Connecting to Sigma MCP Server: Overview

Metric Insights can connect to Sigma’s AI tools through a Model Context Protocol (MCP) Server, creating a secure, programmatic link from the Concierge service. With this integration, Sigma Conversational Analytics and related AI services become available directly in Concierge, so users can ask natural-language questions about Sigma data assets without leaving the platform.

Architectural Diagram for Sigma MCP Server Integration with Concierge

This diagram shows an example, where Sigma was configured to have Logistics Data and Support Data as Agents. Your Sigma can have other Agents set up with different names. These Agents correlate to their respective Domains in Metric Insights Concierge. A User can ask a question about logistics and Concierge will know to route that question through the Sigma Managed MCP Server to the specific Domain.

Steps to Connect Concierge and Sigma

  1. Decide on the Authentication method: Define how Concierge will perform authentication when connecting to Sigma:
    • "User OAuth": The Token is requested form Databricks and inserted into the configuration code automatically. The User only provides credentials to the service account in Sigma.
    • "Defined in configuration": The authentication Token has to be created in Sigma account and manually inserted into the Concierge configuration code. This Auth Type should be used if Sigma has the security model which doesn't include OAuth or there are other specifics that need a flexible solution. Be aware, that when the Token expires, it has to be re-entered into the configuration code manually.
  2. Configure Sigma and gather information for authentication: set the account type, find and copy the connection information.
  3. Configure External Resource in Metric Insights account: Set up Concierge to connect with Sigma.
