List available backups for a managed database.
AI agents call list_backups to retrieve information from Vultr MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists existing backup data without creating, modifying, deleting, or executing any operations. It is a read-only query operation with minimal security risk, as viewing backup metadata does not alter system state or pose significant risk even if misused by an agent.
From the tool's definition Tool name is 'list_backups' and description states it 'List available backups for a managed database' - purely a query/retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access list_backups gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Vultr MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for list_backups:
{
"version": "1",
"default": "deny",
"tools": {
"list_backups": {}
}
}list_backups is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List available backups for a managed database. It is categorised as a Read tool in the Vultr MCP MCP Server, which means it retrieves data without modifying state.
Register the Vultr MCP server in PolicyLayer and add a rule for list_backups: 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 Vultr MCP. Nothing to install.
list_backups 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_backups 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_backups. 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.
list_backups is provided by the Vultr MCP server (rsp2k/mcp-vultr). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Vultr MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
