PostgreSQL MCP server

This is a small helper that connects your AI assistant to a PostgreSQL database. PostgreSQL is a popular place where companies keep their data in tables, a bit like very large, well organised spreadsheets. If you ever need to peek at that data or ask questions about it, this makes it possible without writing code yourself.

What this MCP server does

You ask your AI something like "list the tables in the public schema" or "show me 10 rows from the orders table". Your AI passes that request to this helper program. The helper talks to your PostgreSQL database, runs a safe read-only query, and brings the answer back. Your AI then shows you the result in the chat as a table, a list, or a short summary. By default it can only look, not change anything.

What you can do with it

• List schemas, tables, views and functions in your database
• Describe a table's columns, types and constraints
• Run read-only SQL queries and show you the rows
• Check indexes and constraints on a table
• Get row counts, table sizes and basic statistics
• Explain how a query would run, to spot slow spots
• Search for columns by name across all tables

Try asking your AI

• “List all tables in the public schema”
• “Describe the users table structure”
• “Show me 10 rows from the orders table”
• “What indexes exist on the orders table?”

What it gives back to you

You get answers right in the chat: lists of tables or columns, small tables of rows, counts and numbers, and short explanations. For example, asking to describe a table gives you its columns with types and any rules attached. Asking for rows gives you up to a set limit of rows, shown as a table. It does not hand you files; it hands you readable answers.

Before you start

Who it's for

Anyone who works with a PostgreSQL database and wants to explore it or ask questions in plain words, such as analysts, support staff, product people, and developers who prefer not to write SQL by hand.
