## Why pay_tab_list is rated Low

This tool retrieves and displays existing tab data without creating, modifying, deleting, or moving funds. It is a read-only operation that queries financial information but does not execute payments or transactions. The severity is low because misuse would only expose data visibility, not enable financial transfers or irreversible changes.

From the tool's own definition: "Tool name 'pay_tab_list' and description 'List all tabs' indicate a query/retrieval operation with no side effects. The stated purpose is to 'review tab health and optimize fund usage,' which is purely informational."

## Use case

AI agents call pay_tab_list to retrieve information from Pay Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

```json
{
  "version": "1",
