List layouts for an instance type on a specific cloud.
AI agents call list_layouts 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 information about available layouts for instance types on a cloud without creating, modifying, deleting, or executing any operations. It is a straightforward data retrieval operation, making it a Read category tool with low severity risk. The blast radius of misuse is minimal—an AI agent could only enumerate layouts, not alter infrastructure.
From the tool's definition The tool is named 'list_layouts' and its description states it 'List layouts for an instance type on a specific cloud.' The verb 'list' indicates a read-only query operation with no side effects.

Register the Morpheus MCP Server MCP server in PolicyLayer and add a rule for list_layouts: 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_layouts 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_layouts 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_layouts. 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_layouts 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.
