Build AI Agents and RAG Applications with the New LangChain + LangGraph Connector for Azure Cosmos DB Building AI agents and RAG applications today means stitching together half a dozen services, a vector database, a chat history store, a checkpointer for agent state, a semantic cache, a long-term memory layer. Each adds operational overhead, late...

Introduction Managing access to Azure resources often means dealing with two separate permission models: one for management operations and another for data access. For Azure Cosmos DB customers, this split can increase complexity, slow down onboarding, and create confusion around governance and security boundaries. Today, we’re excited to annou...

We’re excited to announce the general availability of private network support for Azure Cosmos DB mirroring in Microsoft Fabric, enabling customers to replicate operational data into Fabric from Azure Cosmos DB accounts secured with private endpoints or virtual networks while continuing to operate within their existing network security models. As m...

In the first post of this series, we introduced how Azure Advisor helps Azure Cosmos DB users uncover opportunities to optimize efficiency and make smarter decisions. This follow-up dives deeper into one of the most important categories of guidance: performance. If you've ever dealt with skewed workloads, unexpected RU consumption, or queries th...

Strengthen Identity Security and Eliminate Account Keys Identity is becoming the new security perimeter. As organizations modernize their cloud applications, long‑lived secrets and shared keys introduce unnecessary risk. Azure Cosmos DB now fully supports Microsoft Entra ID for both control plane and data plane access, giving customers a secure, p...

In Episode 111 of Azure Cosmos DB TV, host Mark Brown is joined by Yohan Lasorsa to explore how developers can build agent-powered applications using a fully serverless architecture. This episode focuses on a practical, end-to-end example that demonstrates how transactional application data and AI-driven experiences can coexist on a single platform...

A hands‑on walkthrough of building MCP servers that can plug AI applications into Azure Cosmos DB The Model Context Protocol (MCP) has established itself as the ubiquitous standard for connecting AI applications to external systems. Since its release, there have been implementations across various programming languages and frameworks, enab...

Account Key Usage Metadata is a new security and observability feature that helps Azure Cosmos DB customers avoid service disruptions during key rotations. It provides visibility when each account key was last used, allowing teams to make informed decisions before rotating or migrating to Entra ID.  This feature addresses a common challenge of r...

We're excited to announce the Azure Cosmos DB MCP Toolkit in public preview. This open-source implementation of the Model Context Protocol (MCP) gives AI agents and LLMs direct, secure access to Azure Cosmos DB. The toolkit bridges intelligent applications and globally distributed databases, enabling AI agents to query, search, and understand data ...
