Grok Bot
Grok Bot reaches Reduck as a custom connector. There is no form to fill in: you ask the Bot in chat, and it adds the server itself.
Before you start
You need a Reduck account, and a paired browser if you want scripts to run on your own Chrome. Both are in the quick start.
Add the connector
Open a chat with your Bot and send this message:
Add a custom MCP server called Reduck at https://mcp.reduck.ai
Grok Bot adds Reduck and shows a Reduck card in the chat.

Connect your Reduck account
Click Connect on the card. Grok Bot opens Connect to Reduck. Click Continue.

A Reduck page opens in your browser and asks whether Cursor may connect to your account. Grok Bot connects through Cursor, so the page names Cursor and not Grok Bot. Sign in if it asks you to, then click Authorize.
Confirm it is connected
The card shows Connected · 1 Account, and Grok Bot tells you that the Reduck tools are ready.

To find it later, open Connect apps in the sidebar and click the connected count at the top right. Reduck is listed under Installed.
Try it
Ask for something on a real site, and let the agent pick the script:
Reduck finds a script for the site, runs it, and hands back the result. The script catalogue lists everything it can already do.
