WHAT IT DOES

What list_backups does on Mcp

Parameter	Type	Required	Description
`filter`	string	—	An expression that filters the list of returned backups. A filter expression consists of a field name, a comparison operator, and a value for filtering. The val
`parent`	string	Yes	Required. The location to list backups from. Format is `projects/{project}/locations/{location}`. Use `{location} = '-'` to list backups from all locations for

Parameters from the server's own tool schema.

RISK

Why list_backups is rated Low

Even though list_backups only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

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 Allowed

list_backups is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_backups": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

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.
