A SQL MCP Server for Claude
SaturnSQL runs a hosted MCP server at mcp.saturnsql.com. Connect it to Claude and it gets its own tools to list your connections, browse schemas, run queries, and save the good ones, on whichever database you already use.
This isn't a separate product bolted on afterward. It's the same connections, the same shared query library, and the same row-limited, validated query execution that the SaturnSQL editor uses, just exposed as tools instead of a UI. Queries Claude saves show up for your team; queries your team saved are ones Claude can run.
Install it in two steps
In the app, click your name at the bottom of the sidebar, then Install MCP. That creates a scoped API key and copies a setup prompt to your clipboard. Paste it into Claude, and Claude connects itself, no manual config file editing. Full details, plus manual setup for other MCP clients, are in the MCP connector guide.
What it's good for
Ask Claude things like "What tables reference the orders table?", "Find customers with no orders in 90 days and save that as a query", or "Explain what this slow query in our library is doing." Claude reads your actual schema instead of guessing at column names, runs the query against your database, and can write the result straight back into your team's shared library.
Connect Claude to your database
Every SQL engine SaturnSQL supports works the same way through MCP. A few have their own setup notes worth a closer look:
SQL Server, Redshift, ClickHouse, and DynamoDB connect the same way, one API key, one prompt.
Common questions
Is this different from the built-in AI SQL editor? Yes. The AI SQL editor is AI inside SaturnSQL's own editor. The MCP server is the reverse: it puts SaturnSQL's database access inside Claude. Use whichever fits how you work; both hit the same data.
Does Claude run queries automatically? Claude calls the tool, but query execution is read-only validated and row-limited the same way the API is. Nothing destructive runs through MCP.
Is it free? API and MCP access are included on every plan, including Free. What's plan-gated is the database engine and connection count, not the connector itself.
What can't Claude do through it? Billing, users, and account settings are rejected outright. For defense in depth, pair the connection with a read-only database user.
What about other agents, not Claude? The same server works with any MCP-capable client. If your agent doesn't support MCP, it can use the plain SaturnSQL API instead.
