# PostgreSQL MCP Server Examples
This folder contains practical examples and use cases for using the PostgreSQL MCP Server with Large Language Models (LLMs).
## š Example Structure
- **`conversations/`** - Sample LLM conversations showing real interactions
- **`queries/`** - Example SQL queries with validation results
- **`schemas/`** - Sample database schemas for testing
- **`workflows/`** - Complete workflow examples for different scenarios
- **`configurations/`** - Configuration examples for various environments
## š Quick Start Examples
### Basic Query Example
```json
{
"name": "query",
"arguments": {
"sql": "SELECT id, name, email FROM users WHERE active = true ORDER BY created_at DESC LIMIT 10"
}
}
```
### Query Validation Example
```json
{
"name": "validate_query",
"arguments": {
"sql": "SELECT * FROM users WHERE email LIKE '%@gmail.com'",
"schema": "public"
}
}
```
## šÆ Use Cases Covered
