Unreal Engine MCP Python Bridge Plugin is an Unreal Engine plugin that implements the Model Context Protocol (MCP) server. It allows MCP clients, such as Anthropic’s Claude, to access the full Unreal Engine Python API, enabling AI-assisted development and automation within Unreal Engine projects.
How to use Unreal Engine MCP Python Bridge Plugin?
Install the plugin from the Fab store or build from source. After enabling the plugin in Unreal Engine, click the “Start MCP Bridge” toolbar button to start a socket server on 127.0.0.1:9000. Configure your MCP client (e.g., Claude) to use unreal_mcp_client.py as the server script, then attach the client to the running bridge.
