sipflow-sipflow

@Smithery

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.

Risk Summary

Block in Production

Excessive Permissions + Missing Rate Limits risk is significant. Avoid using this in production agents.

Potential impact: The agent may gain overly broad access to files, network, databases, or execution capabilities.

Recommended action: This tool should stay disabled in production agents until the flagged risks are fixed and the scan is clean.

    tool declares exec permission

    fetch_sipflow_share

    Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.

  • HighAS-003

    🔀Scope Mismatch

    fetch_sipflow_share:tool name "fetch_sipflow_share" implies read-only operation but declares exec permission

    Fix: Ensure tool names, descriptions, and permission declarations are internally consistent. Use explicit naming conventions that fully reflect actual capabilities.

    Fix: Declare explicit rate-limit, timeout, and retry configuration for all network and execution tools. Implement exponential back-off and surface resource state to the calling agent.

  • InfoAS-014

    ℹ️Dependency Inventory Unavailable ×21

    Tool did not expose metadata.dependencies or repo_url, so supply-chain coverage is limited.

Scan this tool yourself

Reproduce this audit locally, integrate into CI, or let your agent audit its own tools.

Install once, then scan any MCP server:

$ curl -sfL https://raw.githubusercontent.com/AgentSafe-AI/tooltrust-scanner/main/install.sh | bash
$ tooltrust-scanner scan --server "npx -y sipflow-sipflow"

Adjust the package name if your npm registry name differs from the tool ID. View source
