97 MCP tools for Unreal Engine
gengine lets Claude and other AI models see, modify, and build inside your Unreal Editor. Spawn actors, create Blueprints, modify materials, inspect animations — all through natural language.
Free tier includes 10 read-only tools. No credit card required.
// You type natural language. gengine controls Unreal Editor.
// "Spawn a directional light and angle it for golden hour"
await unreal_world({
operation: "spawn_actor",
params: {
class_path: "/Script/Engine.DirectionalLight",
name: "GoldenHourLight",
rotation: { pitch: -25, yaw: 210 }
}
});
// "Create a health component Blueprint"
await unreal_blueprints({
operation: "create",
params: {
name: "BP_HealthComponent",
parent_class: "ActorComponent",
path: "/Game/Components"
}
});
// "Set the water material to translucent blue"
await unreal_input_materials({
operation: "set_material_parameters",
params: {
asset_path: "/Game/Materials/MI_Water",
parameters: {
BaseColor: { r: 0.1, g: 0.3, b: 0.8 },
Opacity: 0.6
}
}
});6 domains. 97 operations. One plugin.
Every tool operates on live editor state — not serialized files. Your AI model gets real-time access to actors, assets, Blueprints, and more.
Actors & World
Spawn, move, and delete actors. Set properties, capture the viewport, read output logs, and run console commands on the live editor.
Assets
Search the asset registry, inspect dependencies, create and duplicate assets, rename, move, and manage the full asset lifecycle.
Blueprints
Create Blueprint classes, add variables and functions, place and connect nodes, set pin values, and compile — all programmatically.
Animation
Create state machines, add states and transitions, assign animations, set durations, batch operations, and validate Animation Blueprints.
Characters
List and inspect characters, configure movement parameters, create data assets, update stat tables, and manage character data.
Input & Materials
Create input actions and mapping contexts, build material instances, set material parameters, and wire up Enhanced Input.
Built for production use
Security hardened, performance tuned, and designed for professional game development workflows.

Task queue (4 concurrent) │Three-tier safety system
ReadOnly, Supervised, and Unrestricted modes with server-side enforcement. Destructive operations require explicit confirmation. Fails closed by default.
Parallel task execution
Up to 4 concurrent MCP operations on the editor task queue. Read-only tools run in parallel; modifying tools are safely sequenced per-object.
Web chat panel
Built-in web UI with topic tabs, persistent memory, @ asset mentions, image paste, and provider selection. Talk to your editor from the browser.
In-editor command center
Tool browser, task monitor, activity feed, and diagnostics panel — all inside the Unreal Editor. See exactly what your AI is doing.
UE 5.7 context injection
Accurate API documentation injected into every tool call. Your AI model gets the right UPROPERTY specifiers, function signatures, and engine idioms.
Bring Your Own Key
Use Anthropic, OpenAI, Ollama, LM Studio, or any OpenAI-compatible provider. Your API keys, your models, your choice.
Simple, transparent pricing
