## Description

The REI Crypto MCP Server provides AI assistants with access to professional cryptocurrency data APIs through a unified interface. Built by the Rei Network, this implementation connects to DefiLlama Pro, CoinGecko Pro, and Arkham Intelligence APIs, offering tools for querying token prices, market data, blockchain analytics, and on-chain intelligence. The server exposes a comprehensive set of endpoints for tracking DeFi protocols, monitoring token performance, analyzing wallet activities, and accessing historical price data.
