PostAgent mcp_server
**PostAgent lets an AI agent send real, physical mail.** Upload a document, lock a price quote, pay per send, and PostAgent prints it and ships it via USPS. Built for autonomous agents: **pay per call in USDC on Base via the [x402](https://www.x402.org/) protocol** or credit cards, no signup, no human-issued API key, no billing account. ### What it does - **Letters** — PDF, HTML, Markdown, text, DOCX, or image; black & white or color. Optional **certified, certified-with-return-receipt, or registered** mail for proof of delivery. - **Postcards** — 4×6, 6×9, 6×11, full color from front/back artwork (4×6 can ship internationally). - **Address verification** — standalone US/international deliverability check (~2¢ per call). - **Mail merge** — personalize one template across many recipients with `{{fields}}`. - **Bulk campaigns** — one creative to up to 500 recipients (KYC-gated). Quotes are free and verify both sender and recipient addresses; the server always quotes first and only mails after explicit confirmation. **Sends spend real money and are irreversible once submitted.** US recipients · pay-as-you-go · no subscription.
