Premier Letters connects to a handwriting and mailing service. Muse can help you quote, preview, order and track real pen-written letters and postcards sent via USPS, with options for handwriting style, paper type and delivery method.

Example request: "Send a handwritten thank-you letter to my client and track when it arrives."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Premier Letters to help me. It is a free service with an MCP server at https://www.premierletters.com/api/mcp. 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.
