Microsoft released Azure MCP Server 3.0 on October 12, 2026. It adds tools for Azure Backup, Resilience Management, and SRE Agent workflows. New Terraform and Advisor tools help turn recommendations into infrastructure changes. Azure Monitor, Cosmos DB, IoT Hub, and Insights tools expand data and device capabilities. Tool contracts and security defaults are now clearer and stronger. Structured responses and new metadata improve client integration. Upgrades require refreshing discovery, response parsing, and configuration. Security defaults now disable less secure options for new resources. The server supports multiple editors, desktop apps, and CLI agents. Shared deployments need testing before upgrade.
