WHAT IT DOES

What set_move does on AWS

AI agents use set_move 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 set_move is rated Medium

This tool performs a data modification operation (moving a member between sets) that is reversible and has no destructive or financial consequences. It fits the Write category: creates or modifies data reversibly.

From the tool's definition Tool description: "Move member from one set to another" with args source, destination, member. The operation modifies data by relocating a member between sets, which is reversible (the member can be moved back).

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs set_move 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 set_move, this is the rule to start with:

set_move Rate-limited

set_move 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.

How do I block set_move completely? +
