Point Claude at Postgres, MongoDB, Redis, SQLite or a managed cloud DB and ask questions in plain language.

10 minutes beginner 5 connectors for Founders and analysts who want answers without writing SQL

What you'll need

PostgreSQL Read-only-friendly access to a Postgres database — schema, rows, aggregates.
Optional
Supabase Managed Postgres + auth + storage when your data lives in Supabase.
Optional
MongoDB Document queries against a local or Atlas MongoDB.
Optional
Redis Key/value and cache inspection for a local or cloud Redis.
Optional
SQLite Zero-setup local SQLite file — great for prototypes and analysis.

Do this, in order

  1. 1

    Connect your database server

    Install the MCP server for my database (Postgres / Mongo / Redis / SQLite / Supabase) and confirm you can see the schema.

    You'll get: Claude lists the tables/collections it can see.

  2. 2

    Understand the shape

    Describe my schema: tables, key columns, and how they relate. Flag anything that looks off.

    You'll get: A short map of the schema plus any obvious modeling smells.

  3. 3

    Ask a real question

    How many active users signed up in the last 30 days, broken down by week? Write the query, run it, and show the result.

    You'll get: The generated query, the result table, and a one-line read of the trend.

You're done when

You get answers from your data by asking, while still seeing the exact query Claude ran — so you can trust and reuse it.

Why this workflow exists

Most database questions are one-offs: a count, a breakdown, a “did this migration actually work”. Writing the SQL by hand for each is slow, and a raw chatbot will hallucinate column names. A database MCP server lets Claude read your real schema first, then write a query that actually runs — and it always shows you the query, so nothing happens behind your back.

Pick the server that matches where your data lives. The steps are the same whether it’s a local SQLite file or a managed cloud Postgres.
