WHAT IT DOES

What gcp_compute_create_instance does on GCP MCP Server

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

RISK

Why gcp_compute_create_instance is rated Medium

This tool creates a new VM instance, which is a reversible write operation that provisions cloud infrastructure and incurs costs. While it has financial implications (resource consumption), the primary action is infrastructure creation rather than financial transaction. It is Write rather than Execute because it does not run arbitrary code or trigger uncontrolled external operations—it provisions a specific resource.

From the tool's definition Tool name 'gcp_compute_create_instance' and description 'Create a new Compute Engine VM instance' indicate creation of cloud infrastructure resources.

RECOMMENDED RULE

The rule that runs gcp_compute_create_instance safely

PolicyLayer is an MCP gateway: it sits between your AI agents and GCP MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For gcp_compute_create_instance, this is the rule to start with:

gcp_compute_create_instance Rate-limited

gcp_compute_create_instance 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.

The button opens the PolicyLayer dashboard: create your workspace, connect GCP MCP Server, apply this rule, and every gcp_compute_create_instance call is checked against it from then on.

FAQ

Questions about gcp_compute_create_instance

What does the gcp_compute_create_instance tool do? +

Create a new Compute Engine VM instance. It is categorised as a Write tool in the GCP 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 gcp_compute_create_instance? +

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

What risk level is gcp_compute_create_instance? +

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

Can I rate-limit gcp_compute_create_instance? +

Yes. Add a rate_limit block to the gcp_compute_create_instance 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 gcp_compute_create_instance completely? +

Set action: deny in the PolicyLayer policy for gcp_compute_create_instance. 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 gcp_compute_create_instance? +

gcp_compute_create_instance is provided by the GCP MCP Server MCP server (ahmedselimmansor-ctrl/gcp_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
