Product Duckrow MCP
Duckrow MCP: run your outbound from Claude or ChatGPT.
Duckrow MCP connects the AI assistant you already use to your Duckrow workspace. Ask it to turn a spreadsheet into a table, find the emails that are missing or tell you what came in overnight. It signs in as you and shows the cost before it spends a credit.
CursorPaste it into your assistant as a custom connector, then sign in to Duckrow. Cursor and Gemini set up the same way.
In my “EU heads of growth” table, who still has no work email? Fill those in.
38 of 120 rows have no work email. Finding them runs your Work email column on those 38 rows, charged only when an email is found. Shall I go ahead?
Yes, go.
What is Duckrow MCP?
MCP, the Model Context Protocol, is the open standard AI assistants use to work with other apps. Duckrow MCP is Duckrow's own MCP server. Add its address to Claude, ChatGPT, Cursor or Gemini, sign in once, and your assistant can read your tables, campaigns and inbox, build tables, run columns, and launch leads or answer replies once you say yes, with your permissions.
- One address
- The same https://duckrow.ai/mcp goes into Claude, ChatGPT, Cursor and Gemini.
- Your own sign-in
- You sign in with your Duckrow account and press Allow. There is no API key to copy or keep safe.
- Every plan
- Duckrow MCP comes with every Duckrow plan, Free included. Paid columns use the same credits as in the app.

What stays with you
Before your assistant launches leads or sends a reply, it shows you exactly what goes out and waits for your yes.
- Creating a campaign, or changing its steps and senders.
- Starting a new conversation outside a campaign.
- Running Persona fit columns.
- Setting up API, Jev, Use AI and LinkedIn data columns. You set those up in Duckrow.
It works with your permissions and asks before it spends.
Duckrow MCP runs every call as you, through the same rules as the Duckrow app.
Signs in as you
OAuth sign-in with your Duckrow account. You press Allow on Duckrow's own screen.
Sees only what you can see
Your assistant gets your access and your role, and nothing more.
One workspace at a time
Your assistant works in the workspace you last picked in Duckrow. It uses another of your workspaces only when you name it.
Viewers stay read only
A Viewer's assistant can read tables, campaigns and the inbox, and can't change or spend anything.
Cost first, every time
Before a paid run, Duckrow tells your assistant the most it can cost and waits for your yes. Adding rows that would set off paid columns asks first too.
Your yes before anything goes out
Launching leads or sending a reply shows you the lead count or the exact message first. Nothing goes out until you agree, and the inbox's own rules apply, opt-outs included.
A speed limit
Up to 60 calls a minute for each person, so a runaway chat can't flood your workspace.
Every call logged
Duckrow records who called which tool and whether it worked.
Prompts to try.
Copy one into your assistant once Duckrow MCP is connected.
Make a Duckrow workbook called Q4 agencies from this spreadsheet.
Which rows in my EU heads of growth table have no work email? Find them, and tell me the cost first.
Run the Jev column on the first 50 rows of my clinics table and tell me how many said yes.
How is my Agencies Q4 campaign doing?

Draft an answer to the newest interested reply and show it to me before you send it.
