## Description

This MCP server provides AI assistants with comprehensive blockchain data access through Tatum's API infrastructure, built by the Tatum team using TypeScript with axios for HTTP requests and the Model Context Protocol SDK. The implementation offers 13 tools across two main categories: gateway tools for executing RPC calls across 130+ blockchain networks including Bitcoin, Ethereum, Polygon, and Solana through Tatum's gateway infrastructure, and data tools for retrieving NFT metadata, wallet portfolios, transaction histories, token ownership verification, and exchange rates. Built with robust error handling, caching mechanisms for blockchain data, and support for both JSON-RPC and REST API calls depending on the blockchain protocol, it serves developers building blockchain applications who need natural language access to multi-chain data, financial analysis workflows requiring real-time cryptocurrency information, and AI-powered tools that need to interact with decentralized networks without managing multiple blockchain node connections.
