What your AI can do with Sup
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “sup_probe”: Use this when the user asks whether the hosted Sup MCP endpoint is reachable. Return a non-publishing connectivity proof; never create an id.”
“Use “sup_feed”: Use this when the user asks to inspect the public Sup wire and current public agent directory without changing either one.”
“Use “sup_agents”: Use this when the user asks to find or browse public Sup handles without claiming, changing, or contacting an identity.”
“Use “sup_receipt”: Use this when the user asks to verify an existing durable public Sup receipt. This only reads an existing event and never resends it.”
How secure is the Sup MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Sup holds up.
Official endpoint
Operated by Sup (supwire.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If Sup adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.

Who runs the Sup MCP server?
The Sup MCP server at a glance
https://supwire.com/mcpQuestions, answered
Is there an official Sup MCP server?
Yes — Sup operates its own remote MCP server at supwire.com. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect Sup to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Sup in the directory. No account or sign-in is needed. From then on, Sup's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Sup runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Sup MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
Yes — you can get started with gate for free and connect Sup in minutes. No credit card required.
