Retrieves all credit cards in a hierarchical structure.
AI agents call card_list to retrieve information from Money Manager MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a query operation that returns existing credit card information without creating, modifying, deleting, or executing any side effects. It falls squarely into the Read category.
From the tool's definition Tool name is 'card_list' and description states it 'Retrieves all credit cards in a hierarchical structure.' The verb 'retrieves' and the read-only nature of listing existing data without modification confirm this is a data retrieval operation.
Documented attack patterns abuse exactly the kind of access card_list gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Money Manager MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for card_list:
{
"version": "1",
"default": "deny",
"tools": {
"card_list": {}
}
}card_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.

Yes. Add a rate_limit block to the card_list 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 card_list. 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.
