recover_volume · CloudStack MCP Server MCP: Risk & Policy

WHAT IT DOES

What recover_volume does on CloudStack MCP Server

AI agents use recover_volume to create or update resources in CloudStack MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your CloudStack MCP Server environment.

WHY IT NEEDS A POLICY

Why recover_volume needs a policy

This tool recovers (restores) a deleted volume, making it a Write operation rather than Destructive since it reverses a deletion and restores data. The severity is high because recovering volumes affects critical storage infrastructure and could restore access to sensitive data or unintentionally modify the state of dependent systems.

From the tool's definition 'Recover deleted volume' - restores a previously deleted volume, which is a reversible Write operation that modifies infrastructure state by bringing back deleted storage resources.

Verdict

recover_volume Rate-limited

recover_volume stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about recover_volume

What does the recover_volume tool do? +

Recover deleted volume. It is categorised as a Write tool in the CloudStack MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on recover_volume? +

Register the CloudStack MCP Server MCP server in PolicyLayer and add a rule for recover_volume: 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 CloudStack MCP Server. Nothing to install.

What risk level is recover_volume? +

recover_volume is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit recover_volume? +

Yes. Add a rate_limit block to the recover_volume 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.

How do I block recover_volume completely? +

Set action: deny in the PolicyLayer policy for recover_volume. 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.

What MCP server provides recover_volume? +

recover_volume is provided by the CloudStack MCP Server MCP server (mozg31337/cloudstack-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
