WHAT IT DOES

What gcp_compute_set_machine_type does on GCP MCP Server

AI agents use gcp_compute_set_machine_type 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_set_machine_type is rated Medium

This tool modifies VM configuration (machine type) reversibly—the change can be undone by setting a different machine type. It affects infrastructure state but does not delete resources or execute arbitrary code. While the blast radius is significant (can degrade or upgrade compute resources, affecting performance and costs), the action is reversible.

From the tool's definition Tool name and description: 'gcp_compute_set_machine_type: Change machine type of a stopped VM'. The verb 'set' indicates modification of VM configuration; 'Change machine type' explicitly modifies infrastructure properties.

RECOMMENDED RULE

The rule that runs gcp_compute_set_machine_type 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_set_machine_type, this is the rule to start with:

gcp_compute_set_machine_type Rate-limited

gcp_compute_set_machine_type 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.

LIMIT THIS TOOL → Instant setup, no code required.

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

FAQ

Questions about gcp_compute_set_machine_type

What does the gcp_compute_set_machine_type tool do? +

Change machine type of a stopped VM. 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_set_machine_type? +

Register the GCP MCP Server MCP server in PolicyLayer and add a rule for gcp_compute_set_machine_type: 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_set_machine_type? +

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

Can I rate-limit gcp_compute_set_machine_type? +

Yes. Add a rate_limit block to the gcp_compute_set_machine_type 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_set_machine_type completely? +

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

gcp_compute_set_machine_type 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.
