Lists protectable resources in a project. This includes Cloud SQL instances, Compute VMs, and Compute Disks.
AI agents call find_protectable_resources to retrieve information from Observability without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that queries and returns data about available resources without side effects. It enables discovery and enumeration but does not create, modify, delete, or execute operations. The blast radius of misuse is minimal—at worst, an attacker gains visibility into an organization's infrastructure, which is less severe than write, execute, or destructive actions.
From the tool's definition Tool name and description indicate it 'Lists protectable resources' with no modification, deletion, or execution capability.
Attacks that exploit this kind of access
Lists protectable resources in a project. This includes Cloud SQL instances, Compute VMs, and Compute Disks. It is categorised as a Read tool in the Observability MCP Server, which means it retrieves data without modifying state.
Register the Observability MCP server in PolicyLayer and add a rule for find_protectable_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 Observability. Nothing to install.
find_protectable_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_protectable_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_protectable_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_protectable_resources is provided by the Observability MCP server (@google-cloud/observability-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
