This MCP server lets Claude interact with Ethereum and other EVM-compatible blockchains through ethers.js, enabling you to create wallets, check balances, send transactions, and call smart contracts directly from Claude.

How to use

You can access Ethereum and EVM functionality through Claude by configuring the MCP server as a backend for Claude Desktop. Once connected, you can ask Claude to create wallets, check balances, send funds, call contract methods without sending transactions, sign messages, and inspect blocks, transactions, and on-chain data.

Practical usage patterns include creating a new wallet, querying balances, sending ether to another address, and interacting with smart contracts. You can also inspect gas prices, nonces, and transaction receipts, or sign messages and verify signed data for secure workflows.

How to install

Prerequisites you need before starting are your system with Node.js v16 or higher and access to Claude Desktop.

Option 1: Using npx (recommended) lets you run the MCP server without a local install. Use this command to start immediately.

npx @mcp-dockmaster/mcp-cryptowallet-evm

Option 2: Manual installation if you prefer to run locally. Follow these steps.

git clone https://github.com/dcSpark/mcp-cryptowallet-evm.git
cd mcp-cryptowallet-evm
npm ci
npm run build
