THE RISK

Critical Risk

Accepting a PayPal dispute claim triggers a financial settlement process where money is transferred back to the claimant. This is a Financial action because it directly commits to a financial obligation (refund/chargeback), and it is critical severity because it can result in irreversible monetary loss if misused by an AI agent.

From the tool's definition 'Accept a dispute claim' - accepting a dispute claim results in a financial outcome where funds are returned to the buyer, representing an irreversible financial obligation/loss

HOW TO CONTROL ACCEPT_DISPUTE_CLAIM

PolicyLayer is an MCP gateway — it sits between your AI agents and PayPal, and nothing reaches the server without passing your rules. This is the rule we recommend for accept_dispute_claim:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "accept_dispute_claim": {
      "deny_if": [
        {
          "conditions": [],
          "on_deny": "Requires human approval."
        }
      ]
    }
  }
}

Any call to accept_dispute_claim is blocked until a human approves it. The rest of the server keeps working.
