WHAT IT DOES

What rotate_agent_key does on AgentPay

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.

RISK

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 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.'

Attacks that exploit this kind of access

RECOMMENDED RULE

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

rotate_agent_key Rate-limited

rotate_agent_key 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.
