Validate and interpret payment response status
AI agents call validate_payment_response to retrieve information from Satim Payment Gateway Integration without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Although this tool operates within a Financial domain (payment gateway context), its specific function is to validate/parse existing payment responses rather than initiate transfers, process refunds, or commit financial obligations. It performs a read-like operation on response data. However, the financial context prevents a lower severity.
From the tool's definition Tool name 'validate_payment_response' and description 'Validate and interpret payment response status' indicate this tool reads and interprets payment gateway responses without initiating transactions or moving money.

PolicyLayer is an MCP gateway — it sits between your AI agents and Satim Payment Gateway Integration, and nothing reaches the server without passing your rules. This is the rule we recommend for validate_payment_response:
{
"version": "1",
"default": "deny",
"tools": {
"validate_payment_response": {}
}
}validate_payment_response is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
