WHAT IT DOES

What capability_select does on Arifos

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

RISK

Why capability_select is rated Medium

An AI agent can call capability_select faster than any human can review: one bad instruction and it creates or modifies resources in Arifos by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs capability_select safely

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

capability_select Rate-limited

capability_select 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.
