# Custom Context Transformer

> Use this tool when you need to transform unstructured text into structured JSON data, solving problems of data inconsistency and integration with downstream systems. It takes in customizable templates and unstructured text as input, and outputs structured JSON objects, making it ideal for applications that require processing AI-generated text into standardized data formats. The Custom Context Transformer is particularly useful when working with complex nested JSON structures and key-value pair extraction.

## Description

A TypeScript-based MCP server that transforms unstructured text into structured JSON data using customizable templates with placeholders. This implementation provides two main tools: 'group-text-by-json' which analyzes JSON templates to generate prompts that guide AI models in extracting key information, and 'text-to-json' which converts the AI-generated text into structured JSON objects based on the original template. The server supports complex nested JSON structures and intelligently extracts key-value pairs from text, making it ideal for applications that need to process AI outputs into structured data formats for downstream processing or integration with other systems.
