Why?

The public-apis GitHub repo (406K stars) lists 1,400+ free APIs. This package takes the best no-auth ones and makes them available to any MCP-compatible AI agent in one command.

Examples

"What's the weather in Tokyo?" Agent calls public_geo_lookup("Tokyo") then public_weather_forecast(35.68, 139.69)

"How much is Bitcoin right now?" Agent calls public_crypto_price("bitcoin")

"Find me a brewery in Portland" Agent calls public_brewery_search(city: "Portland")

"What are the holidays in Germany this year?" Agent calls public_holidays("DE")

"Look up the npm package express" Agent calls public_npm_package("express")

Optional API Keys

All tools work out of the box with zero configuration. For higher rate limits on NASA's Astronomy Picture of the Day, you can optionally set:

NASA_API_KEY=your_key_here
