Connect Claude to MySQL

SaturnSQL's hosted MCP server gives Claude tools to browse your MySQL or MariaDB schema, run read-only queries, and save results, without a local process or a raw connection string in a config file.

Setup

1. Add your MySQL connection in SaturnSQL (host, port, database, credentials, over SSL or an SSH tunnel).

2. Click your name in the sidebar, then Install MCP, and paste the copied prompt into Claude. It connects itself.

From there Claude can list tables, inspect columns and indexes, and run SQL against the database, scoped to the same read-only, row-limited execution SaturnSQL uses everywhere else.

Why not a self-hosted MySQL MCP server?

Self-hosted options exist, but they mean running a local process and putting a raw connection string in a config file, with no shared query library. SaturnSQL's connector reuses a connection you've already secured, and every query Claude saves lands in the same library your team already uses.

Common questions

Does it work with MariaDB too? Yes, MySQL and MariaDB connect the same way.

Can I limit what Claude can see? Connect with a MySQL user granted access to only the schemas you want exposed. See setting up a read-only database user.

Is this free? Yes, MCP access is included on every plan, including Free.
