# JSON Skeleton

> Use this tool when you need to simplify large JSON files and understand their structure without processing massive payloads. It creates lightweight representations by truncating strings, deduplicating arrays, and optionally showing only data types, making it ideal for analyzing API responses or data schemas. The JSON Skeleton server provides configurable outputs, including string truncation lengths and a type-only mode, to help developers quickly grasp data structures.

## Description

The JSON Skeleton MCP Server creates lightweight "skeleton" representations of large JSON files by truncating string values, deduplicating array items based on their structure, and optionally showing only data types instead of values. It intelligently preserves the complete JSON structure while dramatically reducing file size, making it particularly useful for understanding API responses or data schemas that exceed AI model context limits. The server offers configurable string truncation lengths and a ultra-compact type-only mode that replaces all values with their type names (str, int, bool, etc.), enabling developers to quickly grasp data structure without processing massive payloads.
