Overview

AI-generated overview

Lets an assistant draft and order real printed postcards and letters mailed via USPS, with payment and human review before printing.

What it does
Sendpaper exposes tools to get pricing, create a postcard or letter, pay for an order, check an order, and cancel an order. The agent drafts the mail and receives a print preview plus a Stripe checkout link. Nothing is printed or mailed until the order is paid, and a person reviews each piece before it goes out via USPS First-Class to US addresses.
When to use it
Use it when you want an assistant to turn a message into physical mail sent to a US address, such as a thank-you note, announcement, or outreach piece. It suits workflows where you are willing to review a preview and pay per item.
Requirements
A remote MCP endpoint at over streamable HTTP; no local package or runtime is needed. Payment is handled through Stripe, including a Stripe shared payment token approved via Stripe Link. Mailing is limited to US addresses.
Before you install
Orders cost money: postcards are $2.99 or $3.99 and letters $4.99, and an agent can pay with a Stripe shared payment token you approve. Creating and paying for an order causes real mail to be printed and sent, so review the preview and confirm the recipient address before approving payment. Orders can be cancelled with the cancel_order tool.
