Install

Unreal Engine MCP

claude mcp add unreal-engine-mcp -e UE_PROJECT_PATH='<UE_PROJECT_PATH>' -- npx -y unreal-engine-mcp-server@0.6.0-beta-f

Settings it needs

  • UE_PROJECT_PATHrequired · Your Unreal project folder or its .uproject file. The server reads the capability token from <project>/Saved/MCP/capability-token and the WebSocket port from the project settings.
  • MCP_AUTOMATION_CAPABILITY_TOKENsecret · Capability token to present to the editor. Only needed when the server cannot read the project folder, for example over LAN.
  • MCP_AUTOMATION_PORT · Editor WebSocket port. Default: the first Listen Ports entry in the project settings, else 8090.
  • MCP_AUTOMATION_HOST · Editor host to connect to. A LAN address also needs MCP_AUTOMATION_ALLOW_NON_LOOPBACK=true and Allow Non Loopback in the plugin settings.
  • MCP_AUTOMATION_ALLOW_NON_LOOPBACK · SECURITY: allow a non-loopback MCP_AUTOMATION_HOST. Enable only on a trusted network.
  • MCP_AUTOMATION_USE_TLS · Connect with wss:// instead of ws://.
  • MCP_ADDITIONAL_PATH_PREFIXES · Extra content roots to allow besides /Game, /Engine, /Script, /Temp and /Niagara, comma-separated. Example: /MyPluginContent/
  • MCP_CONNECTION_TIMEOUT_MS · How long to wait for the editor connection, in milliseconds.
  • MCP_REQUEST_TIMEOUT_MS · Overrides every per-capability request timeout, in milliseconds. Leave unset: each capability gets a budget that fits its cost.
  • MCP_AUTOMATION_MAX_MESSAGES_PER_MINUTE · Inbound messages per minute from the editor before the server disconnects.
  • LOG_LEVEL · Log level. Logs go to stderr.

Unity MCP

claude mcp add unity-mcp -- docker run -i --rm -e UNITY_MCP_PORT -e UNITY_MCP_PLUGIN_TIMEOUT -e UNITY_MCP_CLIENT_TRANSPORT docker.io/ivanmurzakdev/unity-mcp-server:0.17.1

Settings it needs

  • UNITY_MCP_PORT · Client -> Server <- Plugin connection port (default: 8080)
  • UNITY_MCP_PLUGIN_TIMEOUT · Plugin -> Server connection timeout (ms) (default: 10000)
  • UNITY_MCP_CLIENT_TRANSPORT · Client -> Server transport type: stdio or http (default: http)
