List service plans (VM sizes/flavors) available for a specific cloud.
AI agents call list_service_plans to retrieve information from Morpheus MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates available service plans (VM sizing options) for informational purposes. It performs a read-only query against the Morpheus infrastructure without creating, modifying, deleting, or executing any operations. The blast radius of misuse is minimal—an attacker would only gain visibility into available VM configurations, which is typically non-sensitive metadata.
From the tool's definition Tool name 'list_service_plans' and description 'List service plans (VM sizes/flavors) available for a specific cloud' indicate a query/retrieval operation with no side effects.
Attacks that exploit this kind of access
List service plans (VM sizes/flavors) available for a specific cloud. It is categorised as a Read tool in the Morpheus MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Morpheus MCP Server MCP server in PolicyLayer and add a rule for list_service_plans: 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 Morpheus MCP Server. Nothing to install.
list_service_plans 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 list_service_plans 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 list_service_plans. 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.
list_service_plans is provided by the Morpheus MCP Server MCP server (nixndme/morpheus-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
