Frisk MCP server

Frisk is a small helper that checks whether the other side of a payment looks safe before your AI agent sends money. It looks at the address you are paying, the address the seller is asking for, the web address used, and your spending limits. It is handy for anyone building or running AI agents that pay for things on their own.

What this MCP server does

You ask your AI to check a payment before it goes out. The AI calls this helper, and the helper runs a set of checks on the details you gave it. It looks at whether the address is well formed, whether the address the seller asked for matches the one you named, whether the web address is secure, and whether the amount fits your spending limit. Then it hands back a verdict of allow, review, or block, along with a trust score and plain reasons. Your AI reads that and decides what to do next.
