WHAT IT DOES

What create_terminology does on AWS

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

RISK

Why create_terminology is rated Medium

The tool name indicates a Create operation, which is Write-category by default. Without a description, confidence is reduced. Medium severity assumes this creates terminology entries (likely reversible via update/delete) with moderate blast radius if an AI agent misuses it to create malicious or incorrect terminology entries.

From the tool's definition Tool name 'create_terminology' suggests data creation. No description provided to confirm scope or reversibility.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_terminology safely

PolicyLayer is an MCP gateway: it sits between your AI agents and AWS, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_terminology, this is the rule to start with:

create_terminology Rate-limited

create_terminology stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect AWS, apply this rule, and every create_terminology call is checked against it from then on.
