The publisher's own command. Not a PlugMCP endpoint.

Local command
npx -y [email protected]
Credentials from the publisher
  • UE_PROJECT_PATH β€” 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_TOKEN β€” Capability token to present to the editor. Only needed when the server cannot read the project folder, for example over LAN.
  • MCP_AUTOMATION_PORT β€” Editor WebSocket port. Default: the first Listen Ports entry in the project settings, else 8090.
  • MCP_AUTOMATION_HOST β€” 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 β€” SECURITY: allow a non-loopback MCP_AUTOMATION_HOST. Enable only on a trusted network.
  • MCP_AUTOMATION_USE_TLS β€” Connect with wss:// instead of ws://.
  • MCP_ADDITIONAL_PATH_PREFIXES β€” Extra content roots to allow besides /Game, /Engine, /Script, /Temp and /Niagara, comma-separated. Example: /MyPluginContent/
  • MCP_CONNECTION_TIMEOUT_MS β€” How long to wait for the editor connection, in milliseconds.
  • MCP_REQUEST_TIMEOUT_MS β€” 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 β€” Inbound messages per minute from the editor before the server disconnects.
  • LOG_LEVEL β€” Log level. Logs go to stderr.
