create_api_key · Payoza MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_api_key does on Payoza MCP Server

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

WHY IT NEEDS A POLICY

Why create_api_key needs a policy

This tool creates new API keys, which are credentials that grant programmatic access to the Payoza API. While the creation itself is reversible (keys can be deleted, as evidenced by the sibling 'delete_api_key' tool), the tool enables future unauthorized API access if misused. The primary concern is that an AI agent creating API keys without proper authorization could provision credentials for attackers.

From the tool's definition Tool name 'create_api_key' and description 'Create a new API key' indicate creation of credentials with persistent access.
