Announcing Sequel MCP Servers: Make Your Database Talk Like a Human

We’ve got exciting news.

Today, we’re launching Sequel MCP servers — a powerful way to connect your databases to AI tools and let them query like humans do.

No SQL. No manual schema mapping. Just natural language, plugged into your local data.

What is Sequel MCP?

At its core, the Model Context Protocol (MCP) is a simple idea: MCP (Model Context Protocol) is an emerging protocol standard designed to facilitate structured communication between AI models (especially LLMs) and external systems like databases, APIs, or file systems.

Sequel MCP helps your MCP clients to talk to your database by acting as a bridge between your database and AI clients like Claude, Cursor, and WindSurf.

It does all this locally, with zero data leaving your machine.

Whether you’re an analyst, engineer, or data-savvy product builder — you can now talk to your database like it’s your teammate.

How It Works

Sequel MCP spins up a local server that speaks the Model Context Protocol. This server:

  • Understands your database schema
  • Accepts natural language queries from compatible AI clients
  • Translates them into SQL
  • Returns results — fast, safe, and context-aware

Once installed, AI tools like Cursor or Claude can interact with it directly.

# Install Sequel MCP CLI
npx -y @sequelsh/mcp@latest install

# Install PostgreSQL support
npx -y @sequelsh/mcp@latest install -d postgresql

Just like that, your local database becomes AI-accessible.

Supported Databases and Clients

Databases:

  • PostgreSQL
  • MySQL
  • ClickHouse

Clients:

  • Claude
  • Cursor
  • WindSurf

We’re actively adding support for more — want to contribute or request one? Open a GitHub issue.

Built for Privacy

Sequel MCP runs entirely on your machine. No external syncing. No cloud relay. No analytics. Your schema, your queries, your control.

This makes it ideal for working with sensitive, enterprise, or regulated data.

Why MCP?

We believe the future of databases isn’t just SQL. It’s natural language — grounded, safe, and just as expressive.

MCP is how we bridge that future. It’s lightweight, open, and easy to integrate with any AI client.

With Sequel MCP, you don’t need to manually copy table structures or paste query results into ChatGPT. You can just say what you need, and your database responds like a product expert.

Try It Now

You can head over to our MCP Database Registry to see all the available databases of spin up a local server for your database in seconds:

npx -y @sequelsh/mcp@latest install

Then open Cursor or WindSurf, and start chatting with your data.

🌍 Join the Protocol

MCP is not just a Sequel thing — it’s a growing standard. We’re building it in the open and encourage others to join.

Frequently asked questions

What is the Model Context Protocol (MCP) and why does it matter for databases?

MCP is an emerging protocol standard that enables structured communication between AI models (like LLMs) and external systems such as databases, APIs, or file systems. For databases, it means AI tools like Claude or Cursor can directly query your data using natural language without manual schema copying or query pasting.

Does Sequel MCP send my data to the cloud?

No. Sequel MCP runs entirely on your local machine with no external syncing, no cloud relay, and no analytics. Your schema, queries, and results stay on your machine, making it suitable for sensitive, enterprise, or regulated data environments.

Which databases does Sequel MCP currently support?

Sequel MCP currently supports PostgreSQL, MySQL, and ClickHouse. Additional database support is being actively developed, and you can request new databases or contribute via the GitHub repository.

Which AI client tools can use Sequel MCP?

Sequel MCP currently works with Claude, Cursor, and WindSurf. Once installed, these AI clients can interact with your local database directly through natural language queries without requiring any manual schema setup.

How do you install Sequel MCP for a PostgreSQL database?

Run "npx -y @sequelsh/mcp@latest install" to install the Sequel MCP CLI, then "npx -y @sequelsh/mcp@latest install -d postgresql" to add PostgreSQL support. After that, open Cursor or WindSurf and start querying your database in natural language.

Is Sequel MCP open source?

Yes, Sequel MCP is built in the open. The GitHub repository is at github.com/haxzie/sequel-mcp, and contributions, feedback, and requests for new database or client support are welcome through GitHub issues.
