MCP PostgreSQL Server

A Model Context Protocol (MCP) server that enables AI models, particularly Claude, to interact with PostgreSQL databases through standardized tools like query, execute, list_schemas, list_tables, and describe_table. Version 0.1.3 is the latest stable release, currently in early development with active updates. It supports both PostgreSQL-style ($1, $2) and MySQL-style (?) parameter placeholders for prepared statements, multi-schema operations, and TypeScript types. Unlike generic database MCP servers, it is purpose-built for PostgreSQL, offering secure connection handling via environment variables and automatic cleanup. It is designed for use with MCP-compatible hosts (e.g., Claude Desktop) and should not be confused with direct database client libraries.
