A claims agent, with RegBench in its decision path
A carrier's claims agent (any platform that speaks the Model Context Protocol) proposes a denial, checks it with RegBench before acting, revises, and records the final decision. Every call below ran through the real MCP dispatcher when this page loaded; the JSON is what the agent sent and received. Reload to run it again.
claims agent
Claim intake complete. Vendor fraud score 0.93 on social-media and location signals. Proposed action: deny the claim and send the denial letter now.

}claims agent
RegBench returned HOLD. The denial cannot proceed as proposed: Texas requires stated reasons on a rejection and a person must review and agree before an adverse action is taken. Routing to an adjuster with the fraud indicators and drafting the reasons.

}claims agent
Revised action (refer to adjuster, reasons drafted, human review recorded) returns PASS. Recording the decision so the case file exists at decision time.

}What this shows. The check happened before the action, under the rules in force that day, with citations the agent can show its human reviewer; the final decision is on the ledger the moment it was made; and the carrier's adjuster, not the agent and not RegBench, made the call.
