MCP Server: PostgreSQL
Connect LLMs directly to PostgreSQL databases. Query, analyze, and interact with your data through natural language.
The Problem
Querying databases requires switching contexts, remembering schema details, and writing SQL. Non-technical stakeholders can't access data without engineering support.
The Solution
An MCP server that connects LLMs directly to PostgreSQL databases. Query, analyze, and interact with your data using natural language while maintaining security through read-only defaults.
