WHAT IT DOES

What cortex_update_organization does on Cortex

AI agents use cortex_update_organization to create or update resources in Cortex — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Cortex environment.

WHY IT NEEDS A POLICY

Why cortex_update_organization needs a policy

This tool modifies organizational configuration or metadata but does not delete data (not Destructive) nor move financial resources (not Financial). The scope is limited to organization settings rather than system-wide changes. Severity is medium because unauthorized organizational updates could affect multiple users and access controls, but the effect is reversible through subsequent updates.

From the tool's definition Tool name 'cortex_update_organization' and description 'Update an organization' indicate modification of existing organizational data. The verb 'update' is characteristic of Write category tools that create or modify data reversibly.
