create_terminology · Amazon MQ MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_terminology does on Amazon MQ MCP Server

AI agents use create_terminology to create or update resources in Amazon MQ MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Amazon MQ MCP Server environment.

WHY IT NEEDS A POLICY

Why create_terminology needs a policy

The tool creates new data (terminology entries) but does not irreversibly delete, execute arbitrary code, or move funds. The empty description reduces confidence but the 'create_' prefix indicates Write operations. Severity is medium because misuse could add incorrect broker configuration or management terminology, causing operational confusion but not permanent loss.

From the tool's definition Tool name 'create_terminology' combined with server context (Amazon MQ provisioning/management) suggests creating or defining new terminology entries, likely configuration or reference data.
