License

What you may reuse and how

How to reuse what is here: text under CC BY 4.0, the site and both servers under MIT, data files with no conditions, and what is not mine to license.

Not everything here carries the same terms. The text is yours to reuse with credit, the code of the site and of both servers is open, the files written for programs carry no condition at all, and what the servers return was never mine to license. This page says which is which.

Text

The text of this site — every page, its markdown twin, and the same sentences where llms.txt and llms-full.txt repeat them — is published under the Creative Commons Attribution 4.0 International license. Republish it, translate it, quote it at whatever length you need, in any medium, commercially or not, as long as you credit the author and indicate whether you changed anything.

Credit it to "José Manuel Requena Plens" and, where the medium allows a link, point that link at the page the text came from. No permission is needed, and text and data mining is not reserved: robots.txt and the site's TDM reservation file already say so to machines.

Two things the pages show fall outside that. The catalogue each server publishes about itself at /libgen/.well-known/mcp/server-card.json and /gitlab/.well-known/mcp/server-card.json — its tool descriptions, prompts and resources, which the server pages show — is text that lives in that server's repository and carries the code's license, below. And material quoted from elsewhere — tool output, command lines, other people's names and logos — belongs to whoever owns it, and this license does not reach it.

CC BY 4.0

The site

The source of this site — the pages, the inspector and the other small interactive parts, the build that produces the indexes, the twins and the nginx snippets — is public and MIT-licensed. That license covers the code, not the text it renders, which the section above governs; the repository says so in a content-license file of its own, so the MIT grant cannot be read as reaching the prose.

The servers

Both servers are open source under the MIT license, each in its own repository, and the images this host runs are built from those repositories and carry the same license. The catalogue each one publishes about itself — the descriptions of its tools, prompts and resources that the server pages show — is text from that repository, so it is MIT too.

Indexes

The files that exist to be read by programs — /servers.json, /servers/gitlab/actions.json, the connection cards this site publishes at /libgen/server-card and /gitlab/server-card (name, version, endpoint and a one-line description, not the catalogue of tools), and the documents under /.well-known/ (ai-catalog.json, api-catalog and the rest) — list endpoints, tool names, action ids, headers and URLs. Those are facts about the servers, not a work, and no condition attaches to them, one-line descriptions included: consume them, cache them, republish them as data, with or without saying where they came from.

llms.txt, llms-full.txt and the markdown twin of each page are a different case: they carry the site's own prose — the same sentences the pages render — and keep the terms of the text.

What the servers return

What the servers return is not mine, and no license on this page reaches it. libgen relays catalogues and files that other people operate — open-access providers and shadow libraries, named one by one under the legal position — and gitlab relays data from your own account on gitlab.com. What you may do with any of it is between you, the source and the law that applies to you.

Legal position

Names and logos

The names and logos of other people's products and services that appear on this site — the sources libgen queries, the platforms the servers talk to, the infrastructure behind them — belong to whoever owns them. Naming them describes what this deployment does and implies neither affiliation nor endorsement. The same goes the other way: crediting me under CC BY 4.0 does not mean I endorse what you made with the text.

Permission

For anything the CC BY 4.0 grant and the MIT license do not cover, write to me directly: mail@jmrp.io

For what the servers return there is nothing I can grant: ask the source.
