OpenClaw Unreal Plugin

version: 1.0.0

MCP skill for controlling Unreal Engine Editor via OpenClaw.

Connection Modes

Mode A: OpenClaw Gateway (Remote)

The plugin connects to OpenClaw Gateway via HTTP polling. Works automatically when Gateway is running.

Mode B: MCP Direct (Claude Code / Cursor)

The plugin runs an embedded HTTP server on port 27184. Use the included MCP bridge:

# Claude Code
claude mcp add unreal -- node /path/to/Plugins/OpenClaw/MCP~/index.js

# Cursor — add to .cursor/mcp.json
{"mcpServers":{"unreal":{"command":"node","args":["/path/to/Plugins/OpenClaw/MCP~/index.js"]}}}

Both modes run simultaneously.

Editor Panel

Window → OpenClaw Unreal Plugin — opens a dockable tab with:

  • Connection status indicator
  • MCP server info (address, protocol)
  • Connect / Disconnect buttons
  • Live log of tool calls and messages

Troubleshooting

Stale binaries / plugin not loading

Clear the build cache and restart the editor:

rm -rf YourProject/Plugins/OpenClaw/Binaries YourProject/Plugins/OpenClaw/Intermediate

Connection issues

  • Ensure OpenClaw Gateway is running: openclaw gateway status
  • Check the Editor Panel log for errors
  • Verify the MCP port is not blocked by firewall
