Provides tools for interacting with Unreal Engine 5 via its Web Remote Control interface, enabling real-time bidirectional control, scene and asset manipulation, C++ code injection and compilation, automated lighting builds, and advanced viewport management.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@UE5-MCP-Server spawn a circle of 10 cubes at the origin"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
This project is a lightweight, high-performance server application based on the Model Context Protocol (MCP). It serves as an ultimate bridge between Large Language Models (like Claude) and Unreal Engine 5 (UE5).
By integrating directly with UE5's native Web Remote Control interface, this project empowers AI to interact directly with the underlying Unreal Engine. AI can not only query and modify assets within the engine but also dynamically inject C++ code, compile core modules, and manipulate all elements within the scene with high-level privileges.

🔌 Real-time Bidirectional Remote Control: Deep integration with UE5 Web Remote Control via HTTP/JSON protocols, enabling zero-latency instruction execution.
🧱 C++ Blueprint Code Injection & Compilation: Supports AI in writing native C++ Actors and Blueprint Function Libraries in the background, and triggering cross-process Live Coding compilation with a single command.
🎮 Automated Scene & Viewport Management: Includes a suite of advanced tools, such as:
ue5_spawn_actors_batch: High-performance batch generation and alignment of objects (e.g., spawning circles or array matrices).
ue5_pilot_actor: Takes over the editor camera, enabling AI-level automated cinematic movements and scene touring.
ue5_build_lighting: Automated scene lighting builds.
🎨 Automated Asset Assembly: Supports dynamic retrieval of materials and automatic assignment to scene meshes, enabling one-click material swapping and beautiful level generation.
Ensure the Web Remote Control plugin is enabled in Unreal Engine, and start the server (default port: 30010).
Run npm install in the root directory of this project to install dependencies.
Run npm run build to build the project.
Connect to UE5 by mounting this project in your MCP client configuration.

Unreal Engine 5 Web Remote Control: Unreal Engine Native Open API
Generated with AI assistance. Bridging the gap between Language Models and Game Engines.
Builds light maps and reflection captures for the level. NOTE: This may take a long time and block the editor.
Inputs: no named parameters.
Calls a UFUNCTION on a UObject via the Web Remote Control API. IMPORTANT: Some functions on component sub-objects (e.g., LightComponent, RootComponent) are marked 'unavailable remotely'. Use actor-level functions like SetActorScale3D, SetActorTransform instead.
Inputs: objectPath (required), functionName (required), parameters, generateTransaction.
Deletes an asset from the Content Browser.
Inputs: assetPath (required).
Removes an actor from the current level by its object path.
Inputs: actorPath (required).
Duplicates an asset in the Content Browser.
Inputs: sourceAssetPath (required), destinationAssetPath (required).
Ejects the currently piloted actor in the editor viewport.
Inputs: no named parameters.
Executes an Unreal Engine console command in the editor. NOTE: UE5 does not return success/failure for console commands — the response will be empty even if the command is invalid.
Inputs: command (required).
Gets all actors currently in the active editor level. Returns an array of actor object paths.
Inputs: no named parameters.
Gets the value of a UPROPERTY on a UObject. NOTE: Component properties (e.g., RootComponent, LightComponent) are often unavailable remotely. Use ue5_call_function with getter functions instead.
Inputs: objectPath (required), propertyName (required).
Lists assets in a Content Browser directory. Use '/Game' for project assets, '/Engine' for engine assets.
Inputs: directoryPath (required), recursive.
Creates and opens a new empty level at the given asset path.
Inputs: assetPath (required).
Pilots an actor in the active editor viewport. Useful for seeing through a CameraActor.
Inputs: actorPath (required).
Checks whether the UE5 editor is reachable via the Web Remote Control API. Call this first to verify the connection before attempting other operations.
Inputs: no named parameters.
Renames an asset in the Content Browser.
Inputs: sourceAssetPath (required), destinationAssetPath (required).
Saves a specific asset.
Inputs: assetPath (required).
Saves the currently open level.
Inputs: no named parameters.
Applies a material to a StaticMeshComponent on an actor. The component is accessed as '.StaticMeshComponent0'.
Inputs: actorPath (required), materialPath (required), elementIndex.
Sets the value of a UPROPERTY on a UObject. Supports undo (Ctrl+Z). NOTE: Component properties (e.g., RootComponent, LightComponent) are often unavailable remotely. Use ue5_call_function with setter functions like SetActorScale3D instead.
Inputs: objectPath (required), propertyName (required), value (required).
Spawns an actor in the level from a static mesh asset or an actor class. Use objectPath for static meshes (e.g., '/Engine/BasicShapes/Cube.Cube') or actorClass for native classes (e.g., '/Script/Engine.DirectionalLight').
Inputs: objectPath, actorClass, location, rotation.
Spawns multiple actors in sequence. Useful for generating forests or large scenes quickly.
Inputs: transforms (required), objectPath, actorClass.

Scored across 20 tools
Most tools have clearly distinct purposes. There is slight overlap between get_property/set_property and call_function for property access, but descriptions clarify when to use each.
All tools use a consistent 'ue5_' prefix and mostly follow verb_noun snake_case. Minor deviations include 'new_level' (adjective+noun) and 'ping' (verb only).
With 20 tools, the scope is well-calibrated for Unreal Engine editor automation, covering asset management, level operations, actor manipulation, and debugging without being excessive.
The tool set covers core CRUD operations for assets and actors, level management, and property access. Minor gaps exist, such as limited support for component properties and no explicit undo tool, but these are workable.
