Your agent gets
your databases.
Not your passwords.
Claude Code, Cursor, Zed — any MCP client — can explore your schemas and query your data through Varium SQL. Your credentials stay in your OS keychain, where they already are. Nothing gets pasted into a config file.
And it learns from your database, not a generic one: agents can read the queries your team actually runs — your joins, your filters, what takes eight seconds. No other MCP server can know that.
And agents can't write. Reads run; anything that changes data lands in your editor for you to approve. You grant one connection at a time, and every call is logged. There's a terminal built in, so the agent runs next to the schema it's reading — one button wires it up, no token on your clipboard. Point a connection at its project folder and the agent starts with your repo and your tables in front of it.
- Works with any MCP client
- No connection strings in .env files
- Read-only by default — writes need your approval
- Built-in terminal — one click to connect your agent
- Learns from your team's real query history
- Reads query plans, so it stops guessing about performance
- Shapes-only mode — write queries without sending a single value
- Reaches every database on the server, not just one
- Grant per connection, revoke instantly

Is the free version actually usable?
Absolutely. You get all core features including AI autocomplete, ER diagrams, unlimited tabs and connections, and all 8 database types — completely free. Pro adds Query Guard™, premium themes (20 exclusive), and priority support.
What exactly is Query Guard™?
It's a safety net for your database. Before running any DELETE, DROP, TRUNCATE, or UPDATE without WHERE clause, Query Guard shows a confirmation dialog. It's saved countless production databases from accidental data loss.
Can AI agents really use my databases safely?
Varium SQL runs an MCP server that any agent — Claude Code, Cursor, Zed — can connect to over localhost. You grant it specific connections, one at a time, and it can read from those and nothing else. It cannot write: statements that change data are refused and placed in your editor instead, for you to review and run. And if the data itself is sensitive, switch that connection to shapes-only: the agent then gets column types, null counts and masked formats like [email protected] instead of rows, which is enough to write a correct query and not enough to disclose anything. Every call is logged, and your passwords stay in your OS keychain.
Is my data safe?
Your queries, credentials and results never leave your machine, and there is no cloud sync and no account to create. Two things do get sent: an anonymous daily ping so we know how many people use the app, and a crash report when it crashes, with file paths stripped and anything resembling a credential discarded. Crash reporting can be turned off in settings, and the privacy policy spells out exactly what each contains.
What does 'lifetime' actually mean?
Pay once, use forever. All updates included. No renewals, no subscriptions. If we ever sunset the product, you keep your last version forever.
Can I get a refund?
Yes. 30-day money-back guarantee, no questions asked. Email us and we'll refund you within 24 hours.
