WHAT IT DOES

What create_agent does on AgentPay

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

RISK

Why create_agent is rated Medium

This tool creates a new agent account/identity on a financial authorization system. While not immediately destructive or moving funds itself, creating agents on a spending authorization platform is a write operation with high severity due to the financial exposure it enables—a newly created agent could be used to establish unauthorized spending mandates or circumvent controls.

From the tool's definition Tool name 'create_agent' and server context (AgentPay authorization layer) indicate creation of a new agent entity. Server description emphasizes financial spending controls and real-money transaction authorization.

RECOMMENDED RULE

The rule that runs create_agent safely

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

create_agent Rate-limited

create_agent 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.
