Microsoft Sentinel MCP server: ask questions, get governed answers
Microsoft Sentinel is a cloud SIEM that holds security alerts, incidents, log data and analytics rule results.
Try it on your own data in a pilot.
Microsoft Sentinel AI analytics: what you can ask
Typical questions from security operations. Each answer shows the definition, source and query behind it.
- How many incidents were opened per week this quarter?
- Which analytics rules generate the most alerts?
- Show incidents by severity and status.
- Compare mean time to close incidents by month.
- List high-severity incidents that are still open.
How Nexatron connects to Microsoft Sentinel
- Whose permissions
- Your administrator approves the access the Microsoft Sentinel connection uses. Where Microsoft Sentinel 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 Microsoft Sentinel data.
- Setup
- Our team sets up the Microsoft Sentinel connection with your administrator during the pilot. No data migration and no pipeline to build: data is queried where it lives.

Try Nexatron on your own Microsoft Sentinel data
A pilot starts with three questions your team already asks and the report you trust for each, so you can check the answers yourself.
