Example request: "What's the sales tax rate for an order shipping to 123 Main Street, Portland, Oregon?"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Ziptax Sales Tax API to help me. It is a free service with an MCP server at https://mcp.zip-tax.com/. It needs an API key from ZipTax; ask me to enter it through your secure credential prompt. 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.
