How does the server prevent SQL injection?

All queries must use parameterized inputs (e.g., `$1`, `$2`) rather than concatenating user-provided values directly into SQL strings.

What are the runtime dependencies?

The server is written in Go and requires a PostgreSQL database. Database connection details are configured in a `.env` file using credentials provided by the user.

MCP server to interact with and inspect PostgreSQL DB

What the server does

This is a Model Context Protocol (MCP) server that provides an interface to interact with PostgreSQL databases. It allows you to execute queries, perform database operations, and manage transactions through a standardized API.

Execute SQL queries with parameterized inputs
Perform database operations (INSERT, UPDATE, DELETE)
Execute transactions with multiple statements
Retrieve database schema information
Secure parameter handling to prevent SQL injection
