Awesome AI Catalogs

A curated list of publicly available AI Catalogs, 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 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 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:

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.
