Getting Started

Everything you need to start building with Cosindra.

Quick Start Guide

Step 1

Download the Cosindra companion app for your platform (Windows or macOS). Run the installer and create an account or log in.

Step 2

Click "Select Project" and point to your .uproject file. The app will automatically detect recent Unreal projects on your machine.

Step 3

The native C++ plugin is injected into your project's Plugins directory. Launch the editor — you'll see "CosindraMCP: Connected" in the output log.

Step 4

Type natural language commands in the chat. The AI understands Unreal Engine context — actors, Blueprints, materials, lighting, and more.

120+ tools organized by category. Here are the most commonly used.

spawn_actor \u2014 Spawn any actor class at a location

set_actor_transform \u2014 Move, rotate, scale actors

smart_spawn_actor \u2014 Spawn with mesh auto-assignment

spawn_blueprint_actor \u2014 Spawn from a Blueprint asset

delete_actor \u2014 Remove an actor from the scene

get_actor_properties \u2014 Inspect actor details

Instead of "add a character", say "spawn a third-person character at location 0,0,100 with the default mannequin mesh".

The AI remembers context. "Now add a material to it" works after spawning an actor — no need to re-specify.

For systems with 5+ nodes (weapon switching, health systems), describe the full behavior and let Blueprint AI generate the graph.

Ask the AI to "play in editor and check logs" to quickly verify your changes work in runtime.

Download the app and connect your Unreal project in under a minute.
