This guide explains how to set up and run your MCP server to interact with your PostgreSQL database using Claude Desktop. It should also work with MySQL, MariaDB, SQLite as it uses sqlalchemy under the hood. This project is build on top ofhttps://github.com/runekaagaard/mcp-alchemy
Note:This guide assumes you have a basic understanding of Docker, environment variables, and CLI usage.

- Download and Install Claude Desktop
Visit theClaude Desktop download pageand install the application.
3. Launch the PostgreSQL Database with Dummy Data
- Run Docker Compose Ensure Docker Compose is installed and run:docker-compose up -d
- This command will launch a PostgreSQL database onlocalhost:5432and populate it with dummy data.
4. Installuv(if not already installed)
- Installuv
Execute the following command to installuv:
curl -LsSf https://astral.sh/uv/install.sh | sh
-
Create/Update the MCP Server Configuration
Save the following JSON configuration in your MCP server config file (adjust paths if necessary):
{ "mcpServers": { "my_database": { "command": "uv", "args": [ "--directory", "/directory/where/this/app/is/located/app/", "run", "server.py" ], "env": { "DB_URL": "postgresql://postgres:password@localhost:5432/mydatabase" } } } }
- Tip:Ifuvis installed in a non-standard location, update the"command"value to reflect the full path to the executable.
