Build, debug, test, package, and optimize Unreal Engine projects using C++, Blueprints, Automation Tests, Unreal Build Tool, and Automation Tool. Use for `.uproject` work and Unreal-specific runtime or editor issues.
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
# Unreal Engine ## Inspect first 1. Locate the `.uproject` file and read its engine association and enabled plugins. 2. Inspect `Source`, project plugins, `Config`, target files, module build files, and nearby tests. 3. Determine whether the behavior belongs in C++, Blueprint, data assets, editor tooling, or configuration. 4. Discover the installed editor and `RunUAT` or `RunUBT` entrypoint without assuming one platform path. Never text-edit `.uasset` or `.umap` files. Use source changes, configuration, commandlets, or an engine-aware editor workflow. ## Implementation rules - Keep gameplay rules out of actors and widgets when a subsystem, component, or plain testable type is a better owner. - Preserve reflection macros, module boundaries, object lifetime, replication authority, and thread affinity. - Treat asset references and gameplay tags as contracts; verify renames and redirects. - Avoid broad Blueprint reconstruction or resaves for a focused code change. - Do not rely on hot reload as final verification after changing reflected types. ## Verification Use the project's existing scripts when present. Otherwise select the narrowest engine-native checks: …

How to install
mdr add metaspartan/cybara/unreal-engine@sha256:d775fc14d1e28075The line at the top of this page pins the label git:20260907.0d9260e, 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.
