Is There an MCP Server for Microsoft Defender Data?

Before looking for a dedicated MCP server, check whether the data you need is already available through Defender’s APIs, command-line tools, or the connected SIEM. An API-based integration may be easier to secure and maintain than adding another service.

CyberDrain CIPP may be worth investigating. It can access much of this type of data and offers MCP support, along with a range of useful administration features. It’s especially practical if you manage multiple tenants.

I’d be cautious about giving an AI broad administrative access to security data. Start with read-only permissions, limit it to specific tenants and data types, and keep the normal admin console or approved APIs as the source of truth.

If you’re comfortable allowing an AI system to access the environment, a custom MCP server could be the most flexible approach. Microsoft’s APIs can be used to expose only the Defender data and actions you actually need, with tighter control over permissions and scope.
