Stream Deck gets AI hooks
Elgato’s Stream Deck 7.4 adds Model Context Protocol (MCP) support so AI assistants — Claude, ChatGPT, Nvidia G‑Assist — can discover and trigger Stream Deck actions automatically. The feature ships as a Node.js tool + a new MCP Server bridge, meaning you can script your bot to switch OBS scenes, fire macros, or trigger VST chains on command.

Elgato published Stream Deck 7.4 on April 1, 2026 and lists macOS and Windows installers in the official release notes. (help.elgato.com) The app exposes a new profile you create by opening Preferences → General and checking “Enable MCP Actions”; any keys placed into that MCP Actions profile become visible to external MCP-capable services while actions on other profiles remain private. (elgato.com) Elgato’s setup requires installing a local Elgato MCP Server that runs on a Node.js runtime, and the vendor’s guide calls out that Claude Desktop and NVIDIA G‑Assist setup flows expect that bridge to be available. (elgato.com) Every MCP Actions key includes an AI description field (the AI icon appears in the action settings) and Elgato instructs users to write both what an action does and the kinds of prompts that should trigger it — for example, “This mutes the system audio.” (elgato.com) The 7.4 release notes also introduce a new hardware entry called Stream Deck + Lever and point users to explicit download links for the 7.4 installers on Elgato’s site. (help.elgato.com) Community MCP server projects and third‑party implementations (examples on GitHub and PyPI) are already circulating; several require Node.js 20+, can write directly to the Stream Deck app’s native profile files, and some warn that the official Stream Deck software must be quit due to exclusive USB access.
