  • machinelibrary_fetch_document

    Retrieve the full text, metadata, and references of one Machine Library document. Use when: you have a `source_uri` from a search hit and need the body to quote, summarize, extract structured facts, or inspect its references. Do not use when: you have not yet found the document — call a `machinelibrary_search_*` tool first to obtain a real `source_uri`. Do not guess DOIs. Returns title, authors, a bounded abstract and body, and up to 50 references with URIs. Full text defaults to 40K characters and can be raised to 100K. Citation backlinks are opt-in because they require another billed sear…

  • machinelibrary_search_documents

    Search papers, books, patents, standards, Wikipedia, and YouTube transcripts. These sources belong to the Machine Library `documents` index. Use when: the user asks about scientific concepts, technical methods, prior art, citations, a DOI / ISBN / arXiv ID / PubMed ID, or wants peer-reviewed sources. Do not use when: the question is about news, current events, ongoing discussions, or social sentiment — call `machinelibrary_search_social` instead. For general web pages or code, use a different MCP server. Examples: "crispr base editing efficiency", "doi:10.1038/s41586-023-06924-6", "isbn:97…

  • machinelibrary_search_in_document

    Find specific passages inside one Machine Library document without reading the whole body. Use when: the document is large (size > ~20K tokens shown in `content_size_tokens`) and you only need the parts relevant to a sub-question, e.g. "what error rates does this paper report?" against a 60-page review. Do not use when: you need the entire document to summarize or quote in full — call `machinelibrary_fetch_document` instead. Do not call this without first obtaining a real URI via search. Returns no more than five passages of 2K characters each. If no passage matches, returns an empty list w…

  • machinelibrary_search_social

    Search Reddit, Telegram channels, and Discord in the Machine Library `social` index. Use when: the user asks about news, recent events, announcements, ongoing discussions, community opinions, or anything time-sensitive that wouldn't be in peer-reviewed literature. Do not use when: the question is about settled scientific knowledge, citations, or prior art — call `machinelibrary_search_documents` instead. For general web search, use a different MCP server. Examples: "openai gpt-5 release date", "site:reddit.com/r/LocalLLaMA quantization", "@telegram_channel breaking news", "kubernetes 1.33 c…
