FAQ from PostgreSQL Products MCP Server

What database schema does the server require?

The server connects to any PostgreSQL database, but it is designed for a schema containing product information. No specific table structure is enforced beyond being reachable by SELECT queries.

What transport or authentication does the server use?

The server uses PostgreSQL connection credentials provided via environment variables (PGHOST, PGPORT, PGUSER, PGPASSWORD, PGDATABASE). It does not implement additional authentication or transport layers beyond standard MCP.

Can the server modify or insert data?

No. The run_sql_query tool only accepts SQL SELECT statements, making it read-only by design.

Node.js v18 or later, npm or yarn, and access to a PostgreSQL database with the appropriate credentials.

Is the server limited to a specific MCP client?

No. It works with any MCP-compatible client that supports the configuration format (e.g., Claude Desktop, Cline).
