Elgato announced MCP support for Stream Deck, opening the platform up to AI assistants for the first time. With this integration, AI tools that support the Model Context Protocol (MCP) can now connect to Stream Deck and trigger actions selected by the user. NVIDIA Project G-Assist, the on-device AI assistant for GeForce RTX PCs, is the first to connect, giving gamers voice control over their entire setup. Aitum, a popular automation platform for streamers, is also integrating, letting live events like raids and subscriptions trigger Stream Deck actions. More partners are on the way.

"We've spent years bringing Stream Deck to more surfaces,” said Julian Fest, SVP and General Manager of Elgato. “We put it in a mouse, a keyboard, and on your screen. Opening it up to AI is the next step in that journey, and we're just getting started.”

How it Works
Users with the latest version of Stream Deck software can enable the integration in their settings. This creates a dedicated virtual device called MCP Deck, with 32 keys that can be filled with actions from Stream Deck's vast library of integrations. An MCP server connects AI tools to the deck, but the user decides exactly which actions to make available, keeping control predictable and intentional.

NVIDIA Project G-Assist
NVIDIA G-Assist is an on-device AI assistant for GeForce RTX PCs. Powered by a small but capable language model running locally on the GPU, it responds to voice and text commands, letting users optimize performance and manage their system on the fly.

With Stream Deck integration, G-Assist's reach expands well beyond the desktop. Through a dedicated plugin, it connects to the user's MCP Deck, gaining access to every action on it. It also brings something entirely new to Stream Deck: voice control. For the first time, users can trigger Stream Deck actions just by speaking. Here's what that looks like in practice. Gamers can trigger in-game abilities or save a clip by voice, keeping their hands on the keyboard and mouse. Streamers can launch their entire broadcast setup with a single spoken command. Video editors can fire off actions without reaching for a key or breaking their creative flow.

These are just a few examples. With Stream Deck's vast library of integrations and deep customization, there's plenty more to discover.

"Project G-Assist helps gamers and creators get more from their PCs. Stream Deck expands that even further, giving G-Assist access to a whole new range of actions beyond system settings," said Gerardo Delgado, Senior Director of Product Management at NVIDIA. "Press a button for a single action, or talk to G-Assist to trigger several at once. That's AI delivering real, everyday value."

Aitum
Aitum Nexus is a popular automation platform that helps creators run more interactive and responsive livestreams. It already connects to platforms such as Twitch and YouTube, as well as broadcast tools like OBS and Streamlabs Desktop. With MCP integration, its reach expands into Stream Deck's broader ecosystem, letting live events trigger actions across it. This opens up a new kind of reactive production. A donation could activate a voice effect. A channel point redemption could post a message in Discord. A raid could launch a Multi Action that switches scenes, dims the lights, and plays a sound all at once. The more a creator has built into Stream Deck, the more Aitum can do with it.

Looking Ahead
G-Assist and Aitum are the first to connect to Stream Deck through MCP, but they won't be the last. Because MCP is an open standard, any compatible AI platform can plug in the same way. Each one inherits Stream Deck’s ecosystem — the apps, hardware, shortcuts, and systems that users have already built into their workflows. AI provides the input; Stream Deck provides the actions.

Availability
Stream Deck's MCP support, a new plugin for NVIDIA Project G-Assist, and Aitum integration are available today. To get started, users need Stream Deck 7.4 or later and an existing Stream Deck device.

GeForce RTX owners can install G-Assist through the NVIDIA App, where the Stream Deck plugin comes pre-installed with v0.2.1. Setup also requires the Elgato MCP server, with a step-by-step guide available to help.
