WHAT IT DOES

What CreateTokenWithIAM does on AWS IoT SiteWise MCP Server

AI agents call CreateTokenWithIAM as a supporting operation in AWS IoT SiteWise MCP Server workflows.

WHY IT NEEDS A POLICY

Why CreateTokenWithIAM needs a policy

The name suggests creating an authentication token using IAM credentials, which would be a Write/Execute operation. However, the description is empty, making it difficult to determine the exact behavior. Token creation could involve write operations (creating a session/token record) or execute operations (triggering IAM authentication flows).

From the tool's definition Tool name 'CreateTokenWithIAM' and empty description provide minimal context.
