# Unreal Official MCP Bridge

Bridge Epic's optional Unreal MCP into DCC MCP without redistributing the Epic
plugin. The engine plugin must already be installed, enabled, and serving on a
loopback HTTP endpoint.

## Workflow

1. Call `official_mcp_bridge` with `operation=status`.
2. Use `list_toolsets`, then `describe_toolset`, before calling an unfamiliar
   tool. Preserve Epic's tool names and schemas.
3. Use `call_tool` with the selected toolset and arguments. Do not issue
   overlapping mutating calls; Epic serializes tool invocations on the game
   thread.
4. Fall back to the normal DCC MCP Unreal skills when the official endpoint is
   unavailable or the running engine is older than 5.8.

The bridge accepts loopback HTTP endpoints only. Run it with `affinity:any`;
never block Unreal's game thread while making an HTTP request back into the
same editor process.
