Use the Sigma plugin for ChatGPT
The Sigma plugin allows you to use natural language to interact with your Sigma organization from ChatGPT and Codex. The plugin connects you to the same tools available in the Sigma MCP server, so you can search for data sources in your organization, explore and describe their contents, and analyze your data without leaving ChatGPT or Codex. In addition, the plugin bundles a set of skills maintained by Sigma, along with the ability to build workbooks.
Use the Sigma plugin when you want easy access to your Sigma data from ChatGPT as well as the ability to build Sigma workbooks so you can save and share your analysis later. To install a read-only connector without the ability to build workbooks, follow the steps to Set up the Sigma MCP server in ChatGPT.
Sigma publishes this plugin as open source under the Apache License Version 2.0. Review the plugin license notice before installing or using this Sigma plugin.

Authentication
The Sigma plugin authenticates to Sigma using OAuth. You don’t need to configure anything beyond logging in to your Sigma account when prompted. The plugin inherits the permissions of your existing Sigma account.
Features
The Sigma plugin supports the following features for interacting with Sigma from an AI assistant:
Search, explore, and analyze your data
With the Sigma plugin, the assistant can locate a data source, compose a query, and return results to you in the chat interface.
To perform these tasks, the Sigma plugin uses a connection to the Sigma MCP server, established when you install the plugin and authenticate to your Sigma organization. The plugin uses the same permissions as your Sigma account, so you can only access data sources and documents that you have permission to view.
For explanations, example prompts, and use cases, see the Features and Usage examples sections of Use the Sigma MCP Server.
Build workbooks
Describe the workbook you want, and the plugin creates it in your Sigma organization. The assistant locates a data source, creates a workbook, and returns a link to the new workbook so you can review and continue building in Sigma.
Example prompts include:
- “Build a Sigma workbook that tracks monthly sales by region from the Sales data model.”
- “In Sigma, create a workbook with a bar chart of the top 10 customers by revenue.”
- “Add a page to the Regional Sales workbook in Sigma with a KPI for year-over-year growth.”
Using the plugin, you can create new workbooks and edit existing workbooks that you have access to. Created workbooks are saved in the Your documents folder in Sigma.
