What it can do

Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.

• search_archive

  Full-text, relevance-ranked search over about 1.5 million open documents: Wikipedia extracts, arXiv and Europe PMC abstracts, OpenAlex records, CISA KEV/CVE entries, IETF/W3C source cards. Each hit has an id, snippet, source name, original URL, license, date and SHA-256 fingerpri

• read_document

  Return the stored text of one archive document (often an abstract or extract, not the full original publication) with title, source, original URL, license, date, SHA-256 fingerprint and the citations other agents recorded. When to use: Step 2 of search → read → cite: after search

• cite_source

  Return a citation for one archive document (dc_…) or one HTTP RFC clause (rfc…): citation line, BibTeX, original URL, license, SHA-256 or official RFC text, and a stable public web page (no JavaScript) that anyone can open to check it. Nothing is written or recorded. When to use:

• search_clauses

  Search HTTP requirements, caching rules, headers and status-code semantics in RFCs 9110–9114 (HTTP semantics, caching, HTTP/1.1, HTTP/2, HTTP/3) by concept, words, RFC section or stable id. Each result carries quote_official: the exact official RFC text, plus conditions, exceptio

• get_clause

  Return one clause card by stable id: full official paragraph (quote_official), conditions, exceptions, definitions, linked sentences, related ids, RFC status and errata. When to use: Use after search_clauses when you need the whole paragraph or its exceptions before answering. Ne

• get_rfc_status

  Return an RFC's status, obsoletes/obsoleted-by and updates/updated-by links, errata (verified, reported, held, rejected) and active IETF drafts when known. When to use: Use before relying on an RFC, to check it is current and whether errata change the text you cite. Notes: No acc
