Common questions

Is PieterPost MCP safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.2.0) reached the registry 6 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

PieterPost MCP

PieterPost MCP is a hosted Model Context Protocol (MCP) server for preparing, pricing, reviewing, paying for, and sending real physical letters, postcards, designed letters, and printed greeting cards from ChatGPT, Claude, and other compatible AI assistants.

This public repository contains the integration documentation and registry metadata for the hosted PieterPost MCP server.

Server

MCP server URL: pieterpost.com/mcp/setup/
Human docs: PieterPost MCP documentation
Markdown docs: PieterPost MCP documentation in Markdown
OAuth issuer: https://pieterpost.com/mcp/oauth

What It Does

PieterPost gives MCP clients a safe postal outbox. Agents can design letters and printed greeting cards with PNG previews, draft letters and postcards, quote prices, create review links, create hosted payment links, upload assets, use Address Book 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.

For greeting cards, use list_card_options, create_card_design, get_card_design, and update_card_design. Upload a supplied photo with upload_asset, then use its asset ID in the design. The private editor link lets the user refine and order the card. Card drafts do not create a paid order. Explain fallback-font and print warnings before ordering.

For designed letters (fonts, colours, photos, illustrations, extra pages, personal fields like {{first_name}}), use list_letter_options, create_letter_design, get_letter_design, and update_letter_design. Pick the postal layout for the recipient's country. Results list print issues per page, including clashes with other countries' address windows; these block ordering. The private editor link lets the user add recipients and order the letter.

The guest server at https://pieterpost.com/mcp/public/ needs no account or authentication. It includes the four card tools, the four letter design tools, and nine public mail tools. Account tools and saved contacts use the OAuth server above.

Client Configuration

Use this server URL in MCP clients that support remote Streamable HTTP servers:

https://pieterpost.com/mcp/setup/

Example MCP client snippet:

"type": "mcp", "name": "PieterPost", "server_url": "https://pieterpost.com/mcp/setup/" }

Cursor and Grok Bot plugin

This repository also contains a Cursor plugin manifest at .cursor-plugin/plugin.json. The plugin connects to the public Streamable HTTP server at https://pieterpost.com/mcp/public/. It provides 17 tools and needs no account, API key, or sign-in. Users review and pay on PieterPost before printing and posting.

For review, connect to the public server and test the tools with synthetic data. Use mode=test for mail operations and a fresh UUID idempotency key for each new operation. Check the result before retrying an operation. Do not pay or submit a live order during testing.
