# Agency Check

> A second look before your AI agent buys, sends, books, shares, signs up, or connects an app. Agency Check is a remote MCP server from Cyber Strategy Institute. It returns one advisory Decision Card per check: Ready to review, Clarify one thing, or Pause and verify. It reviews only what it is sent and never acts, contacts anyone, or blocks anything.
