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