SIPFlow

Sipflow MCP is a SIP/VoIP/telecom grounding layer and PCAP analyzer: - Hybrid search across a curated VoIP corpus — ~40 vendor stacks, 60+ RFCs, STIR/SHAKEN, ATIS branded-calling specs - Vendor detection from a trace or a config blob (Kamailio, OpenSIPS, FreeSWITCH, Asterisk, SIP.js, JsSIP, ...) - Trace tools — minimize noisy headers, render SIP ladders as Mermaid, lint/diff/parse messages - Config review for Kamailio / OpenSIPS / FreeSWITCH / Asterisk with risk flags - SDP parse + offer/answer compare - STIR/SHAKEN Identity header validation and attestation explainer - E.164 number validation, response-code troubleshooter, DNS NAPTR/SRV + TLS cert diagnostics - One-shot hydration of `sipflow.dev/share/<token>` URLs All tools are read-only. Every result carries a verbatim `source_url` so the agent cites real RFC sections and vendor docs instead of hallucinating directive names or response-code semantics. A skill (`/sip-debugger`) and a file-scoped rule ship with the plugin so the agent reaches for these tools automatically when you're editing SIP material.
