Setup
1. Add your SQL Server connection in SaturnSQL (host, port — 1433 by default, database, credentials, over SSL or an SSH tunnel). Azure SQL Database and RDS for SQL Server both connect the same way.
2. Click your name in the sidebar, then Install MCP, and pick your client: Claude, ChatGPT, Cursor or Claude Code. You add https://mcp.saturnsql.com/mcp and sign in with your SaturnSQL account, with no API key to copy and no local SQL Server MCP server to run or maintain.
Your AI client can now ask for your table list, inspect columns and foreign keys, and run T-SQL against the database, scoped to the same read-only, row-limited execution SaturnSQL uses everywhere else.
Why not a self-hosted SQL Server MCP server?
Self-hosted options exist, but they mean a local process, a connection string sitting in a config file, and no shared query library for your team. SaturnSQL's connector reuses a connection you've already secured, and every query your AI client saves lands in the same library your team already uses.
Common questions
Does it work with Azure SQL Database? Yes, anywhere SaturnSQL can reach over TCP, with SSL required for most Azure SQL and RDS instances.
Can I limit my AI client to specific tables? Connect with a SQL Server login granted SELECT on only the schemas you want exposed. See setting up a read-only database user.
What plan do I need? The MCP connector requires the Starter plan or higher, same as SQL Server connections themselves.
Other databases
Not on SQL Server? Claude, ChatGPT, Cursor, and Claude Code all connect to PostgreSQL, MySQL, Oracle, BigQuery, ClickHouse, and Redshift the same way, or see the full MCP server overview for the rest.
