Best MCP servers for databases
12 working options, checked Nov 8, 2026.
Short answer: the top picks for databases right now are Postgres MCP Pro, Supabase and MongoDB. We list 12 options here: 8 need a sign-in and 4 run on your own machine.
A database MCP server lets an AI assistant look at your schema, run queries and explain the results in plain language. Connect one and you can ask questions of your data without writing the SQL yourself.
Top picks
-
Postgres MCP Pro
Query, explain, and health-check PostgreSQL databases safely.
-
Supabase
Manage Supabase projects: database, auth, storage, and edge functions.
-
MongoDB
Query collections and run aggregations on MongoDB and Atlas.
-
Redis
Read and write Redis data structures from your agent.
-
MotherDuck / DuckDB
Run analytical SQL on DuckDB and MotherDuck warehouses.

How to choose
- Match your database first. A server made for Postgres, MongoDB or Redis understands that system far better than a generic one.
- Start read-only. An assistant with write access can change or delete real data. Use a read-only role until you trust the setup.
- Point it at a copy. Try new servers on a staging database, never production.
How to connect one
Here is Supabase as an example. In Claude Code, run:
claude mcp add --transport http supabase https://mcp.supabase.com/mcpFor other apps, follow our guides for Claude, ChatGPT, Cursor and VS Code.
How we picked these
We read each listing's tools and put the closest fit for this job first. Hosted servers must pass a real MCP handshake in our daily check to stay on this page, and local servers are reviewed from their source or package. That shows a server responds, not how well it works for you, and we don't run every tool in production.
Frequently asked questions
Which of these MCP servers work without signing in?
None right now. Every hosted server here needs a sign-in or an API key, and the rest run on your own machine.
Is it safe to connect an AI assistant to my database?
It can be, if you limit it. Use a dedicated read-only database user, keep credentials out of shared config files, and avoid connecting production until you have tested on a copy.
Can an MCP server write SQL for me?
The assistant writes the SQL and the server runs it. Because the server exposes your real schema, the queries are based on your actual tables instead of guesses.
How often is this list updated?
Every hosted server here is re-checked daily with a real MCP handshake, and a server drops off this page while it fails that check. Last check: Nov 8, 2026.
