Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Tallyfern Rates (Canada) holds up.
Operated by Tallyfern Rates (Canada) (tallyfern.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
This server only exposes public data — no account and no credentials are involved when you connect.
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
If Tallyfern Rates (Canada) adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Choose Tallyfern Rates (Canada) in the gate directory. No sign-in needed.
Tallyfern Rates (Canada)'s tools are live in every AI client you've connected — with rules and logging built in.
