WHAT IT DOES

What update_policy does on Okta MCP Server

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

WHY IT NEEDS A POLICY

Why update_policy needs a policy

The tool modifies existing policy objects reversibly (policies can be updated again or rolled back). It does not delete/destroy policies (which would be Destructive), nor does it execute arbitrary code/commands (which would be Execute).

From the tool's definition Tool name is 'update_policy' and description states 'Update an existing policy.' This modifies existing policy data.
