Unreal MCP

Unreal MCP lets AI assistant clients (Claude Desktop, Cursor, Windsurf) control Unreal Engine 5 through natural language via MCP, enabling actor creation, Blueprint scripting, viewport control, and level design automation through a C++ TCP plugin and Python MCP server bridge.

Best When

You are a UE5 developer who wants to use Claude Desktop or Cursor to accelerate level design and Blueprint creation through conversational AI, and you are comfortable with experimental tooling.

Avoid When

You need production-stable tooling or are on UE5 versions older than 5.5.

Use Cases

  • Using Claude or Cursor to create and position actors in a UE5 level through conversational commands
  • Automating Blueprint class creation, node graph wiring, and variable setup from natural language descriptions
  • Controlling the UE5 editor viewport and camera focus programmatically from an AI agent

Not For

  • Unity developers (Unreal Engine 5 only)
  • Production pipelines requiring stable, non-breaking APIs (project is explicitly Experimental)
  • Teams needing runtime in-game AI integration (editor-only tool)

Known Gotchas

  • Explicitly marked Experimental — breaking changes expected
  • Requires UE 5.5 or later
  • Three-component architecture (C++ plugin + Python server + sample project) adds setup complexity
  • TCP server on fixed port 55557 — port conflicts possible
  • Python 3.12+ required
