Narration: preview voiceA SaaS ops lead loads 500 trial signups from Claude. The rows and numbers are example data.

The short answer

Through Duckrow MCP your assistant can read your tables, campaigns and inbox, create workbooks and tables, add up to 500 rows at a time, update cells and run columns. Before anything paid, Duckrow tells it the most the run can cost and waits for your yes. Launching campaigns, sending messages and Persona fit columns stay in Duckrow.

Step by step

  1. 1Readlist_workbooks and list_tables; describe_table and read_rows (up to 100 rows a call); list_campaigns for status and lead counts; read_inbox for up to 50 recent replies with their campaign.
  2. 2Buildcreate_workbook and create_table (columns from a header row), add_columns for plain columns, add_rows up to 500 a call, update_cells.
  3. 3Runrun_column runs Find work email or mobile, Phone type, Email provider, Jev, Find customers, Use AI, an API column or a push, on some rows or the whole table. get_run follows it: rows done, found, skipped and credits charged.
  4. 4Cost firstWhen a run or new rows would cost credits, Duckrow returns the most it can cost and runs only after your yes.
  5. 5What stays with youLaunching campaigns, sending emails, texts, LinkedIn messages and inbox replies, Persona fit columns, and setting up enrichment columns.

Try it in Duckrow

About five minutes, in your own workspace.

  1. Ask your assistant: How is my newest campaign doing?
  2. Ask it to add three test rows to a table without paid columns, then check them in Duckrow.
  3. Ask it to run a paid column on 5 rows and read the cost it shows before you say yes.

You're done when you've seen a read, a build and a cost-first run.

Check what stuck

Three quick questions. Nothing is saved.

  1. 1. You ask Claude to email every interested reply. What happens?

  2. 2. Your table runs Find work email on new rows. Claude adds 500 rows. What comes first?

  3. 3. A Viewer connects Claude. What can it do?

Transcript

0:00Thirteen tools, in plain words

Once Duckrow is connected, your assistant gets thirteen tools. Here's what they do, and what stays with you.

0:09Read

It can read. Your folders, workbooks and tables. A table's columns and rows, a hundred at a time. Each campaign's status and lead counts. And recent replies from the inbox, fifty at a time.

0:25Build

It can build. Create a workbook or a table, add plain columns, add rows, five hundred at a time, and update cells.

0:35Run, with the cost first

And it can run columns. Here, an ops lead adds five hundred trial signups. The table runs Find work email on new rows, so Duckrow returns the most it can cost first, and Claude asks. After a yes, the rows go in and the run starts, and Claude can follow it.

0:56What stays with you

Some jobs stay in Duckrow, where you see exactly what goes out. Launching a campaign. Sending any message or reply. Running Persona fit columns. And setting up enrichment columns.

1:11Safe by default

It works as you. It sees only what you can see. A Viewer's assistant can only read. Paid runs always wait for your yes. And there's a limit of sixty calls a minute, with every call logged.

1:25Recap

To recap. It reads tables, campaigns and the inbox, and builds tables and rows. Paid runs show the cost and wait for your yes. Launching and sending stay in Duckrow. Next, the email rules in the US and Canada.
