Identifies idle GCP Compute Engine VMs (low CPU) and unattached Persistent Disks that are wasting money.
AI agents call get_gcp_idle_resources to retrieve information from Cloud FinOps Analyst MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs read-only analysis and reporting on cloud resource status. It gathers information about idle resources to inform business decisions, but takes no actions that create, modify, delete, or execute anything. The worst-case misuse is returning unnecessary or sensitive resource information, which has minimal blast radius compared to other categories.
From the tool's definition Tool description states it 'Identifies idle GCP Compute Engine VMs (low CPU) and unattached Persistent Disks' — purely a query/analysis operation that retrieves and reports resource utilization data without modifying, executing against, or deleting any…
Attacks that exploit this kind of access
Identifies idle GCP Compute Engine VMs (low CPU) and unattached Persistent Disks that are wasting money. It is categorised as a Read tool in the Cloud FinOps Analyst MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Cloud FinOps Analyst MCP Server MCP server in PolicyLayer and add a rule for get_gcp_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 Cloud FinOps Analyst MCP Server. Nothing to install.
get_gcp_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 get_gcp_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 get_gcp_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.
get_gcp_idle_resources is provided by the Cloud FinOps Analyst MCP Server MCP server (mihirkadam19/finops-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
