## Rules to follow
- Treat LibriVox recordings as public domain, as the site states; the homepage gives no further terms.
- Download files to your own storage instead of hotlinking.
- Check the LibriVox API update post for current API details before building on it.

## How an agent gets files
- LibriVox API: https://librivox.org/api/feed/audiobooks (also /audiotracks and /authors); add format=json; extended=1 adds sections and Internet Archive URLs (sign-in: none)
- Formats: json, xml, jsonp
- Not allowed: Recordings are public domain in the USA, not necessarily in other countries; check the work's status in your country
- Not allowed: API limit parameter can no longer be set above 500; use offset for more
- Not allowed: For large-scale retrieval add a delay between requests

## How to connect
- Public API
- Repository: https://github.com/mrfentmen/librivox-mcp
- Website: https://librivox.org

## Notes
Added automatically: MCP servers in the official MCP Registry connect to it. License read from the official pages.

AgentGid's catalog is curated: every entry was checked against the maker's official pages (registry, repository, license and pricing pages) on the date shown; a license value shows the quote it stands on wherever AgentGid has one. Usage numbers come from AgentGid's own scan of public repositories set up for AI coding agents. Claims by makers are reported, not tested by AgentGid.
