PieterPost MCP

What It Does

PieterPost gives MCP clients a safe postal outbox. Agents can draft letters and postcards, quote prices, create review links, create hosted payment links, upload assets, use Mailbook contacts, and check order status.

For normal use, agents should create a PieterPost review or payment link. PieterPost sends the mail only after the user reviews and pays.
