Full read-write Claude connector for Smartsheet
Make Claude add rows and keep trackers current in Smartsheet
Stop clicking through the grid to log updates by hand. Claude adds rows, updates status and dates, sets assignees, and posts comments right in Smartsheet, with deletes gated behind your approval.
Smartsheet is a spreadsheet-style work management platform where teams run projects, trackers, and reports across grids, Gantt views, and dashboards. People want Claude to do more than read a sheet: to add and update rows, move work forward, and keep trackers current on their behalf.
What is a Smartsheet MCP server?
A Smartsheet MCP server is a small hosted service that exposes Smartsheet's data and actions to Claude over the Model Context Protocol, so Claude can tasks, projects, and docs inside your own account. We build it as a custom connector with separate read and write tools, and destructive actions stay gated behind your approval.
What can Smartsheet's current connector do today?
Today, Smartsheet's available Claude connections lean toward reading and search: Claude can look up sheets and rows, but adding rows, updating cells, posting comments, and changing assignments are often limited or cover only a thin slice. A custom Smartsheet connector adds those write actions with scoped, human-in-the-loop controls.
What does full read-write Smartsheet access unlock?
Full read-write Smartsheet access lets Claude add rows to the right sheet, update cell values and status columns, set assignees and due dates, attach comments, and move work along. The tracker upkeep that used to mean clicking through the grid happens where the work already lives, once you approve.
- Add a new row to a chosen sheet with values, an assignee, and a due date
- Update cell values like status, priority, or percent complete from a discussion
- Set or change the assigned contact and dates on existing rows
- Post a comment or update on a row to capture context
- Move a row's status forward as the work progresses
- Find every row matching a query and propose batched updates
Can Claude add and update rows in Smartsheet?
Yes. With a full read-write Smartsheet connector, Claude can add a new row to a chosen sheet with values, an assignee, and a due date, then update cell values like status, priority, or percent complete on existing rows. Adding and updating rows flow freely once the connector is in place.
Can Claude set assignees and post comments on Smartsheet rows?
Claude can set or change the assigned contact and dates on existing rows and post a comment to capture context as work moves forward. It can also find every row matching a query and propose batched updates, so tracker upkeep happens where the work already lives rather than by hand.
Will Claude delete Smartsheet rows or get more access than I have?
No. Destructive actions like deleting a row are gated and require your confirmation before they run. The connector authenticates as your account through OAuth and inherits your existing permissions, so it only ever touches the sheets and rows you already have access to yourself.
How a Smartsheet connector works
We build a small MCP server that authenticates to Smartsheet with OAuth and the narrowest scopes the work needs. Read tools (search, look up sheets and rows) and write tools (add row, update cells, comment) are separated, and destructive actions like deleting a row require your confirmation. Claude only ever has the access your own Smartsheet account already has.
