# Stellar XDR-JSON

> Use this tool when you need to decode and analyze Stellar blockchain data, converting XDR format to human-readable JSON to simplify transaction and contract event analysis. It solves problems of manual decoding and interpretation of complex binary data, making it ideal for blockchain developers and analysts. The tool takes XDR data as input and outputs JSON, providing a user-friendly interface for guessing XDR types, decoding arbitrary XDR data, and decoding Stellar transactions.

## Description

Stellar MCP Server for XDR-JSON provides Claude with tools to decode and understand Stellar blockchain data by converting XDR (External Data Representation) format to human-readable JSON. The server exposes three main tools: guessing XDR types, decoding arbitrary XDR data, and specifically decoding Stellar transactions. Built using the Model Context Protocol SDK and Stellar's XDR-JSON library, this implementation enables Claude to analyze blockchain transactions and contract events without requiring users to manually decode complex binary data, making it valuable for blockchain developers and analysts working with the Stellar network.
