UEFN 제어 (Portnite 용 Unreal Editor) 모델 Context 프로토콜을 통해 Claude Code에서.

• 110 도구: 배우, 자산, 레벨, 뷰포트, 자료, 나이아가라, 애니메이션, 정적 메쉬, 데이터 테이블, 자산 검증, 장치 @editable 배선, Play-In-Editor 제어, StaticMeshActor scatter, Verse source introspection, Verse compile/push, Verse code 탐색, UEFN 세션 상태 / 발사, 그리고 arbitrary Python 실행
• **영 C++ 컴파일 ** - 순수 파이썬, UEFN 버전의 작품 -Main-thread safe - 모든 unreal.* 편집기 tick 콜백을 통해 파견된 호출
• Autostart — 청취자는 프로젝트가 열릴 때 시작한다 (Auto-start 참조)
• ** 충돌 복구 ** - UEFN 세션 도구는 충돌 후 UEFN 편집기 상태를 읽고 UEFN을 읽습니다. UEFN 세션과 충돌 복구를 참조하십시오.
• ** 입력 시뮬레이션 없음 ** - 서버는 마우스 또는 키보드 입력을 결코 보내지 않습니다; undo가 태그 실험에 하드 도구

0.5.0의 새로운 기능

• UEFN 세션 (uefn_session.py, 3개의 도구): uefn_status] (편집 로그, 프로세스 및의 읽기 전용 상태 포트), uefn_launch_project (start UEFN, 열린 프로젝트, 청취자를위한 대기; 충돌보고자를 왼쪽으로 중지 할 수 있습니다

UEFN MCP Server

Control UEFN (Unreal Editor for Fortnite) from Claude Code via the Model Context Protocol.

Claude Code    MCP Server (mcp_server.py)    Listener (uefn_listener.py, inside UEFN)
                                   |--TCP 127.0.0.1:1962-->  UEFN VerseWorkflowServer   (verse_compile / verse_status / verse_push)
                                   |--stdio------------->  verse-lsp.exe                (verse_symbols / verse_hover / ...)

• 110 tools: actors, assets, levels, viewport, materials, Niagara, animations, static meshes, data tables, asset validation, device @editable wiring, Play-In-Editor control, StaticMeshActor scatter, Verse source introspection, Verse compile/push, Verse code navigation, UEFN session status / launch, and arbitrary Python execution
• Zero C++ compilation — pure Python, works across UEFN versions
• Main-thread safe — all unreal.* calls dispatched via editor tick callback
• Autostart — the listener starts by itself when a project opens (see Auto-start)
• Crash recovery — the UEFN session tools read the editor state and relaunch UEFN after a crash; see UEFN session and crash recovery
• No input simulation — the server never sends mouse or keyboard input; tools that are hard to undo are tagged experimental

What’s new in 0.5.0

• UEFN session (uefn_session.py, 3 tools): uefn_status (read-only state from the editor log, processes and ports), uefn_launch_project (start UEFN, open a project, wait for the listener; can stop a crash reporter left over from a crash), uefn_set_load_on_startup. They send no mouse or keyboard input: when UEFN stops on the HUB, the user opens the project.
• [experimental] tag: 7 tools that are hard to undo or act outside the open level ask the user to confirm before each call. See Experimental tools.
• setup.ps1: one idempotent setup step for a new machine (-DryRun).
• Safety fixes (listener protocol 0.3.3): rotations are named axes {"pitch", "yaw", "roll"} (a documented [pitch, yaw, roll] list used to be applied as [roll, pitch, yaw]); the staticmesh_* tools stop calling the getters that crash UEFN 42.20. See Conventions.

What’s new in 0.4.0

A community fork was merged into this repo: 79 new tools (materials, Niagara, animation, static meshes, asset management, data tables, validation, screenshots, device @editable fields, Play-In-Editor, scatter, Verse
