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.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
