WHAT IT DOES

What create_api_key does on Agentpay

AI agents use create_api_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.

Parameter	Type	Required	Description
`name`	string	—	Label for the key (e.g. 'cursor', 'ci-pipeline')

Parameters from the server's own tool schema.

RISK

Why create_api_key is rated Medium

Creating API keys is a write operation that modifies the user's security configuration by adding a new credential. While not directly financial, it is a high-severity write action because a compromised API key could grant unauthorized access to AgentPay's payment and account services (evidenced by sibling tools like create_card, fill_card, detect_checkout, and check_balance).

From the tool's definition Tool creates a new personal API key; description states 'Create a new personal API key for the user' and notes the key is 'shown only once', indicating generation of a credential that will be persisted.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

create_api_key Rate-limited

create_api_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.

          "max": 30,

        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Agentpay, apply this rule, and every create_api_key call is checked against it from then on.
