FAQ from MCPDatabases
What Python version is required?
Python 3.8 or higher is required.
What dependencies are needed?
The server requires psycopg2-binary, the built-in sqlite3 module, and a running PostgreSQL server with a configured database.
How do I configure database credentials?
Set the --url argument with your database connection string (e.g., postgresql://user:password@localhost:5432/ecommerce). Do not include real passwords in the config file; replace user and password with the actual values. Also update credentials in connection.py.
Can I use a different PostgreSQL port?
Yes. The default port is 5432. You can specify another port (e.g., 5433) in the connection URL.
Is there an alternative version with SSE support?
