WHAT IT DOES

What identity_update_workload_identity does on AWS IoT SiteWise MCP Server

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

WHY IT NEEDS A POLICY

Why identity_update_workload_identity needs a policy

The tool name contains 'update' which implies a Write operation that modifies existing identity/authentication configuration. Workload identity changes can have significant security implications as they control access permissions. However, the description is empty, which lowers confidence. Given it's on an AWS IoT SiteWise server, it likely modifies identity settings for workloads.

From the tool's definition Tool name 'identity_update_workload_identity' suggests an update operation on workload identity configuration
