UEFN Ducky

Your UEFN Ducky.

Open source, community-driven, and infinitely extensible.

Bring every subscription and API key you own into one interface, infinitely expanding your tool set and letting your AI work in UEFN, Unreal Engine, Blender, Meshy.io and more!

How It Works

01

Install & Connect

Download the Windows app and pick a gateway. Cursor, OpenAI, and Claude come preloaded — connect through your IDE or straight to the API.

02

Link Your Project

Create or open a UEFN project, enable Python scripting in Island Settings, add the project to Ducky, then restart UEFN. Green glasses and a new row of editor buttons mean you’re connected.

03

Build with AI

Built for UEFN from the ground up. A single Ducky MCP server spans UEFN, Blender, and Meshy.ai, so your agent works across all of them — from any IDE that speaks MCP.

04

Build Your Workspace

Write your own UEFN tools around the way you actually work. If it doesn’t exist yet, build it in Ducky — every agent can call it the moment it’s saved.

Ducky missing something? It can build its own plugins.

Hey can you make a 3D top-down block editor plugin for yourself, that we can use to sketch out level designs and a button to import directly into UEFN.

What you get

One App. Every Tool.

Ducky is your local UEFN control panel. Install a plugin once, and every AI you work with gets it.

  • Knows Your Project

    Ducky reads your UEFN project directly. Active map layout, placed devices, Verse files, folder structure. You never paste context again.

  • Designed for UEFN and Verse

    Your co-pilot while you build. Keep working in your project while Ducky handles another task elsewhere in the level—writing Verse, placing devices, checking errors, and more.

  • One Connection, Every Tool

    Skills, tools, and MCPs connected to or installed in Ducky are available to any AI or IDE through one MCP connection. Skills and subskills load only when needed, reducing token usage and getting more value from your subscriptions and API keys.

  • Infinite Plugins

    Install Blender, Discord, Meshy, 3D AI Studio, themes, voice, and model gateways from the built-in Store. Ducky can even create new tools for you and your team to share.

  • A Team of Duckies

    Hand work to specialists like the Verse Coder, Level Designer, and VFX agent. Each agent gets a focused job to limit context poisoning, while Ducky shows every step, token, and result as the team works.

  • Any Model, Your Keys

    Use your own key, or use the Cursor, Claude, or Codex subscription you already pay for. Gateways for Anthropic, OpenAI, Google, Ollama, Kimi, and Grok. Keys stay encrypted on your machine.

Architecture

A Single Point of Truth

Every tool, skill, and MCP — including AI-generated ones — is reachable through UEFN Ducky's MCP. Connect once: Ducky and any IDE plugged into uefn-ducky share the same surface, always.
