AI assistants like ChatGPT, Claude, and Cursor are rapidly reshaping how developers interact with software. Anthropic's new Model Context Protocol (MCP) is an open standard that solves the problem of exposing APIs to Large Language Models (LLMs) in a portable and predictable way. MCP is a lightweight, machine-readable specification that bridges the gap between traditional APIs and AI agents. It translates your API into a format that AI tools can understand and use, opening up the ability for anyone to use natural language to interact with your API. By standardizing this layer, MCP turns your API into an AI-native interface. Using MCP servers provides seamless AI integration, consistent, spec-driven behavior, secure and controlled access, and portable deployment. Developers can generate a ready-to-use MCP server from their OpenAPI spec using liblab in just a few minutes, making APIs usable by AI with no extra boilerplate.
