Send paper mail from Claude in two minutes.

Add the PaperAgent connector once. After that, sending a letter is just asking.

Works on every Claude plan. On Team and Enterprise an owner adds it once in organisation settings and everyone else connects from their own Connectors page.

— you’ll paste this in step 2
  1. 01ADD

    Add a custom connector

    In any chat, open the + menu and choose Add connector, then Add custom connector.

    The plus menu in a Claude chat, open at Add connector, with Add custom connector highlighted
    + menu → Add connector → Add custom connector.
  2. 02CONNECT

    Paste the PaperAgent address

    Name it PaperAgent, paste in the URL field, and click Continue. Claude finds the tools on its own; there is nothing else to configure.

    The Add custom connector dialog, filled in with the name PaperAgent and the MCP address
    The Add custom connector dialog — the address goes in the URL field.
  3. 03CONFIRM

    Leave authentication on None

    Claude has already detected that PaperAgent needs no sign-in up front. Leave None selected and click Add.

    The authentication step, with None selected and marked Detected, above the Add button
    None is already selected and marked Detected — just click Add.
  4. 04RELOAD

    Reload the page

    The new connector does not appear until you reload. Then open the + menu again and, under Connectors, switch PaperAgent on.

    The Connectors menu in a chat, with the PaperAgent toggle switched on
    After reloading: + menu → Connectors → PaperAgent on.
  5. 05INVOKE

    Just ask, then allow the tool

    Ask in plain language, or attach a PDF and ask Claude to mail it. The first time Claude drafts a letter it signs you in by email, then asks permission to use the tool — choose Always allow and it stops asking for that tool.

    • Mail this cancellation letter to my gym.
    • Send my landlord a certified letter about the deposit.
    • Where is my letter now?
    A chat with a PDF attached, asking Claude to send it as a paper letter
    Attach a PDF, or describe the letter and Claude writes it.

That’s it — the tool will handle the rest.

One connector, no app to install, and your first letter goes out within one business day.
