## Why rotate_agent_key is rated Medium

This tool modifies security credentials (an API key) reversibly—the old key is replaced, not deleted, and the operation can be undone by rotating again. While it affects access control in a financial system (AgentPay manages spending authorization), the tool itself does not move money or directly authorize transactions; it changes authentication material. This makes it Write rather than Financial or Execute.

From the tool's own definition: "Tool rotates (modifies) an API key for an agent within an authorization system that controls real spending. Description: 'Rotate the API key for the current agent and return the new key.'"

## Use case

AI agents use rotate_agent_key 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.
