WHAT IT DOES

What update_workspace does on Cloudera Data Visualization MCP Server

AI agents use update_workspace 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 update_workspace needs a policy

The tool modifies workspace settings but does not delete data (Destructive), move money (Financial), or execute arbitrary code (Execute). It is a standard update/write operation. Severity is medium because workspace updates could affect visibility/access for multiple users, but blast radius is limited to workspace-level settings, not data loss or cascading system impact.

From the tool's definition Tool description states 'Update an existing CDV workspace' - a reversible modification operation that changes workspace configuration or metadata without deletion or irreversible destruction.
