About Ipify
Ipify is an MCP server for checking the public IPv4 or IPv6 address visible to its service. It is for clients that need a simple IP echo, including egress checks and smoke tests.
Key features
- 01Retrieve the observed IPv4 address
- 02Retrieve the observed IPv6 address
- 03Run locally over stdio or use Pipeworx gateway
Use cases
- 01Check the gateway's egress IP
- 02Run a connectivity smoke test
MCP support
Exposes ipv4() and ipv6() as MCP tools. It can run as a local stdio server or be connected through the Pipeworx gateway, which also supplies shared meta-tools.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

Servers that need sign-in will prompt on first connect.

Details
From the project README@pipeworx/ipify
ipify MCP — keyless "what is my public IP" echo.
Part of Pipeworx — an MCP gateway connecting AI agents to 1881+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.
Tools
ipv4()— caller's IPv4 (as gateway sees it — note: this is the CF Worker egress IP, not the upstream caller)ipv6()— caller's IPv6
When called via the pipeworx gateway, the returned IP is the Cloudflare egress IP that fetched the upstream — not the LLM/agent IP. Useful for verifying egress IPs / smoke tests.
Data source
https://api.ipify.org, https://api64.ipify.org
Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"ipify": {
"url": "https://gateway.pipeworx.io/ipify/mcp"
}
}
}
What this endpoint actually serves
tools/list at https://gateway.pipeworx.io/ipify/mcp returns the tools in the table
above plus the shared Pipeworx meta-tools — ask_pipeworx,
discover_tools, search_within, remember/recall and the rest of the
gateway-wide set. So the tool count you see is larger than this table: a
single-pack endpoint currently lists roughly 30 shared tools alongside the
pack's own. The connection's initialize response states its exact scope, and
is the authoritative answer for a given day.
This is deliberate, not multiplexing by accident. The meta-tools are what let a
scoped connection answer a question this pack does not cover — via
ask_pipeworx, which routes across the whole catalog — without you adding a
second MCP server. There is currently no way to mount a pack endpoint without
them; if the extra schemas cost you more context than the routing is worth,
connect to the full gateway once rather than to several pack endpoints.
Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Both URLs reach the same gateway and the same 1881+ data sources. The
only difference is which pack's tools are listed directly; ask_pipeworx
reaches all of them from either one.
No MCP client? Call it over HTTP
curl -X POST https://gateway.pipeworx.io/v1/tools/ipv4 \
-H 'Content-Type: application/json' \
-d '{}'
No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/ipv4. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.
Standalone (no gateway account)
This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:
{
"mcpServers": {
"ipify": {
"command": "npx",
"args": ["-y", "@pipeworx/mcp-ipify"]
}
}
}
Or run it directly to confirm it starts:
npx -y @pipeworx/mcp-ipify
It speaks MCP over stdin/stdout and answers initialize/tools/list/tools/call
for only this pack's tools — none of the shared meta-tools the gateway
connection above adds. Same source, same tools, no ask_pipeworx routing.
Using with ask_pipeworx
Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:
ask_pipeworx({ question: "your question about Ipify data" })
The gateway picks the right tool and fills the arguments automatically.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
