Why addCidToPaymentInstruction needs a policy

The 'x402 monetization' reference and 'payment instruction' language clearly indicate financial operations. Misuse could result in unintended financial commitments or monetization of content.

How to control addCidToPaymentInstruction

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

policy.json

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

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