πŸ“– About This Skill

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 β€” add to .cursor/mcp.json

{"mcpServers":{"unreal":{"command":"node","args":["/path/to/Plugins/OpenClaw/MCP~/index.js"]}}}

Both modes run simultaneously.
