Inspect and safely edit Unreal Engine .uasset/.umap files using the BPX CLI tool. Analyze blueprints, properties, data tables, enums, materials, localization, and more with dry-run and backup support for asset management and refactoring.
OpenBPX: Blueprint Toolkit for Unreal Engine (bpx)
A safety-first CLI for reading and editing Unreal package assets (.uasset, .umap) without launching Unreal Editor.
BPX is designed for automation and scripting workflows where binary safety matters: unknown bytes are preserved, no-op round-trip stays byte-identical, and unsupported/high-risk operations fail explicitly.
Server-agnostic field manual for AI agents driving Unreal Engine 5.7 / 5.8 through MCP. Engine-level reflection gotchas, crash patterns, subsystem-specific quirks (Niagara, MetaSound, Materials, Lumen, UMG, audio), the Python-to-MCP data channel workaround, transport requirements, and verify-after-mutate patterns. Works with any MCP server that exposes UE5 functionality — Epic's official ModelContextProtocol plugin, custom servers, or anything else.
Build s&box games by talking to Claude. Bundles the Claude Bridge MCP server, a screenshot-driven game-dev workflow skill, and an optional sbox-game-dev specialist agent. The s&box editor addon must be installed separately (see README).
