Native Unreal 5.8 Tools

Native Unreal 5.8 Tools documentation.

Official - Unreal Engine 5.8

The actions on this page wrap Unreal's native AI Toolset Registry (the plugin behind Unreal's own MCP server). Each one is a declared ue-mcp action inside the matching category: it states what it does to the editor, declares its own parameters, and goes through the same guards, locks and dispatch as every other action here. Pass a tool's arguments as ordinary top-level parameters, or as input when you prefer. Requires UE 5.8+ with the ToolsetRegistry plugin (and the toolset plugins you want) enabled. The epic category discovers the live registry (status / list_toolsets / describe_toolset / call_tool).

ue-mcp currently wraps 824 official tools across 52 toolsets, grouped below by the ue-mcp category they surface in. Domains ue-mcp has no native handlers for still get their own category (dataflow, conversation); only the registry's own meta-tooling lives under epic.
