## Description

Etherscan MCP Server provides a bridge between AI assistants and the Etherscan API, enabling comprehensive access to Ethereum blockchain data. Built with TypeScript using FastMCP, it offers tools for querying account balances, transaction details, contract information, token data, gas metrics, and network statistics. The server handles API authentication through environment variables, formats responses consistently, and supports both stdio and HTTP/SSE transport modes. It's particularly valuable for blockchain developers, analysts, and users who need to access Ethereum data through natural language interfaces without managing the complexities of Etherscan's API directly.
