WHAT IT DOES

What CreateCodeConnection does on AWS IoT SiteWise MCP Server

AI agents use CreateCodeConnection 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 CreateCodeConnection needs a policy

The 'Create' prefix places this in the Write category—reversible resource creation. Severity is medium due to potential blast radius if an agent misconfigures connections, which could affect system integrations or security posture. Confidence is lowered from 0.7 to 0.6 due to the empty description providing no specific detail about what effects this tool has or what it connects to.

From the tool's definition Tool name 'CreateCodeConnection' suggests creating a new connection resource. The empty description prevents definitive classification, but the verb 'Create' indicates data creation rather than read-only or destructive operations.
