Cassandra MCP server: ask questions, get governed answers

Cassandra dashboard questions you can ask

Typical questions from engineering and platform. Each answer shows the definition, source and query behind it.

• How many events were written per day over the last 14 days?
• Which 10 partitions in the events table hold the most rows?
• Compare message volume this week with last week
• List devices that haven't reported any readings in the last 24 hours
• Break down records by type and region for last month

How Nexatron connects to Cassandra

Whose permissions

Your administrator approves the access the Cassandra connection uses. Where Cassandra 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 Cassandra data.

Setup

Our team sets up the Cassandra connection with your administrator during the pilot. No data migration and no pipeline to build: data is queried where it lives.

Cassandra MCP connector for Claude, ChatGPT and Copilot

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

Connect Cassandra to Claude, ChatGPT or Copilot

1. Connect Cassandra to your Nexatron workspace.
2. 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.
3. Sign in with your own Nexatron identity (OAuth 2.1), then ask your Cassandra questions.

Cassandra connector FAQ

Can I ask Cassandra questions without writing queries?

Yes. Ask in Teams, Slack, the Nexatron web app, or an AI assistant connected through Nexatron's MCP server.

Does Nexatron respect Cassandra permissions?

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

Can Nexatron change data in Cassandra?

No. Asking a question never changes Cassandra data.

What do I need to connect Cassandra?

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

Is there a Cassandra MCP server for Claude, ChatGPT or Copilot?

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