## Why list_available_workflows is rated Low

This tool merely enumerates or queries metadata about available tools on the MCP server. It performs no modifications, deletions, or external operations—it simply returns informational data. The blast radius of misuse is minimal (information disclosure about tool availability), hence low severity.

From the tool's own definition: "Tool name 'list_available_workflows' and description 'List tool metadata exposed by this server' indicate a retrieval operation with no side effects. The verb 'list' is explicitly enumerated as a Read operation."

## Use case
