Stop Converting OpenAPI Specs Into MCP Servers

Many developers are auto-converting OpenAPI specs into MCP servers, and running straight into trouble. MCP isn’t about dumping every REST endpoint into an agent; it’s about giving agents high-level, reliable capabilities. In this talk, I’ll show why naive conversions fail, what happens when your agent has too many tools, and how to redesign MCP servers the right way. You’ll learn practical patterns for collapsing complex workflows into clean, deterministic actions and how to think “agent-first” instead of “API-first” when building tools for the next generation of AI systems.
