Field manual for driving Unreal Engine 5.7 / 5.8 through MCP. Engine-level gotchas, silent-fail edges, crash patterns, and the call sequences that actually work — applicable regardless of which MCP server you're using (Epic's official ModelContextProtocol plugin, custom servers, or anything else). Auto-trigger when Unreal Engine MCP tools are detected in a session, or when the user mentions Unreal Engine, UE5, Blueprints, Niagara, MetaSound, materials, or any UE editor automation workflow. This skill contains hard-won knowledge from real debugging sessions — most entries trace back to an actua

# ue5-mcp — Field manual for driving Unreal Engine 5 via MCP

Engine-level wisdom an LLM needs to drive UE5 through an MCP server without
faceplanting on UE's silent-fail edges. This skill is **server-agnostic**:
the gotchas, patterns, and identifiers documented here apply whether you're
connected to Epic's official `ModelContextProtocol` plugin (UE 5.8+) or any
other MCP server that exposes UE5 functionality.

What this skill *isn't*: a list of commands for any particular MCP server.
Each server publishes its own tool catalogue — ask the server with
`tools/list` for what it actually exposes. This skill covers what bites you
*after* you know the tool names.

## 1. Session checklist — read before you write

UE5 is a structured-asset editor. The agent that wins is the one that reads
state before mutating it.

1. **Always dump the asset before editing it.** Blueprint, material, Niagara
   system, widget, level — every MCP server worth its salt exposes a
   `dump_*` / `inspect_*` / `read_*` family. Use it. Editing a graph
   without first knowing what's there creates broken connections, duplicate
   nodes, and unrecoverable corruption faster than anything else.
2. **Discover before assuming.** Call `tools/list` once on connect, cache it,
   and use it to figure out which tools your server actually exposes.
   Different servers wrap UE5 differently; recipes from this manual that
   reference a generic capability (e.g., "dump the Blueprint graph") will
