How to integrate Smartsheet using MCP
Read and update Smartsheet sheets, columns, reports, and users. This guide creates an MCP server from Arthur's Smartsheet template — tools preconfigured against https://api.smartsheet.com/2.0 — and finishes by sharing the server's MCP swagger documentation.
Steps
Open the Secrets vault and create a secret named
SMARTSHEET_API_KEYholding your access token. Generate a personal API access token from your Smartsheet account (Personal Settings > API Access) and send it as Authorization: Bearer. OAuth2 access tokens obtained via the full authorization flow work the same way. 


Go to the REST API Templates gallery and search for Smartsheet.


Click Use template on the Smartsheet card to open the server-creation dialog.


Review the server name and select
SMARTSHEET_API_KEYin the credential field — the dialog only accepts vault secrets, and it lists every tool that will be created.


Click Create server. Arthur creates the server, applies the authentication, and generates all the tools.





Open the server's Tools tab to review the generated tools.

Open the server's Connect section and click Share the MCP swagger documentation — Arthur generates the public documentation link and QR code for this server.



Confirm it worked
The server appears with 5 preconfigured tool(s): list_sheets, get_sheet, add_column, list_reports, list_users. The Connect section offers the MCP swagger documentation — a shareable page with setup instructions for any AI client.
Good to know
- List and retrieve Smartsheet sheets and reports, add columns to a sheet, and list account users. Requires a Smartsheet personal API access token (Business or Enterprise plan) or an OAuth2 access token.
- This integration requires a credential (bearer). Get one at https://app.smartsheet.com/b/signup.
- Official API documentation: https://developers.smartsheet.com/api/smartsheet/openapi/
- Editing a tool later never changes the template — templates are starting points, and the server is fully yours after creation.
