### Description (declared)

# 🚀 Crypto MCP Server
## 📌 Overview

Crypto MCP Server is a Model Context Protocol (MCP) compatible server that provides real-time and historical cryptocurrency market data using ccxt.
It exposes three fully tested tools:

get_ticker → Live price & market summary

get_ohclv → Historical candlestick data

stream_ticker → Real-time price streaming (async generator)

The project includes:

Custom error handling

In-memory caching

A lightweight MCP server architecture

Complete test suite (pytest)

Local client for manual testing

## ✨ Features
🔹 get_ticker

Fetches:

last price

high & low

base volume

price_change_percent

🔹 get_ohclv

Fetches OHLCV candles with:

timestamp

open

high

low

close

volume

🔹 stream_ticker

Real-time streaming ticker with async generator that yields updates every N seconds.
