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