Installation
From Fab
- Add the plugin to your library on Fab and install it to your engine version from the Epic Games Launcher (Library → Fab Library → Install to Engine).
- Open your project. Edit → Plugins → search Absolute MCP → enable → restart.
- On startup the Output Log shows:
LogUEAMCP: Display: Absolute MCP server listening at http://127.0.0.1:9321/uea-mcp
That is all. There is no window, no login and no configuration step.
From source
Copy the UnrealEngineAbsoluteMCP folder into <Project>/Plugins/ and open the project; the
editor compiles it (Visual Studio 2019 for 4.27, 2022 for 5.x).
