Security check

How secure is the Json Schema Validator MCP server?

Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Json Schema Validator holds up.

Verified directory serverJson Schema Validator · ngrok-free.dev

Official endpoint

Operated by Json Schema Validator (ngrok-free.dev) 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 Json Schema Validator adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
