Perplexity

Query your data catalog from the CLI

The `search_assets` tool lets you locate Atlan database schemas directly from your command line using Claude Code. You do not need to open a browser to find where a specific table is cataloged in Atlan. Claude Code prints the Atlan asset details directly to stdout, allowing you to pipe the schema into other terminal utilities. This speeds up your Atlan shell scripting and local data analysis.

Automate policy checks in Claude Code

The `list_classifications` tool integrates with Claude Code to run automated Atlan governance checks in your deployment pipelines. This MCP Server allows your Claude Code CLI agent to verify that database changes match your Atlan classification policies. If a migration script violates an Atlan classification rule, Claude Code flags the error and halts the pipeline. This prevents non-compliant schemas from reaching production via Claude Code.

Audit workspace users via terminal

The `list_users` tool lets you inspect active Atlan catalog accounts directly from your Claude Code shell. Claude Code queries this Atlan list to help you audit who has access to your data workspace. It's easy to combine this with Atlan `list_personas` to map users to their respective data access groups in Claude Code. It replaces complex Atlan API requests with a simple terminal prompt.
