This guide shows you how to run a Snow Leopard MCP server using FastMCP and connect it to an MCP client.

Prerequisites

Don’t have data? Load the sample Northwind dataset into a PostgreSQL database that Snow Leopard Cloud can reach, such as a hosted Neon or Supabase database. Run the dataset’s northwind.sql script against your database, then add the database as a data source in your instance.

Run the Snow Leopard MCP server

Clone the example server:
Set your environment variables:
Run the server:

Customize the tool description (optional)

The tool’s docstring tells agents when and how to use it. Edit server.py to describe your specific data:

Connect to the MCP server

You can now connect the server to any application that supports MCP. Below we show how to connect with Claude Desktop.

Claude Desktop

Add the server to your Claude Desktop configuration (claude_desktop_config.json):
Now you can ask Claude questions about your data.
