Katzilla is a MCP server that exposes 300+ public and government data sources through one API key for AI agents.
About
Katzilla is an MCP server that aggregates more than three hundred free public and government data sources behind a single Katzilla API key, aimed at agents that need defensible facts during research and scoping. developers often stall on idea validation because each dataset lives on a different portal with its own auth story; Katzilla compresses that into one stdio MCP package you run with npx after setting KATZILLA_API_KEY. The canonical shelf is Idea research, but the same connector supports Validate when you need numbers for positioning and Build when you embed live stats in a product demo. It is a data gateway MCP, not a visualization or ETL pipeline—your agent still chooses queries and interprets results. Get a free key from the Katzilla dashboard before registering the server in Claude Code or Cursor.
