Elgato adds MCP support to Stream Deck: AI can now press your buttons

Elgato has released Stream Deck 7.4, an update that adds support for the Model Context Protocol (MCP). AI assistants such as Claude, ChatGPT and Nvidia G-Assist can now find and run actions on the device on the user's behalf.

What MCP support does

MCP support lets AI assistants discover Stream Deck actions that have already been configured and run them in response to a text or voice request from the user. The company stresses that the process of setting up buttons in the Stream Deck app does not change. The protocol only adds another way to activate them and does not replace familiar manual input.

• The update is called Stream Deck 7.4
• Supported AI assistants: Claude, ChatGPT and Nvidia G-Assist
• A separate guide to setting up the MCP connection is published on Elgato's official website
• MCP (Model Context Protocol) is a protocol used to connect AI models to external tools and devices

How Elgato describes it

Elgato explained how the new feature works in its official announcement of the update.

"You still configure actions in the Stream Deck app the way you always have.

MCP adds a new way to trigger them," Elgato said in its official statement.

According to the same statement, once connected, the user can type or speak a request, and the connected AI tool will find and run the right Stream Deck action itself. Elgato also notes that step-by-step setup instructions are on the support page of its website, and that anyone who wants to enable MCP will not have to change their existing button profiles.

Elgato's wording is aimed squarely at users who worry that the update will force them to reconfigure all their Stream Deck profiles. The company stresses twice in the announcement that the usual way of configuring actions stays unchanged, and that MCP is added only as one more way to trigger them.

What this means

Stream Deck now goes beyond physical button presses: it becomes a tool that can be controlled by voice or text through any AI assistant that supports MCP. This places Stream Deck in a growing ecosystem of applications that connect to AI tools through the open Model Context Protocol. Elgato presents MCP not as a replacement for familiar controls but as an additional layer on top of actions already configured, so users lose nothing if they decide not to connect an AI assistant at all.
