What list_alerts does on NDB MCP Server

AI agents call list_alerts to retrieve information from NDB MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why list_alerts needs a policy

This tool purely retrieves and queries alert data from the Nutanix Database Service environment. The filtering options (resolved, timeInterval, valueType/value) are all read-only query parameters that narrow the result set without modifying any underlying data. No side effects, state changes, or external operations are triggered. This is a standard informational read operation with minimal risk.

From the tool's definition Tool description states 'Get list of all alerts' and 'Returns a reduced set of fields for each alert.' The only operations mentioned are filtering and retrieval with no modifications, creations, deletions, or code execution.
