Overview
What is MCP Etherscan Server?
MCP Etherscan Server is an MCP (Model Context Protocol) server that provides Ethereum blockchain data tools via Etherscan's API. It is designed for developers and users who need to query on-chain information such as ETH balances, transaction history, ERC20 transfers, contract ABIs, gas prices, and ENS names through MCP-compatible clients like Claude Desktop.
How to use MCP Etherscan Server?
Install Node.js >=18, obtain an Etherscan API key from https://etherscan.io/apis, clone the repository, run npm install, create a .env file with ETHERSCAN_API_KEY=your_key, then build with npm run build and start with npm start. The server runs on stdio and can be added to Claude Desktop by configuring a new MCP server with the command node /path/to/build/index.js.
