What if you could describe an API in plain English and your AI assistant would design the interface, validate it, and generate a production-ready SDK — all without leaving your editor?

That's exactly what happens when you connect ApiGear to your AI coding assistant via MCP. No spec syntax to learn, no CLI commands to memorize. You describe what you need, and your assistant handles the rest — from API design to generated code.

An API surface is the public interface of an object which is exposed to users of the object. The API surface is defined by an IDL and defines the contract between the user and the implementer of an object.
