## Description

JSON Query MCP server provides tools for efficiently working with large JSON files through the Model Context Protocol. Developed by Michael Graczyk, this TypeScript implementation offers three key capabilities: querying JSON using JSONPath expressions, searching for keys similar to a query string, and finding values that match search criteria. The server is designed to help LLM models extract specific information from complex JSON structures without having to process the entire file, making it particularly valuable when working with large API specifications, configuration files, or data exports.
