Microsoft Gives Copilot Tools in Azure Cosmos DB Extension
Microsoft published a post on the Azure Cosmos DB developer blog on August 18, 2026 describing recent updates to the extension for Visual Studio Code. Everything below comes from that first party post.
Transcript
Microsoft gave GitHub Copilot tools inside the Azure Cosmos DB extension for Visual Studio Code.
Copilot can inspect the query and connection context, sample the container schema, apply a query to the editor, and run it. Sampling infers real property names.
Sampling and execution each ask permission. Existing Cosmos DB permissions still apply. The Agent Kit skill carries over one hundred recommendations, usable from Claude Code and Cursor.
Microsoft wrote this about its own product. No pricing, no user count, no independent testing. The Migration Assistant is only in preview, and MCP mode is self-hosted.

Every claim in this video comes from the top ranking coverage of this topic. The claims and where each one came from:
- The Azure Cosmos DB Visual Studio Code extension now gives GitHub Copilot tools for working with the Cosmos DB for NoSQL Query Editor. Copilot can: Find an open Query Editor connection, Open or focus the correct Query Editor, Inspect the current query and connection context, Sample the container schema, Apply a generated query to the editor, Execute the query and wait for its completion.(Microsoft's official announcement, Azure Cosmos DB in the Agentic Era: Data Tools for Developers and AI Agents)
- Before generating a query, Copilot can sample the active container and infer the property names and types it actually finds. The query is then based on the developer's data instead of the model's best guess.(Microsoft's official announcement, Azure Cosmos DB in the Agentic Era: Data Tools for Developers and AI Agents)
- Sampling isn't silent. It reads data and consumes request units, so the extension asks first. Query execution follows the same rule.(Microsoft's official announcement, Azure Cosmos DB in the Agentic Era: Data Tools for Developers and AI Agents)
- Existing Cosmos DB permissions continue to determine what the connected identity is allowed to do.(Microsoft's official announcement, Azure Cosmos DB in the Agentic Era: Data Tools for Developers and AI Agents)
- The Azure Cosmos DB Agent Kit skill covers more than 100 recommendations across data modeling, partition-key design, query optimization, SDK usage, indexing, throughput, global distribution, monitoring, vector search, full-text search, and agent application patterns.(Microsoft's official announcement, Azure Cosmos DB in the Agentic Era: Data Tools for Developers and AI Agents)
- The Agent Kit brings that knowledge into everyday coding across GitHub Copilot, Claude Code, Codex, Cursor, Gemini CLI, and other compatible agents.(Microsoft's official announcement, Azure Cosmos DB in the Agentic Era: Data Tools for Developers and AI Agents)
- The AI-assisted Migration Assistant, currently in preview, helps teams examine a relational workload before moving it to Cosmos DB.(Microsoft's official announcement, Azure Cosmos DB in the Agentic Era: Data Tools for Developers and AI Agents)
- One detail is worth being plain about: this is not a hosted, managed MCP service. It is optional, runs under the developer's control, and must be enabled explicitly.(Microsoft's official announcement, Azure Cosmos DB in the Agentic Era: Data Tools for Developers and AI Agents)
