WHAT IT DOES

What createCollection does on AWS IoT SiteWise MCP Server

AI agents use createCollection 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 createCollection needs a policy

The 'create' verb combined with 'Collection' suggests the tool creates a new data structure or resource. This is a Write action (reversible modification). Severity is medium because collections in AWS IoT SiteWise could contain operational metadata but the blast radius depends on what the collection stores and whether it affects live operations.

From the tool's definition Tool name 'createCollection' indicates creation of a new data collection entity. The empty description prevents full assessment of scope and reversibility.
