PieterPost MCP
Launching today
PieterPost MCP connects AI agents to postal mail. From ChatGPT, Claude, Codex, Claude Code, or any MCP client, agents can prepare letters and postcards, use Mailbook contacts, upload attachments or postcard images, create checkout links, and track orders. It brings PieterPost online mail, API, and payment-link workflows into agent tools.

Physical mail as an MCP tool is a fun edge because it's one of the few agent actions that's genuinely irreversible once it's in the postbox. What's the confirm boundary here: does a human have to click through the checkout link, or can an agent with a saved payment method quote-and-send in one shot? For a tool that spends money on a physical artifact I'd want the resolved address read back and a hard human gate, since a hallucinated recipient isn't a retry, it's a stranger opening my letter.
