Atlan for VS Code

Bring your organization's full data context into VS Code, Cursor, and Windsurf. Search the catalog, explore lineage, manage metadata, and connect any MCP-compatible AI assistant to Atlan — all without leaving your editor.

What you can do

Search assets in natural language — find tables, columns, dashboards, glossary terms, and data products across your entire stack.
Explore end-to-end lineage — trace data flow upstream and downstream across systems, right inside the editor.
View rich asset details — owners, descriptions, tags, certifications, custom metadata, and column-level info.
Connect AI assistants to Atlan — the extension auto-registers the Atlan MCP Server so GitHub Copilot, Cursor, Windsurf, and any other MCP client can answer questions grounded in your governed data context.
Update metadata in place — edit descriptions and certifications without switching tabs.

Getting started

Install the extension.
Click the Atlan icon in the Activity Bar.
Sign in with your Atlan workspace, or run Atlan: Configure Connection (API Key) to use an API key instead.
Start searching.

To generate an API key, go to your Atlan workspace → Account Settings → API Keys.

MCP Server setup

On first activation, the extension registers the Atlan MCP Server in your editor's MCP configuration so any MCP-aware AI assistant can use it. No manual setup needed.

If you ever need to re-register, run Atlan: Setup MCP Server from the command palette (Cmd+Shift+P).

Supported editors:

VS Code (with GitHub Copilot or any MCP-compatible assistant)
Cursor
Windsurf
