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

Safe With Normal Controls

Excessive Permissions is the main signal, but overall risk remains within an acceptable range.

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

Recommended action: No high-risk findings were detected in this scan, but you should still apply least-privilege defaults and rescan after changes.

Suggested policy: keep this tool behind manual approval, do not allow unattended runs, and re-scan after narrowing risky permissions.

Security Findings (64)

  • 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.

  • LowAS-011

    ℹ️Missing Rate-Limit / Timeout ×21

    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.

    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.

  • 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
