What is the Scribble MCP server URL?

https://scribblecards.com/api/mcp — paste it into your assistant's custom connector setting and sign in to Scribble when prompted.

Which AI assistants can send handwritten cards with Scribble?

Claude, Claude Code, ChatGPT, Gemini Enterprise, the Gemini CLI, Microsoft Copilot Studio, Cursor, Windsurf and Zed — anything that supports Streamable HTTP MCP connectors.

Can an AI assistant send a card without my approval?

No. Sending is marked as an irreversible action, so a compliant assistant must show you the recipient and the message and get your confirmation first. You can also connect without the send permission at all.

Does Scribble see my AI conversation?

No. Scribble receives only the arguments of the tool the assistant calls — a name and address, the message to write, a card code. The protocol provides no way for a server to request the conversation.

MCP server

Your assistant can now put pen to paper.

Connect Scribble to Claude, ChatGPT or Gemini and ask for a handwritten card the way you would ask a colleague. A machine holds a real pen, writes it, and we post it — anywhere in the US, from $2.45 including postage.

What it can do, and what it can’t.

Giving an AI the ability to post physical mail is a real decision. Here is exactly where the edges are.

It can

Look someone up in your address book and read back their address
Draft a card and show it to you before anything is written
Check an address, a message length and your balance without spending a credit
Post a real handwritten card, after you confirm it
Tell you where a card has got to, step by step
Cancel a card that has not reached a machine yet, and give the credit back

It cannot

Send anything without asking you first — sending is flagged irreversible
Spend more than the credits you have already bought
See your API keys, your invoices or your payment details
Register a webhook, or point your data anywhere new
Read another organization's anything

A minute to set up.

1Paste the URL

Add a custom connector in your assistant and give it the Scribble server URL.

2Sign in to Scribble

A browser window opens. Sign in the way you normally do — the assistant never sees your credentials.

3Choose what it may do

Four tick boxes. Leave the send permission off if you only want help drafting.

4Ask for a card

That's it. Cards sent this way appear in your Scribble orders like any other.

Try it with one card.

Create an account, buy a single credit, and ask your assistant to send it. If a real card in real ink does not turn up on someone’s doormat, you have lost seven dollars.
