A Model Context Protocol (MCP) server for querying large JSON files. This server provides tools for working with large JSON data that can be used by LLM models implementing the Model Context Protocol. - Query JSON files using JSONPath expressions - Search for keys similar to a query string - Search for values similar to a query string Here is an example of the Cursor Agent using the tool to read a a very large (>1M character) JSON Swagger definition, and extracting a small portion to write a typescript interface.
