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

WHY IT NEEDS A POLICY

Why browser_type needs a policy

The tool name 'browser_type' does not clearly map to any obvious AWS IoT SiteWise operation, and the description is empty. 'browser_type' could suggest a browser automation action (typing into a browser field), which would be Execute category, but this is highly speculative given the IoT SiteWise context. Without a description, confidence is very low and categorizing as Other is most appropriate.

From the tool's definition Tool name is 'browser_type' but description is empty or uninformative; cannot determine what the tool does from available information.
