WHAT IT DOES

What create_smart_visual does on Cloudera Data Visualization MCP Server

AI agents use create_smart_visual to create or update resources in Cloudera Data Visualization MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Cloudera Data Visualization MCP Server environment.

WHY IT NEEDS A POLICY

Why create_smart_visual needs a policy

The tool creates a visual artifact within the Cloudera Data Visualization system, which is a reversible modification of data/resources. This aligns with Write-category semantics (create/modify). Severity is medium because unauthorized creation of visuals could lead to data exposure or confusion, but it is not destructive or financial.

From the tool's definition Tool name 'create_smart_visual' indicates creation of visual resources; sibling tools on the server (create_connection, create_dashboard, create_dataset, create_visual, etc.) are all Write-category operations that modify Cloudera Data Visualization state.
