# API Atlas

> A free, public directory of APIs and MCP (Model Context Protocol) servers.
> 10,161 records grouped into 53 canonical topics,
> compiled from four public sources: apis.guru, public-apis, the official MCP
> registry, and the awesome-mcp-servers list. Browsing requires no account and
> no API key.

API Atlas is operated by Zordon Intelligence sp. z o.o. (Łódź, Poland).
The catalogue is informational: entries link to each provider's own
documentation, and the site tracks no users — no accounts, no analytics,
no cookies.
