Unreal Engine Mcp
Bridges Claude to Unreal Engine 5 through a native C++ plugin that exposes 17 automation tools over a local GraphQL endpoint. You get asset operations (import, duplicate, rename), actor spawning and transforms, PIE session control, Sequencer timeline manipulation, and Niagara particle authoring. The plugin runs inside UE's editor process on port 8091 by default, handling Blueprint graphs, animation state machines, level streaming, and console command execution with safety blocks. Ships as an npm package that talks to the C++ bridge you drop into your project's Plugins folder. Aimed at developers automating repetitive editor tasks or prototyping game logic conversationally instead of clicking through menus. Supports UE 5.0 through 5.7 with graceful degradation when the editor isn't running.

Install
From registry metadata$ npx add-mcp unreal-engine-mcp-server --name unreal-engine-mcp --env 'UE_PROJECT_PATH=${UE_PROJECT_PATH}' --env 'MCP_AUTOMATION_CAPABILITY_TOKEN=${MCP_AUTOMATION_CAPABILITY_TOKEN}'Run in your terminal. add-mcp asks which agents to add it to, then asks for each value it needs. Add -g to install it for every project.
Review the command, arguments and environment values before installing. MCP servers run with your local permissions.
