Elgato Stream Deck 7.4 Adds MCP Support — AI Agents Can Now Control Physical Hardware Buttons

The Verge·medium signal

Elgato's Stream Deck 7.4 update adds Model Context Protocol (MCP) support, allowing AI agents to programmatically trigger Stream Deck buttons and control connected hardware, software, and automations. This is the first consumer hardware product to ship native MCP agent integration, turning the Stream Deck into a physical actuator layer for AI workflows. For builders running agent pipelines, this means agents can now trigger OBS scenes, smart home devices, and macOS shortcuts through physical hardware.
