How secure is the Leave Hacker MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Leave Hacker holds up.
Official endpoint
Operated by Leave Hacker (leavehacker.app) 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 Leave Hacker adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps
Connect your gate
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Pick Leave Hacker
Choose Leave Hacker in the gate directory. No sign-in needed.
Use it anywhere
Leave Hacker's tools are live in every AI client you've connected — with rules and logging built in.

https://leavehacker.app/mcpQuestions, answered
