AI agents call find_idle_resources to retrieve information from Cloudscope without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though find_idle_resources only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Finds cloud resources that are provisioned but not actively used — unattached disks, orphaned network interfaces, unused IPs, idle VMs, and empty compute plans. Returns each resource with its name, type, resource group/project, reason it is idle, and estimated monthly cost in USD. Returns an empty list if no idle resources are found. Use this when the user asks about waste, idle or unused resources, cleanup opportunities, or wants to find resources to delete to reduce costs.. It is categorised as a Read tool in the Cloudscope MCP Server, which means it retrieves data without modifying state.
Register the Cloudscope MCP server in PolicyLayer and add a rule for find_idle_resources: 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 Cloudscope. Nothing to install.
find_idle_resources 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 find_idle_resources 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 find_idle_resources. 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.
find_idle_resources is provided by the Cloudscope MCP server (cloudscope-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
