Overview

AI-generated overview

Postly lets an assistant send physical letters to Danish addresses, check prices and balance, and track letter and order status.

What you can do
  • Look up current prices for regular and registered letters
  • Create a letter order and get a payment link the user opens and pays themselves
  • Send a physical letter charged to a prepaid balance, using an API key
  • Check the status of a sent letter by its id and list recent letters on the account
  • Check the prepaid balance and account status, and track the status of a created order
When to use it
Useful when someone wants an assistant to post a real printed letter to a Danish address, either by paying per letter through a payment link or from a prepaid business account, and to follow up on delivery status.
Requirements
Remote streamable HTTP endpoint at postly.dk; no local install. An optional Authorization header with a Bearer Postly API key unlocks send_letter, get_letter_status, list_letters and get_balance; without a key only pricing, order creation and order status are available.
Before you install
Sending a letter costs money: with a key the amount is deducted from the prepaid balance and a sent letter cannot be cancelled; without a key the user must open a payment link and pay before the letter is sent. Always confirm the recipient address and price with the user first. The API key is passed in the Authorization header.

Installation

In SourceWeft

  1. Open Postly in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.gustavmakes%2Fpostly/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Add this to your client's mcpServers config.
