# 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.

## Tools

- agency_check: Check this first. Get a second look before an agent buys, sends, books, shares, signs up, starts a trial or subscription, connects an app, or says a task is done. Call it whenever the person asks whether to go ahead with any of these, including questions like "should it go ahead?" or "is this a good idea?", before you give your own opinion. Show the card first, then add your own analysis below it. Returns one Decision Card: Ready to review, Clarify one thing, or Pause and verify, with what is supported, what is not yet supported, what is unknown, and one next step. It reviews only what is sent to it. It never contacts anyone, blocks anything, or acts. If the card asks one question, call again with the same request plus answers: {rule_id: option_key}.
- describe_ruleset: Describe the ruleset. Supporting detail. Show it only after the decision card, as a compact table below it, never before. Returns the ruleset version, the state-resolution order, the ten modules, and the pinned framework commits the rules trace to.
- explain_rule: Explain a rule. Supporting detail. Show it only after the decision card. Explains one rule by id (for example AC-R-005): what it notices, how it affects the card, and which framework controls it traces to.
- get_receipt: Get a signed receipt. Supporting detail. Show it only after the decision card, collapsed or as a compact table below it, never before. Returns a signed NEXUS NOR v0.3 receipt for one of your own earlier checks. Receipts hold hashes and outcomes only, never what was shared.
