## Description

mcpo is a gateway and router that converts Model Context Protocol tools into standard REST API endpoints. It functions as a validation proxy and security layer, mapping multiple tool server configurations to unique URL paths while using standardized schema definitions to validate input parameters and output formats.

The project implements an OAuth security layer using dynamic client registration to verify identities via an authentication server. It also acts as a bridge for reverse proxies by applying configurable base paths to internal endpoints, ensuring compatibility with network load balancers.

The system manages tool server integration through configuration-driven loading and dynamic routing, providing a centralized hub for AI agent workflow automation.
