Unreal Engine MCP (Flopperam / Aura)

CommunityRemoteby Aura (formerly Flopperam), communityfreemiumverified Oct 14, 2026

Third-party Unreal MCP for UE 5.5+, with a hosted 50-tool option Epic's server has no answer to.

What it does

Two modes: a hosted 'Flop MCP' over streamable HTTP with 50+ tools across Blueprint authoring, materials, VFX, animation, landscape, AI/behaviour trees, cinematics and PCG, and an open-source local Python server plus C++ plugin with a smaller scene-level toolset. The reason to reach for it over Epic's first-party server is engine coverage — UE 5.5 through 5.7 — and Blueprint authoring depth.

Auth: api_key — https://flopperam.com/account (hosted mode); local mode is free but requires compiling the bundled UnrealMCP C++ plugin

Field notes

Ownership changed: the repo's README and description state Flopperam has been acquired by Aura and point ongoing development at tryaura.dev. Re-checked 14 Oct 2026: 1.1k stars, last commit still Jun 26 2026 (the one that moved the Aura banner to the top of the README) — three and a half months without code, so treat the open-source half as parked. The README's licence line says MIT but the repo still contains no LICENCE file and GitHub's licence API returns 404, so the grant is unconfirmed. The hosted endpoint still answers 401 unauthenticated, so it is alive and key-gated. Aura's product page now markets an agent for Unreal 5.4+ and Unity 5/6, working in the editor, Claude Code, Codex and IDEs, with a two-week free trial — still without mentioning MCP or this endpoint, which is the direction the funding is going. Landscape: Epic ships a first-party server for UE 5.8 (unreal-mcp-epic); chongdashu/unreal-mcp is still the most-starred at 2.1k but has not been pushed since Apr 2025; ChiR24/Unreal_mcp (928 stars, MIT, pushed Oct 13 2026, TypeScript + a C++ Automation Bridge plugin) is the most actively maintained community option.
