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.
Hey Product Hunt. We built PieterPost MCP because agents can write a message, but usually stop before the physical part: addresses, files, checkout, printing, and mailing.
This launch adds a remote MCP server at pieterpost.com/mcp. Agents can quote a letter or postcard, create a checkout link, use Mailbook contacts, upload assets, and track the order. For normal one-off sends, payment happens before anything is mailed. For trusted integrations, the API and direct-send path is still there.
MCP is one feature of PieterPost, not a separate company. PieterPost already helps people send letters and postcards online. This makes that postal layer available from agent workflows.
Curious what you would trust an agent to send by mail first.
