# Awesome AI Catalogs [![Awesome](https://awesome.re/badge.svg)](https://awesome.re)

> A curated list of publicly available [AI Catalogs](https://agent-card.github.io/ai-catalog/), published as an AI Catalog itself.

An AI Catalog (`application/ai-catalog+json`) is a JSON document that indexes AI artifacts such as MCP servers, A2A agents, agent skills, and other catalogs. This repository's [`ai-catalog.json`](ai-catalog.json) is itself an AI Catalog whose entries are public catalogs. It is published unchanged, along with a browsable site.

- **Website:** <https://agent-card.github.io/awesome-ai-catalogs/>
- **AI Catalog:** <https://agent-card.github.io/awesome-ai-catalogs/ai-catalog.json>

Every listed catalog has been validated with the [`ai-catalog` CLI](https://github.com/Agent-Card/ai-catalog-cli) and must stay valid to remain listed.

## Using this catalog

Every listed catalog is a nested catalog entry (`application/ai-catalog+json`), so any AI Catalog client can crawl the whole list. For example, with the `ai-catalog` CLI:

```sh
ai-catalog catalog add awesome https://agent-card.github.io/awesome-ai-catalogs/ai-catalog.json
ai-catalog search mcp
```

The site's HTML also advertises the catalog with `<link rel="ai-catalog">` for agent-driven discovery.
