Retrieve available payment options (PIX, bank slip) for the user to CHOOSE FROM. Use this tool BEFORE the user makes a purchase decision to show them what options are available. If the user already selected a payment plan, do not use this tool. This tool returns the payment plan IDs along with other details. This tool should be used every time the user asks for the list of payment plans or any other payment-type doubt. It is categorised as a Read tool in the Customer Registration MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Customer Registration MCP Server MCP server in PolicyLayer and add a rule for list_payment_plans: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Customer Registration MCP Server. Nothing to install.
list_payment_plans is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_payment_plans rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_payment_plans. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
