Overview

What is PostgreSQL Products MCP Server?

PostgreSQL Products MCP Server is a Model Context Protocol server that allows AI assistants to query a PostgreSQL database containing product information using read-only SQL SELECT statements. It is intended for developers who need to integrate product data into MCP-compatible clients.

How to use PostgreSQL Products MCP Server?

Configure the server in your MCP client settings (e.g., cline_mcp_settings.json) with environment variables for PostgreSQL connection details (PGHOST, PGPORT, PGUSER, PGPASSWORD, PGDATABASE). Build the TypeScript code with npm run build, then point the client to the built build/index.js file. The server exposes a single tool called run_sql_query that accepts a SQL SELECT query string.

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.

What are the runtime dependencies?

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).
