Before you install

Basic checks: 1 of 1 passed
Runs on the maker’s server: what you ask it goes through their server.
The registry lists no key to fill in.

You need

Common questions

Is Sipflow safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.0) reached the registry 6 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Sipflow MCP

SIP/VoIP/telecom grounding for AI agents. Vendor docs across ~40 stacks,

60+ RFCs, STIR/SHAKEN, trace and config analysis - every answer cites a

verbatim source_url.

Sipflow is a hosted, read-only Model Context Protocol server. It gives your editor or agent ~20 tools that ground SIP/VoIP answers in a curated corpus instead of training-data recall.

Live endpoint: https://mcp.sipflow.dev/mcp (Streamable HTTP)
Web app: https://www.sipflow.dev
Install page (one-click + all clients): https://www.sipflow.dev/tools/mcp

Install

Cursor (one-click)

Install Sipflow in Cursor

Or from the Cursor Marketplace. This repo also ships as a Cursor plugin with a bundled Skill and Rule (see What's in this repo below).

Cursor (manual) - `~/.cursor/mcp.json`

"mcpServers": { "sipflow": { "url": "https://mcp.sipflow.dev/mcp" } } }

VS Code - `.vscode/mcp.json` or user `settings.json`

"servers": { "sipflow": { "type": "http", "url": "https://mcp.sipflow.dev/mcp" } } }

Requires VS Code 1.99+ with the GitHub Copilot extension.

Claude Desktop - `claude_desktop_config.json`

Claude Desktop is stdio-only, so use the mcp-remote shim:

"mcpServers": { "sipflow": { "command": "npx", "args": ["-y", "mcp-remote", "https://mcp.sipflow.dev/mcp"] } } }

Claude Code (CLI)

claude mcp add --transport http sipflow https://mcp.sipflow.dev/mcp

Codex CLI - `~/.codex/config.toml`

[mcp_servers.sipflow]

url = "https://mcp.sipflow.dev/mcp"

Cline - Settings -> MCP Servers -> Edit JSON

"mcpServers": { "sipflow": { "url": "https://mcp.sipflow.dev/mcp" } } }

Continue - `~/.continue/config.yaml`

mcpServers:

name: sipflow transport: type: streamable-http url: https://mcp.sipflow.dev/mcp

Windsurf - `~/.codeium/windsurf/mcp_config.json`

"mcpServers": { "sipflow": { "serverUrl": "https://mcp.sipflow.dev/mcp" } } }

Goose - `~/.config/goose/config.yaml`

What's in this repo

File / Folder	Marketplace	Purpose
`server.json`	Official MCP Registry	Canonical server descriptor. PulseMCP auto-ingests from here.
`smithery.yaml`	Smithery	Remote HTTP listing.
`.cursor-plugin/plugin.json`	Cursor Marketplace	Plugin manifest.
`mcp.json`	Cursor plugin auto-discovery	Points the plugin at the remote endpoint.
`skills/sip-debugger/`	Cursor plugin	"When to use Sipflow" playbook surfaced as `/sip-debugger`.
`rules/sip-grounding.mdc`	Cursor plugin	Auto-attaches when editing `.pcap`, kamailio/opensips/freeswitch/asterisk configs, dialplans, `.sdp`.
`assets/logo.svg`	All	Logo.

The Cursor-specific files (.cursor-plugin/, mcp.json, skills/, rules/) are silently ignored by non-Cursor marketplaces - they only parse their own manifest.

Tool catalog

All tools are read-only. The only outbound IO is dns_diagnose_sip_target (DNS + TLS handshake) and validate_stir_shaken_identity (cert fetch).

Discovery / grounding - search_sip_docs, lookup_response_code, lookup_sip_header

Detection - detect_sip_stack, detect_sip_vendor_from_config

Traces - minimize_sip_trace, render_sip_ladder, sip_ladder_example, lint_sip_request, parse_sip_message, diff_sip_messages

Config review - review_sip_config, webrtc_sip_checklist

SDP - parse_sdp, compare_sdp_offer_answer

STIR/SHAKEN - validate_stir_shaken_identity, stir_attestation_explainer

Telecom - validate_e164_number, troubleshoot_response_code

Network - dns_diagnose_sip_target (rate-limited)

Share hydration - fetch_sipflow_share for sipflow.dev/share/ URLs

Resource - sipflow://docs/{vendor}/{id} for a single corpus chunk

Corpus coverage

~40 vendor stacks: Kamailio, OpenSIPS, FreeSWITCH, Asterisk (PJSIP + chan_sip), SIP.js, JsSIP, FreePBX, 3CX, OpenSER, Twilio, Cisco, ...
60+ RFCs: SIP, SDP, RTP, WebRTC core
STIR/SHAKEN: RFC 8224/8225/8226/8588/9027/9795
Branded calling: ATIS-1000074, ATIS-1000094, ATIS-1000084, CTIA BCID

Local development (Cursor plugin)

Test the plugin locally by symlinking this repo into Cursor's local plugin folder:

ln -s "$PWD" ~/.cursor/plugins/local/sipflow

Run Developer: Reload Window in Cursor. You should see:

sipflow server in Settings -> Features -> Model Context Protocol
sip-debugger skill under Settings -> Rules (Agent Decides)
sip-grounding rule under Settings -> Rules

Submitting updates

When the MCP server changes, bump version in three places to keep registries in sync:

server.json -> Official MCP Registry
.cursor-plugin/plugin.json -> Cursor Marketplace
The hosted server's serverInfo.version

Then re-run mcp-publisher publish for the Official Registry. Cursor, Smithery, and Glama auto-track the default branch.
