What list_backups does on Mcp

Why list_backups is rated Low
This tool performs a query/list operation to retrieve information about existing backups. It has no side effects, does not modify data, execute code, delete resources, or commit financial transactions. The blast radius of misuse is minimal—an unauthorized listing of backups may expose metadata but does not affect system integrity or operations.
From the tool's definition Tool name 'list_backups' with description 'List all Memorystore for Valkey backups' indicates a read operation that retrieves and lists backup metadata without modifying or executing actions.
Attacks that exploit this kind of access
The rule that runs list_backups safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_backups, this is the rule to start with:
list_backups is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Mcp, apply this rule, and every list_backups call is checked against it from then on.
