<h3>A lightweight, read-only-by-default Postgres MCP server for data analysts and ETL developers.</h3>

</div>

## Overview

**Postgres MCP Lite** is a lightweight, open-source Model Context Protocol (MCP) server for PostgreSQL, designed specifically for **data analysts and ETL developers** who need to explore and understand database schemas and data.

This is a streamlined fork of [postgres-mcp](https://github.com/crystaldba/postgres-mcp) by [Crystal DBA](https://www.linkedin.com/company/crystaldba/), focused on **safe data exploration** rather than database administration:

- **🔍 Data Exploration** - Understand database schemas, table structures, and relationships with AI assistance
- **📊 Query Analysis** - Generate and execute SQL queries to analyze data patterns and relationships
- **🛡️ Read-Only by Default** - Defaults to restricted mode with SQL validation, preventing accidental modifications
- **🔌 Multiple [Transports](https://modelcontextprotocol.io/docs/concepts/transports)** - Supports both stdio and SSE
- **🌐 Multi-Database Support** - Connect to multiple databases simultaneously (app, ETL, analytics, etc.)

**Perfect for:**
- 📈 Data analysts exploring production databases safely
- 🔄 ETL developers understanding source and target schemas
- 🤖 AI-assisted data discovery and documentation
- 📝 Generating data analys…
