add_column
Create a new column on the specific Retable
LABSCO SUMMARY
A spreadsheet that builds itself out of the conversation.
Because the structure tools sit beside the row tools, a single request can go from I need somewhere to track this to a table with the right columns and its first rows already in it. Everything after that — reading, correcting, extending — happens in the same place.
What it is
The Retable MCP server. It reaches the whole hierarchy — workspaces, projects, tables, columns and rows — so an agent can create the structure and then put data into it.
What you get
- All your workspaces, one workspace with its projects, and new ones created or deleted
- Projects created under a workspace with a default table, opened, and deleted
- Tables listed in a project, created and read
- Columns added to a table and removed from it
- Rows read, inserted, updated and deleted
Requirements
A Retable account and a Retable API key, plus a recent Node.js. It runs with npx and the key goes in the client configuration as RETABLE_API_KEY.
Setup effort
One command plus a key — npx -y retable-mcp-server, then supply credentials
USE CASES
01
Setting up a tracker from scratch
Create the workspace, the project under it and the table inside that, then add the columns the data actually needs.
02
Getting data into a table you already have
Find the table in the project, read its shape, and insert the rows — the shape check is what stops a row landing in the wrong columns.
03
Answering a question from what a table holds
Read the rows and the table definition together, so the answer accounts for what each column means rather than just its values.
04
Fixing records that came in wrong
Read the rows, correct the ones that are wrong in place, and delete the ones that should never have been added.
05
Reshaping a table as the work changes
Add the column the new question needs and drop the one nobody fills in, then read the table back to confirm the shape.
06
Finding your way around an account you inherited
List every workspace, open the one that looks live, and read the projects inside it before touching anything.
