This MCP Etherscan server provides Ethereum blockchain data tools via Etherscan's API. Built with TypeScript and leveraging the ethers.js library, it offers features like balance checking, transaction history viewing, token transfer tracking, contract ABI fetching, gas price monitoring, and ENS name resolution. The server is designed to run on stdio, making it compatible with MCP clients like Claude Desktop. By abstracting Etherscan API interactions into standardized MCP tools, it enables AI systems to easily access and analyze Ethereum blockchain data. This implementation is particularly useful for applications requiring real-time Ethereum data, such as DeFi analytics, wallet monitoring, or smart contract development assistance.
