Add a custom connector
Choose Add custom connector at the bottom of the list.
Paste the Scribble server URL
Name it Scribble and use this URL:
Text https://scribblecards.com/api/mcpSign in and choose permissions
Claude opens a Scribble window. Sign in, untick anything you do not want the assistant to do, and confirm.
You’ll know it worked when The connector shows as connected and Scribble's tools are listed under it.
Turn it on in a conversation
In a new chat, open the tools menu and make sure Scribble is enabled, then ask it something.
#Claude Code
claude mcp add --transport http scribble https://scribblecards.com/api/mcpThen run /mcp inside Claude Code and choose Authenticate next to scribble. Your browser opens for the same sign-in and permission screen.
#Slash commands you get for free
The connector ships three prompts, which appear in Claude as commands:
- Write and send a card
- Asks who it is for and what for, drafts it, checks the address, and waits for your approval.
- Check on cards I have sent
- Lists what is in flight and where each one has got to.
- Plan a batch of thank-you cards
- Works through a list, drafts a genuinely different card for each, and shows you the whole batch and its cost before anything is sent.
#If it will not connect
| What you see | What it means |
|---|---|
| Could not connect to server | Check the URL has no trailing slash and ends in /api/mcp. scribblecards.com/mcp is the information page, not the server. |
| The sign-in window opens and closes without connecting | You are probably signed in to a Scribble account with no organization. Create one, then reconnect. |
| Custom connectors are not available | Your plan or your organization's settings do not allow them. An owner can enable custom connectors in the Claude admin settings. |
| Connected, but the tools do nothing | Open a new conversation. Claude picks up a connector's tools when a chat starts. |
