WHAT IT DOES

What import_terminology does on AWS IoT SiteWise MCP Server

AI agents use import_terminology 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 import_terminology needs a policy

Import operations create or bulk-load data into systems. Without evidence of destructive, financial, or execution capabilities, this falls into Write category. Severity is medium because bulk terminology imports could affect downstream processes or system behavior if corrupted, but the operation is reversible.

From the tool's definition Tool name 'import_terminology' suggests creating or adding terminology data to a system. The empty description limits certainty, but 'import' typically indicates ingesting external data into a system, which is a Write operation (reversible modification).
