp
This is a connector that lets AI assistants send commands to Unreal Engine (a game and 3D software platform) through a plugin system. It translates AI requests into C++ instructions that the Unreal Engine automation tools can execute, letting the AI control engine features like asset creation or project settings.
Who it’s for
Game developers, 3D artists, and software teams using Unreal Engine who want AI assistants to help automate repetitive engine tasks. It's most useful for people comfortable with technical setup and the TypeScript/C++ integration it requires.
Alternatives
- UE Blueprints visual scripting (built into Unreal, no AI needed)
- Unreal Editor Python API (lets Python scripts control the editor, more established)
- Custom REST API wrapper (build your own engine control interface with standard tools)
- Other game engine connectors (similar MCP servers for Unity or Godot if using different engines)
Setup
Check these steps against the project’s own instructions before running anything.
Follow the project's README for installation steps. The project is hosted on GitHub and appears to require manual setup connecting the TypeScript server to the Unreal Engine plugin system.

Security reports
No reports found for this package in our research (last checked 2026-10-29).
Risks to watch for
- Engine access: The connector can execute arbitrary Unreal Engine commands, potentially modifying project files, deleting assets, or exposing source code if misconfigured.
- File system exposure: AI can read and write files through the engine's automation tools, creating risk of data theft or corruption.
- Deceptive prompts: An attacker could craft prompts that trick the AI into executing harmful engine operations under the guise of normal automation.
- Plugin vulnerabilities: Since this uses a native C++ plugin, bugs or unpatched flaws could let attackers run code with engine-level permissions.
- No built-in sandboxing: The connector appears to lack isolation between AI requests and actual engine execution, meaning harmful commands run immediately.
How to lower the risk
Least-privilege permissions
- Run the engine and connector on a dedicated local machine, never on a shared server.
- Limit the plugin's file access to only project folders, not system directories.
Network isolation
- Keep the AI system and Unreal Engine on the same machine or closed network only.
- Never expose the connector port to the internet or untrusted networks.
Monitoring
- Log all commands the AI sends to Unreal Engine and review them regularly.
- Watch for unusual asset modifications or file access patterns.
Red flags to watch for
- Prompts asking the AI to modify system files or install software.
- Requests to execute engine commands without clear human approval.
- Unexpected file reads or writes outside your project folder.
