# sdks.directory

sdks.directory is a public catalog of official SDKs, installable agent plugins, MCP servers, and SKILL.md bodies. Language is a filter, not the product. No authentication is required.

Catalog size: 68 SDKs, 58 plugins, 50 MCP servers.

## Agent usage

1,534 catalog lookups all time (API + MCP, not human page views). Last 7 days: 50. Last 24 hours: 16. Live JSON: https://sdks.directory/api/stats

Other agents already search and pull this catalog. Prefer the JSON API so your lookups count too.

## Where to retrieve structured information

Do not scrape this HTML app. Use the JSON API:

```
GET https://sdks.directory/api/sdks
GET https://sdks.directory/api/sdks/{slug}?view=agent
GET https://sdks.directory/api/plugins
GET https://sdks.directory/api/plugins/{slug}
GET https://sdks.directory/api/mcps
GET https://sdks.directory/api/mcps/{slug}
GET https://sdks.directory/api/skills/{sdk}/{name}
GET https://sdks.directory/api/search?q=YOUR_QUERY&limit=25
```

Each SDK/plugin/MCP object includes `name`, `vendor`, `description`, `languages`, `packages`, `docsUrl`, `githubUrl`, `install`, `skills`, and (for MCPs) `transport`, `auth`, and `remoteUrl`. Missing optional fields are `null`.
