Connects to MatterCatalog's read of the CSA Matter certification ledger and its product catalog. Muse can check whether a smart home device is Matter certified, list devices by category, platform or network, compare two products side by side, and name the US stores that sell them.

Example request: "Is the Aqara U200 Matter certified, and which US stores carry it?"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use MatterCatalog to help me. It is a free service with an MCP server at https://mattercatalog.com/api/mcp?src=mcp-registry. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.
