## Description

This MCP server generates and manages mock API servers from OpenAPI/Swagger specifications, creating fully functional FastAPI applications with Docker support, request logging, authentication middleware, webhook handling, and admin UIs. Built by Jascha Wanger/Tarnover LLC using Jinja2 templating and SQLite for persistence, it provides tools for generating mock servers with configurable features, discovering running mock instances, and analyzing request logs with performance metrics and error patterns. The implementation is valuable for API development teams who need realistic mock services for testing, integration work, or demonstrating API behavior before backend implementation is complete.
