LinkList — grounded sources for agents

Your agent, grounded in sources you vetted.

Add one endpoint to Claude Code, Codex or Cursor. Your agent searches the collection you curated and answers with the URL and the date each source was fetched.

Protocol 2025-11-25. Three tools: search_sources, list_collections, get_source.

The same question, two agents

Ungrounded

Several providers offer contractor payment APIs, including a number of well-known payroll platforms.

Plausible. Unattributable. Possibly wrong.

Checkable. You chose the source.

Works where you work

Bring your sources to your agent.

NotebookLM asks you to move your work into its app and use its model. LinkList runs underneath the agent you already have open.

NotebookLM

  • You open their app and work there.
  • 50 sources per notebook on the free tier, 300 on Pro.
  • Gemini on every tier. No model choice.

LinkList

  • You stay in Claude Code, Codex or Cursor.
  • Your agent queries the collection over MCP.
  • Any model. Any MCP client.

How it works

  1. 01

    Connect the endpoint

    One command registers LinkList with your agent. Nothing else about your setup changes.

    $ claude mcp add --transport http \
    linklist https://linklist.io/mcp

  2. 02

    Add the sources you trust

    Paste the URLs into a collection. LinkList fetches the full text, chunks it and embeds it.

  3. 03

    Ask your agent as usual

    It calls search_sources when it needs grounding, and answers with the source attached.

Questions

Which clients does this work with?
Anything that speaks MCP over streamable HTTP: Claude Code, Claude Desktop, Cursor and others. The server negotiates protocol 2025-11-25 and older revisions.
How is this different from giving my agent a web search tool?
Web search returns whatever ranks. This returns only what you added, and it tells your agent where each passage came from and when it was fetched.
Do you train on my sources?
No. Sources are fetched, chunked and embedded so they can be retrieved for your own queries. Libraries are private unless you publish them.
What happens when a source changes?
Content is hashed on fetch. Pro accounts can re-fetch on demand. Scheduled re-crawling is not shipped yet.
How do I know retrieval actually finds the right source?
Measure it. The test harness ships with the product, so you can point it at your own sources and see how often the right one comes back. We run it on ours before every release and publish what it says, including when it falls short.

Point your agent at sources you trust.
