Find all regions where a specific plan is available.
AI agents call find_regions_with_plan to retrieve information from Vultr MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves informational data about Vultr's available plans and regions without creating, modifying, deleting, or executing any operations. It is purely a read/query operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name 'find_regions_with_plan' and description 'Find all regions where a specific plan is available' indicate a query operation that retrieves information about plan availability across regions with no modification or execution of infrastructure.

PolicyLayer is an MCP gateway — it sits between your AI agents and Vultr MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for find_regions_with_plan:
{
"version": "1",
"default": "deny",
"tools": {
"find_regions_with_plan": {}
}
}find_regions_with_plan is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Find all regions where a specific plan is available. It is categorised as a Read tool in the Vultr MCP MCP Server, which means it retrieves data without modifying state.
Register the Vultr MCP server in PolicyLayer and add a rule for find_regions_with_plan: 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 Vultr MCP. Nothing to install.
find_regions_with_plan 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_regions_with_plan 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_regions_with_plan. 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_regions_with_plan is provided by the Vultr MCP server (rsp2k/mcp-vultr). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Vultr MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
