### Description (declared)

# Simple PostgreSQL MCP Server

This is a template project for those looking to build their own MCP servers. I designed it to be dead simple to understand and adapt - the code is straightforward with MCP docs attached so you can quickly get up to speed.

## What is MCP?

*TL;DR - It's a way to write plugins for AI*

Model Context Protocol (MCP) is a standard way for LLMs to interact with external tools and data. In a nutshell:

- **Tools** allow the LLM to execute commands (like running a database query)
- **Resources** are data you can attach to conversations (like attaching a file to a prompt)
- **Prompts** are templates that generate consistent LLM instructions

## Features

This PostgreSQL MCP server implements:

1. **Tools**
   - `execute_query` - Run SQL queries against your database
   - `test_connection` - Verify the database connection is working

2. **Resources**
   - `db://tables` - List of all tables in the schema
   - `db://tables/{table_name}` - Schema information for a specific table
   - `db://schema` - Complete schema information for all tables in the database

3. **Prompts**
   - Query generation templates
   - Analytical query builders
   - Based on the templates in this repo

## Prerequisites

- Python 3.8+
- [uv](https://github.com/astral-sh/uv) - Modern Python package manager and installer
- npx (included with Node.js)
- PostgreSQL database you can connect to

## Quick Setup

1. **Create a virtual environment and install dependencies:**
   ```bash
   # Create a virtual environment with uv
   uv venv
   
   # Activate the virtual environment
   source .venv/bin/activate  # On Windows: .venv\Scripts\activate
   
   # Install dependencies
   uv pip install -r requirements.txt
   ```

2. **Run the server with the MCP Inspector:**
   ```bash
   # Replace with YOUR actual database credentials
   npx @modelcontextprotocol/inspector uv --directory . run postgres -e DSN=postgresql://username:password@hostname:port/database -e SCHEMA=public
   ```
