This JSON MCP server implements a JSON Model Context Protocol (MCP) server for querying and manipulating JSON data. It exposes two tools: query and filter. The query tool accepts url and jsonPath, while the filter tool accepts url, jsonPath, and condition. The server uses JSONPath expressions augmented with a broad set of operations across arrays, strings, numbers, dates, and aggregations. Supported operations include array slicing, sorting, distinct, map, flatten, union, and intersection; string case conversion, prefix/suffix tests, contains and matches; numeric math, rounding, absolute values, and common functions like abs() and sqrt(); date formatting, isToday checks, and adding time units such as days, months, and years. Aggregation supports groupBy and calculations like sum, avg, min, and max. The README documents input shapes, usage patterns, and notes (e.g., JSONPath expressions start with $, array indices are zero-based, and string literals must be quoted). It also provides configuration guidance for Claude Desktop and direct node usage, plus development steps to build from source. This server is designed for MCP workflows, enabling LLMs to reason over JSON data through standardized tools.
