Show HN: Transform your REST API into optimized MCP server in one command line

I built an open-source tool to turn any REST API into a GraphQL-like API with custom fields selection for every endpoint. Simply pass the OpenAPI specification and run one command line. Create a fieldflow-optimized MCP server so AI agents will only fetch the fields they need, reducing noise in context. It'll increase agent responses speed and improve response accuracy. Let me know what you think about this project! Hope that helps :)
