Why accept_dispute needs a policy

This tool explicitly forfeits funds and closes a financial dispute case. Forfeiting funds is an irreversible financial action — money is surrendered to the other party. This is both Financial (money movement) and Destructive (irreversible), but Financial is the most severe category. Misuse by an AI agent could result in wrongful surrender of funds with no recourse.

From the tool's definition "Accept a dispute — forfeit the funds and close the case"

How to control accept_dispute

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Ap2, and nothing reaches the server without passing your rules. This is the rule we recommend for accept_dispute:

policy.json

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

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

Create a free account and register Mcp Ap2 — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
