Connects Muse to InvoiceThem so freelancers and contractors can create invoices, send them to clients and check which ones are paid or overdue, without opening the app.

Example request: "Send my latest invoice to Acme and tell me which clients still owe me money."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use InvoiceThem to help me. It is a free service with an MCP server at https://api.invoicethem.io/mcp. It needs an API key from InvoiceThem; 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.
