FAQ from PostgreSQL MCP Server

What is the purpose of this server?

It provides an MCP interface for executing PostgreSQL queries, enabling AI assistants (specifically within Cursor IDE) to interact with a PostgreSQL database.

What are the dependencies?

Node.js version 18.0.0 or higher, a running PostgreSQL server for target operations, and network access to that PostgreSQL instance.

How do I configure the connection?

Set the POSTGRES_CONNECTION_STRING environment variable in your MCP settings. Optionally, set POSTGRES_SSL_CERT_PATH to the path of an SSL root certificate.

Does it support SSL/TLS?

Yes. The server validates connection strings and supports SSL/TLS connections for secure communication with the database.

Where does the data live?

The server only queries the remote PostgreSQL database specified in the connection string; it does not store data locally.
