Dataki for Claude Code

02Ask it

What to ask in Claude Code

The assistant finds your sources, learns what the columns mean and writes the SQL. Dataki runs it read-only, and every answer shows its query.

Which tables in the billing database hold subscriptions, and how do they join to customers?

Answered from get_data_context: the tables, columns and types, plus any metric definitions and join paths your team has recorded for that source.

How many users signed up each day since Monday's release, and how does that compare with the week before?

The assistant writes the SQL and Dataki runs it read-only. The query comes back with the answer, ready to check.

Are there any orders without a matching customer? Show me the ten most recent.

A production data check in one sentence, with no SQL client to open and no connection string in your editor.

Put a chart of daily signups for the last 90 days on a dashboard called Growth.

save_dashboard turns it into a live Dataki dashboard with its own link. It refreshes on its own, and anyone you share it with can open it, no editor needed.

03What it can reach

Any source you connect to Dataki

Claude Code reaches every source your Dataki account can open, and one question can draw on several of them.

04Worth knowing

What Claude Code gets, and what it never does

Treat the key like a password
It acts as you and reaches what you can reach in Dataki. Every key has daily limits on queries and bytes scanned, every query it runs is logged under its name, and you can revoke it from Dataki at any time. Keep it out of your repositories.
No connection string on your machine
Claude Code holds one revocable key. The database credentials stay encrypted in Dataki, and every query runs with a read-only role.
Your app's data, kept apart from your code
Dataki answers from the database: signups, orders, events. It never sees your code.

More on the server itself, and every tool it offers, on the MCP server page. How credentials, keys and the query log work: security and governance.

Dataki and Claude Code

How do I connect Claude Code to a PostgreSQL database?
Connect the database to Dataki with a read-only user, create a Dataki API key, and run: claude mcp add --transport http dataki https://dataki.ai/api/mcp --header "Authorization: Bearer YOUR_DATAKI_KEY". Claude Code can then read the schema and run read-only queries through Dataki.
Does Claude Code get my database password?
No. Your database credentials stay encrypted in Dataki and never reach Claude Code or any model. Claude Code calls Dataki's MCP server, Dataki runs the SQL with a read-only role, and only the results reach the conversation.
Can Claude Code change or delete data through Dataki?
No. Dataki is read-only end to end: any statement that changes data is refused before it runs, and the connection itself uses a role that cannot write. Claude Code can create and edit Dataki dashboards, which live in Dataki, never in your database.
Which databases can Claude Code query through Dataki?
Any source connected to Dataki: Google BigQuery, PostgreSQL, MySQL, Amazon Redshift, Supabase, Google Sheets and uploaded CSV or Excel files, including hosted databases such as Neon, Amazon RDS, Cloud SQL and PlanetScale. Google Analytics 4, Firebase, Search Console, Firestore and Stripe work through their exports to BigQuery. One question can draw on several sources.
