UECortex is a native Unreal Engine MCP server and tool set that helps you connect Unreal Engine with AI tools like Claude. It lets you automate tasks in your project, cut down on manual work, and move faster when building scenes, blueprints, animations, and gameplay systems.
Use it to help with:
- Blueprint tasks
- C++ helper workflows
- Animation retargeting
- IK setup
- UE GAS tasks
- PCG workflows
- Project automation
Visit this page to download or access the latest version:
If the project provides a release file later, download that file from the same page and follow the steps below.
Before you start, make sure you have:
- A Windows PC
- Unreal Engine installed
- Enough free disk space for the app and your Unreal project
- A working internet connection
- Permission to run files on your computer
For best results, use a system that already runs Unreal Engine well.
Follow these steps to get UECortex running on your computer.
-
Open the download page: UECortex on GitHub
-
Look for the latest release, installer, or project files.
-
Download the file if one is listed.
-
If the file is in a ZIP folder, right-click it and choose Extract All.
-
Open the extracted folder.
-
Run the main app or setup file.
-
If Windows asks for permission, choose Yes.
-
Follow the on-screen steps until the app opens.
After the app is running, connect it to your Unreal project.
- Open Unreal Engine.
- Open the project you want to use.
- Start the UECortex server or tool from the app.
- Add the connection details in your AI tool or Unreal workflow, if needed.
- Test the link by asking the tool to run a small task.
If you use Claude or another LLM tool, keep both tools open while you test the first connection.
UECortex is built to support common Unreal Engine tasks such as:
- Create or edit Blueprints
- Help write C++ code
- Assist with animation retargeting
- Work with IK rigs and controls
- Support UE GAS setup
- Help with PCG graph tasks
- Speed up repeat project work
- Make simple project changes from text prompts
This makes it useful when you want help with routine steps in a project.
After setup, you may see files like these:
- App files for UECortex
- Config files
- Logs
- Plugin or tool folders
- Example project files
- Readme or help files
Keep these files together in one folder so the app can find what it needs.
A simple way to use UECortex looks like this:
- Open UECortex.
- Open your Unreal project.
- Connect your AI tool.
- Ask for a task.
- Review the result in Unreal Engine.
- Save your work.
Start with small tasks first, such as checking a Blueprint or making a small code change. That helps you confirm the setup works.
If the app does not start:
- Check that you extracted the files first
- Run the app as an administrator
- Make sure Unreal Engine is installed
- Restart your computer and try again
If the connection does not work:
- Confirm the server is running
- Check that the app and Unreal project are open
- Make sure your AI tool has the right connection details
- Close and reopen both apps
If Unreal Engine does not respond as expected:
- Open the correct project
- Confirm the plugin or tool files are in the right place
- Check for blocked files in Windows security
- Try again after a fresh restart
Windows may ask for permission the first time you run the app. This is normal for tools that work with local files and developer apps. Only run the files you downloaded from the link above and from sources you trust.
Use UECortex with clear, small requests. For example:
- Create a simple Blueprint for a door
- Check this C++ class for errors
- Help retarget this animation
- Set up an IK rig for this character
- Build a PCG rule for trees
- Add a basic gameplay ability
Simple requests are easier to review and fix.
UECortex fits into workflows for:
- AI-assisted development
- Unreal Engine automation
- Blueprint support
- Code generation
- Animation work
- Retargeting animations
- IK systems
- UE GAS
- UE PCG
- Native engine tools
Before you use it for real work, confirm this:
- UECortex opens without errors
- Unreal Engine starts normally
- Your project loads
- The connection to your AI tool works
- A small task returns the result you expect
If all five items work, you are ready to use it in your project
Keep these items in one place:
- The UECortex app or build files
- Any config files
- Any example setup files
- Your Unreal project files
- Any notes you make during setup
That makes it easier to repeat the setup later
If you need the file later, use this link:
- Use a folder with a short path, like
C:\UECortex - Avoid moving files after setup
- Keep Unreal Engine updated
- Keep your AI tool updated
- Use the same project folder each time
