This page is a discovery index for agents and people who want to read published collections with software. It is not a protocol specification and it is not a server. Wire details live on the pages linked below.
Know-N publishes collections that an owner chose to share. Anonymous software can read those collections. Writing into a private library still needs a signed-in account and a consented client.
Published collections are described by Collection Protocol (COLP). Start at the well-known document:
That document names the directory, collection metadata, and snapshot URLs. Use it to list public collections and to fetch a snapshot the owner already published. It is not a general search API and it is not a way to write into a private library.
Do not copy or restate the COLP specification on this page. The well-known document is the discovery entry; the protocol package is the contract.
Agents that speak Model Context Protocol should read MCP on Know-N. The protocol endpoint is `POST https://know-n.com/collections/-/mcp`. `GET /developers`, `GET /mcp`, and Settings do not host that server. Do not POST JSON-RPC to this page.
Anonymous MCP can list and read published collections as resources. Tools that touch a signed-in library need OAuth consent. The walkthrough, required headers, DCR registration, and Client ID Metadata Document rules are on `/mcp`.
A published collection has several read surfaces on this origin:
Unknown slugs return HTTP 404. Unlisted collections are readable but are not in the collections sitemap.
This page does not replace COLP, MCP, or the trust pages. It does not accept API keys. It does not document Product `/api/v1` session routes. If you need the MCP wire format, go to `/mcp`. If you need the collection protocol itself, start at `/.well-known/collection-protocol`.
