  • In Connectors, click the Add (+) → Add custom connector, then fill out:

      Server URL

      https://mcp.dataself.com

      Click Add to confirm.

  • Enable All Actions: Recommended: After adding the connector, Claude will ask how much access to grant. To allow full query capability, you need to enable all actions. Find the newly added Dataself MCP+ - Data warehouse connector in your integrations list. Click it to open its settings and look for the Permissions or Actions section. 

    • Select Always allow (or the equivalent option that grants full tool access). This allows Claude to list tables, run queries, and return results from your SQL Server.

Start Asking Questions

Open a new chat in Claude. The Dataself MCP+ - Data warehouse connector is now active. You can start with broad exploration questions and then go deeper from there. For example:

  • "What tables are available in the database?"

  • "Show me total sales by month for the last 12 months"

  • "How many active customers do we have by region?"

  • "What is the current inventory level by warehouse?"

  • "Compare sales performance this year versus last year by product category"

Claude may ask for your permission the first time it runs a query tool in a new session. Click Allow to proceed. You can also click the tool call to expand and inspect the exact query that was executed.
