Handler vs ue-mcp

Handler: Handler is an open-source A2A protocol client for your terminal. It provides a TUI and CLI to send messages, manage tasks, and inspect agent cards. An included MCP server lets AI assistants communicate with A2A agents.; ue-mcp: UE-MCP (Unreal Engine Model Context Protocol Server) gives AI assistants deep read/write access to the Unreal Editor through 19 category tools covering 300+ actions. It uses a WebSocket JSON-RPC bridge plugin inside the editor and provides direct filesystem access. This enables programming Blueprints, materials, levels, actors, animation, VFX, landscape, PCG, foliage, audio, UI, physics, navigation, AI, GAS, networking, sequencer, and build pipeline through natural language.
