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.…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# 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.

How to install

The exact contents, by fingerprint
mdr add ibrews/ue5-mcp/ue5-mcp@sha256:8387a260e52f81de

The line at the top of this page pins the label v3.3.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
