Architecture Overview

Major modules & flow:

1. CLI parses flags → starts HTTP server.
2. SSE endpoint initializes MCPServer via createMcpServer.
3. Parser loads / caches OpenAPI spec.
4. Auth tools & endpoint lazy registrations created.
5. Tool call executes handler pipeline → metrics + response.
6. Streaming events emitted when applicable.
