Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “verify_phone_number”: Verify a single US phone number: carrier-level line type (mobile, landline, VoIP, disconnected), carrier name, an activity score, and whethe.”
“Use “get_credit_balance”: Check the remaining pre-paid API credit balance for the connected NumberBroom account. Free to call — does not spend credits.”
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Numberbroom MCP holds up.
Operated by Numberbroom MCP (numberbroom.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
This server only exposes public data — no account and no credentials are involved when you connect.
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
If Numberbroom MCP adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Choose Numberbroom MCP in the gate directory. No sign-in needed.
Numberbroom MCP's tools are live in every AI client you've connected — with rules and logging built in.

No. Numberbroom MCP runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
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.
