Unreal Engine Absolute MCP

UEAMCP is a Model Context Protocol server that lives inside the Unreal Editor. Install the plugin, open your project and any MCP-capable AI agent can build Blueprints, configure input, manage assets and play-test your game, through a local HTTP endpoint.

• Local only. Nothing leaves your machine: no accounts, no API keys, no telemetry, no UI.
• Every engine from UE 4.27 to UE 5.8, one plugin, same tools.
• Transactional. Every change is an editor transaction: the agent (or you, with Ctrl+Z) can undo it.
• Streamable HTTP + SSE, protocol 2025-06-18, with progress notifications and cancellation.
