Does Nexatron respect Sigma permissions?

Yes. Where Sigma supports per-user sign-in, answers run under each person's own access.

Can Nexatron change data in Sigma?

No. Asking a question never changes Sigma data.

What do I need to connect Sigma?

An administrator who can approve the connection. Our team sets it up with them during the pilot.

Yes: Nexatron's hosted MCP server, once Sigma is connected to your workspace. It is Nexatron's server, not one published by Sigma, and the assistant gets the same governed answer as the Nexatron app.

How Nexatron connects to Sigma

Whose permissions: Your administrator approves the access the Sigma connection uses. Where Sigma supports per-user sign-in, answers run under each person's own access, and Nexatron roles decide who in your company can ask.
Read and write: Questions are read-only: asking never changes Sigma data.
Setup: Our team sets up the Sigma connection with your administrator during the pilot. No data migration and no pipeline to build: data is queried where it lives.

Sigma MCP connector for Claude, ChatGPT and Copilot

Nexatron's hosted MCP server is a governed Sigma MCP connector: Claude, ChatGPT and Microsoft Copilot ask questions of your Sigma data through it. Each person signs in as themselves, so the assistant sees only what they may see.

Connect Sigma to Claude, ChatGPT or Copilot

Connect Sigma to your Nexatron workspace.
In Claude, add Nexatron from Claude's connector directory. In ChatGPT or Copilot, add a custom MCP connector with the server URL https://api.nexatron.io/api/v1/mcp.
Sign in with your own Nexatron identity (OAuth 2.1), then ask your Sigma questions.
