PostgreSQL & DuckDB

MCP-DB provides a database connectivity server that enables AI assistants to interact with PostgreSQL databases and Parquet files. Built with TypeScript and Node.js, it offers tools for executing SQL queries (read, create, update, delete) against PostgreSQL databases and querying Parquet files using DuckDB, with support for files stored in Google Cloud Storage. The server handles database connections, query execution, and result serialization, making it ideal for data analysis workflows, database management, and extracting insights from structured data sources without requiring direct database access credentials in the conversation.
