MCP server enabling AI agents to send physical postal mail directly.

Overview

PieterPost MCP is a Model Context Protocol server that connects AI assistants like ChatGPT, Claude, and Codex directly to physical postal mail services. The platform enables AI agents to draft, format, and address letters or postcards, access saved contact books, and generate secure payment checkout links without leaving the chat interface. Built around a human-in-the-loop draft review model, PieterPost ensures that physical printing and mailing occur only after explicit user authorization and payment confirmation.

Founder story

PieterPost was created as an online physical mail API and extended to the Model Context Protocol ecosystem by indie developer Pieter Levels in 2026. Recognizing that AI agents could synthesize text and analyze documents but lacked the ability to execute physical real-world actions, Levels built the remote MCP server to bridge AI clients directly to global printing and postal fulfillment infrastructure.
