How secure is the probe402 MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how probe402 holds up.
Official endpoint
Operated by probe402 (probe402.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 probe402 adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

Who runs the probe402 MCP server?
The probe402 MCP server at a glance
https://probe402.com/mcpQuestions, answered
Is there an official probe402 MCP server?
Yes — probe402 operates its own remote MCP server at probe402.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 probe402 to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick probe402 in the directory. No account or sign-in is needed. From then on, probe402's tools are available in every client you've connected to gate.
Do I need to host anything?
No. probe402 runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the probe402 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 probe402 in minutes. No credit card required.
