Gather PostgreSQL Connection Information
You will need the following values to connect to your PostgreSQL instance:
POSTGRES_HOST: Hostname or IP address of your PostgreSQL server (e.g.,127.0.0.1)POSTGRES_PORT: The port number (default is usually5432or as set by your server)POSTGRES_USER: Your PostgreSQL username (should have at least read permissions)POSTGRES_PASSWORD: The password for your PostgreSQL userPOSTGRES_DB: The database name you wish to connect to (e.g.,ecommerce)
Log in to the FastMCP Connection Interface
Open the MCP tool’s connection setup interface in your FastMCP dashboard.
Click “Install Now” to Add Environment Variables
Use the “Install Now” button to access the environment variable input form for your MCP PostgreSQL Operations server.
Enter the Required Environment Values
Fill in the following fields in the connection setup form:
- POSTGRES_HOST (e.g.,
127.0.0.1or your server address) - POSTGRES_PORT (e.g.,
5432or your custom port) - POSTGRES_USER (your PostgreSQL username)
- POSTGRES_PASSWORD (your PostgreSQL password)
- POSTGRES_DB (the main database to connect to, e.g.,
ecommerce)
These are required for connection. You may leave other fields at defaults unless otherwise needed.
- POSTGRES_HOST (e.g.,
Optionally Set Advanced Parameters
- If you want to connect to a different database, set
POSTGRES_DBto your target. - Use other variables (like
MCP_LOG_LEVEL) only if you want to customize logging or server settings.
- If you want to connect to a different database, set
Save and Test the Connection
- After entering the details, save the configuration.
- Use the test or connect feature (if available) to verify the connection to your PostgreSQL server is working.
Start Using the MCP PostgreSQL Tools
- Once connected, you can use natural language queries to analyze and monitor your databases directly from the FastMCP interface.
Tip: If connecting to an external or cloud-hosted PostgreSQL (like AWS RDS/Aurora), make sure network/firewall rules permit access, and the user has the required read permissions.
Troubleshooting:
If you encounter connection errors, double-check the values you provided, ensure the database is running, and verify network access from your FastMCP server to the database.
