What is the MCP Data Pipeline Connector MCP Server?

Universal data connector for CSV, Postgres, and REST APIs via DuckDB

What you get

One MCP server for all your data sources — with cross-source SQL joins and no external query service. DuckDB runs embedded in-process, so you can join a CSV file against a Postgres table against a REST API response in a single query, entirely on your machine. Agents work with your data without needing source-specific knowledge or multiple MCP server configs.

  • Unified query interface — SQL across all connected sources via DuckDB — including cross-source joins
  • Multiple source types — CSV/JSON files, PostgreSQL databases, and REST API endpoints in a single server
  • Auto schema detection — Infers column names and types from CSV headers and Postgres metadata
  • REST caching — REST API responses are cached with a configurable TTL to avoid redundant calls
  • Schema normalization — Maps source-specific types to a standard set (string, number, date, boolean, json)
  • In-process query engine — DuckDB runs embedded — no separate query service to install or manage

Configuration and credentials

  • Node.js v20.19 or newer. - npm. - Optional: A running PostgreSQL instance for the Postgres connector.
