Atlan Data Catalog

[!WARNING] The local Atlan MCP server in this repository is deprecated. Use the hosted Atlan MCP at mcp.atlan.com/mcp instead.

The local install path (cloning this repo or pip install atlan-mcp-server) is in maintenance-only mode — no new features, support not guaranteed. The hosted endpoint is the recommended way to integrate Atlan with Claude Desktop, Cursor, Codex, Databricks UC, and other MCP clients.

See the Atlan MCP overview for migration instructions.
