Sendpaper
Print and mail real postcards and letters to any US address.
Sendpaper prints and mails real postcards, letters and USPS Certified Mail with tracking to US addresses. Ask Muse to mail a thank-you or birthday postcard, a letter you write, your own PDF, or the same card to up to 25 people. Muse shows you the exact print preview and a Stripe checkout link; nothing is mailed until you pay. A person reviews every piece before it prints. Senders can be anywhere; recipients must be in the US. No account or sign-in needed.

How to add it to Muse
Not in Muse's Connectors list yet, but Muse can still use it. Copy the request below and paste it into Muse. 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.
https://sendmypaper.com/mcpSent to Meta for approval. Until then you can add it with a link.
Also use it in ChatGPT or Claude
Sendpaper is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
Add it to ChatGPT
- 1
Open ChatGPT settings
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
- 2
Turn on developer mode
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
- 3
Create the connector
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
- 4
Use it in a chat
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
