Claude Desktop
Connect Claude Desktop to NeoStack AI.
Claude Desktop connects to your editor through a small extension file (.mcpb). Install it once and it finds your running editor by itself. No ports, no tokens, no config.
You need the NeoStack AI plugin version 3.1.8 or newer in your project.
Install
- Download the file for your machine:
| Platform | Download |
|---|---|
| Windows x64 | neostack-connect-win64.mcpb |
| macOS Apple Silicon | neostack-connect-macos-arm64.mcpb |
| macOS Intel | neostack-connect-macos-x64.mcpb |
| Linux x64 | neostack-connect-linux-x64.mcpb |
-
Double-click it, or use Claude Desktop → Settings → Extensions → Install Extension…
-
The Unreal project directory setting is optional. Leave it blank. Only set it if you often have several editors open and want Claude pinned to one project.
Try it
Open your project in Unreal, then ask Claude:
Use the unreal tool to print “hello from claude desktop”.
If the message shows up in the editor’s Output Log, you’re done.
If it doesn’t connect
Just ask Claude to “run unreal_status”. It will tell you what the bridge found and what’s wrong.
| Problem | Fix |
|---|---|
| No Unreal tools showing | Open your project. The tools appear a few seconds later, no restart needed. |
| “No running Unreal editor found” | Check the NeoStack AI plugin is enabled and is 3.1.8 or newer. |
| “More than one editor is running” | Ask Claude to select a project, e.g. “select the ShooterGame project”. |
Notes
- Claude.ai in the browser can’t connect to local apps. Use Claude Desktop or Claude Code.
