What your AI can do with G3M
Real prompts you can type the moment it's connected — no setup, no docs to read.
“What can G3M do for me?”
“Show me the tools G3M exposes.”
How secure is the G3M MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how G3M holds up.
Official endpoint
Operated by G3M (g3m.co) at its documented MCP endpoint — not a third-party mirror or community re-host.
OAuth sign-in — your account, your rules
You grant access from your own G3M account and can revoke it there at any time. gate never sees your password.
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 G3M adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
G3M's server requires OAuth, so it can't be scanned anonymously — connect it in gate and the same scan runs automatically before it goes live.
Connected in three steps

Who runs the G3M MCP server?
The G3M MCP server at a glance
https://api.g3m.co/mcp/Questions, answered
Is there an official G3M MCP server?
Yes — G3M operates its own remote MCP server at api.g3m.co. 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 G3M to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick G3M in the directory. You sign in to G3M via OAuth to grant access. From then on, G3M's tools are available in every client you've connected to gate.
Do I need to host anything?
No. G3M runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the G3M 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 G3M in minutes. No credit card required.
