Here's a dirty secret about LLMs: the more JSON you feed them, the dumber they get. But what if there was a tool that got smarter with more data?

quicktype MCP is a Model Context Protocol server that solves this fundamental problem. Give your coding agent the ability to understand JSON as humans do—by inferring its high-level shape and purpose.

Given JSON and a target language, quicktype infers the data's types, and returns type definitions (e.g. schema, classes, structs, interfaces) and serializers in the target language. It does this by understanding the high-level shape and purpose of the data, just like a human would.

quicktype has written billions of lines of code that better understand data, and can help your agent do the same. The MCP server makes quicktype's capabilities available to AI coding assistants like Claude and Cursor, enabling them to work with JSON data more intelligently.
