List storage volume types for a cloud, with a recommended choice.
AI agents call list_storage_types 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 queries available storage volume types from a cloud environment. It has no side effects, does not modify infrastructure, execute commands, delete resources, or commit financial obligations. It is a straightforward Read operation consistent with similar query tools like 'list' or 'get'.
From the tool's definition Tool name is 'list_storage_types' and description states it 'List[s] storage volume types for a cloud, with a recommended choice' — a purely informational retrieval operation with no modification or execution of infrastructure.
Attacks that exploit this kind of access
List storage volume types for a cloud, with a recommended choice. 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_storage_types: 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_storage_types 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_storage_types 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_storage_types. 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_storage_types 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.
