# Stage0 Authorization MCP Server

> Use this tool when you need to enforce runtime authorization and prevent unauthorized actions by AI agents. It solves the problem of ensuring that AI agents only execute approved tool calls by validating them against Stage0 policies. The server takes in tool calls as input and outputs authorized or denied actions based on policy validation.
