Tools & capabilities

Chatpack MCP tools 5

  • search_docsSearch bundled Chatpack documentation and the authoritative llms reference. Returns document ids, links and matching excerpts with package versions.
  • get_documentRead a complete bundled Chatpack document by id. Use llms for the authoritative integration contract or concepts/errors for troubleshooting.
  • get_integration_guideRetrieve the repository's framework setup guide with authentication guidance and the authoritative llms reference. Examples match the bundled package versions.
  • list_ui_blocksList public runtime exports of @chatpack/ui, including components, providers and utilities. Returns names accepted by get_ui_block.
  • get_ui_blockRetrieve a public @chatpack/ui export's source module and usage guide. Optionally include supporting UI modules and stylesheet. Files are reference source, not a standalone copy-and-paste component.

  • dns_lookupResolve a DNS record via `dig` (A/AAAA/MX/TXT/NS/CNAME/SOA/PTR/CAA), optionally against a specific resolver and over plain DNS/DoT/DoH
  • dnssec_checkQuery a known-validating resolver and report whether the AD bit is set (plain/DoT/DoH) — the only reliable way to confirm DNSSEC validation, since an RRSIG being present in a plain `dig` reply does not by itself prove anything validated it
  • ping_hostICMP ping (count clamped to 1-10)
  • traceroute_pathHop-by-hop path/loss report via `mtr --report` (fixed cycles, not a live/continuous run)
  • tcp_port_checkIs a TCP port open — a plain socket connect, not a port scan
  • http_checkHEAD/GET a URL and report status, redirect chain, and latency
  • http_getGET a URL and return the body. Textual types only (`text/*`, JSON, XML, JavaScript, YAML, `+json`/`+xml`), capped at 1 MiB. Refuses loopback, link-local and cloud-metadata destinations, including via redirect
  • tls_cert_checkFetch the certificate a host presents and report subject/issuer/validity/SANs
  • whois_lookupWHOIS lookup for a domain
  • asn_lookupASN + country-code lookup for an IP, or org info for an AS number, via Team Cymru's whois service — no API key or GeoIP database needed
  • current_timeCurrent date, time and weekday in an IANA timezone — the weekday is returned as data because deriving it from a date is arithmetic that fails silently. Also reports UTC and epoch, so it doubles as a clock check
  • health_checkVersion and which wrapped binaries (`dig`/`ping`/`mtr`/`whois`) are present on PATH
