Engine compatibility

UEAMCP supports UE 4.27.2 through UE 5.8.2 with a single source tree. Tools that need an engine feature declare a minimum version; on older engines they are simply absent from tools/list (the agent never sees a tool it cannot use).

Tools per engine (version 1.0)

The table is generated from the source (Tools/count_tools.py) and updated on every release.

Building for a version

The Fab listing includes binaries for each engine. From source, run BuildPlugin with the engine you target; no code changes are required. The compatibility layer (UeaCompat.h) isolates the API differences.
