Smartsheet’s MCP server lets agents read and update sheets, search workspaces, manage folders, and create discussions. It uses personal access tokens, so each user should supply their own token through TrueFoundry Auth Overrides.

​
Prerequisites

  • A TrueFoundry account with permission to add MCP servers.
  • A Smartsheet Business or Enterprise plan with API access.

​
Register in TrueFoundry

Open MCP Gateway, click Add MCP Server, select Connect any Remote MCP Server, and configure:
FieldValue
Namesmartsheet
URLhttps://mcp.smartsheet.com
AuthenticationAPI Key
Credential modeIndividual Credentials
Header nameAuthorization
Header valueBearer {{API_KEY}}
Add collaborators and save the server. Users must add their token in the Auth Overrides tab before using the server.

​
Generate a Smartsheet Token

Each user opens Smartsheet, goes to Personal Settings > API Access, clicks Generate new access token, names it, and copies the token immediately. Paste only the token value into the TrueFoundry auth override.

​
Security Notes

Smartsheet personal access tokens inherit the generating user’s full permissions and do not provide granular scopes. Review write tools such as row updates before exposing them broadly, and use Virtual MCP Server to publish only the safest tools.
