Unreal Official MCP Bridge

Enable and bridge Epic's optional Unreal MCP into DCC MCP without redistributing the Epic plugin. The engine plugin must be installed with the engine; this skill can enable it for the current project and configure its loopback HTTP endpoint.

Workflow

Call official_mcp_bridge with operation=status.
If status is unavailable on Unreal Engine 5.8+, obtain explicit permission to change project configuration, then call prepare_official_mcp. Enable NiagaraToolsets only when the task needs Niagara authoring.
When restart_required is true, restart the editor and verify the DCC MCP instance before retrying operation=status. Do not claim success from the configuration write alone.
Use list_toolsets, then describe_toolset, before calling an unfamiliar tool. Preserve Epic's tool names and schemas.
Use call_tool with the selected toolset and arguments. Do not issue overlapping mutating calls; Epic serializes tool invocations on the game thread.
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.
