Tool Categories

🔗 Core Ethereum

Network info • Block/transaction data • Wallet operations • Gas estimation • ENS resolution • Message signing • Unit conversion

🪙 Token Standards

ERC20: Token info, balances, transfers, approvals
ERC721: NFT info, ownership, transfers, metadata
ERC1155: Multi-token balances, transfers, batch operations

📝 Transaction Management

Transaction preparation • ERC20/721/1155 transaction prep • Secure transaction broadcasting • Gas optimization

🔧 Contract Interaction

Smart contract calls • Contract code inspection • Custom ABI support

Quick Example

# Get Vitalik's ETH balance
"getWalletBalance": {
  "address": "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045",
  "provider": "mainnet"
}

# Get USDC token info
"erc20GetTokenInfo": {
  "tokenAddress": "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48",
  "provider": "mainnet"
}

Installation

git clone https://github.com/yourusername/ethers-server.git
cd ethers-server
npm install
npm run build

Environment Variables

Create .env file:

ALCHEMY_API_KEY=your_alchemy_key
INFURA_API_KEY=your_infura_key
DEFAULT_NETWORK=mainnet

Advanced Setup

Local Project

claude mcp add --scope local ethers-wallet --env ALCHEMY_API_KEY=your_key -- node /path/to/build/src/index.js

Shared Team Config

claude mcp add --scope project ethers-wallet -- node /path/to/build/src/index.js

Security

🔐 Secure by Design: Uses prepare → sign → send workflow. Private keys never stored on server. External signing supported (hardware wallets, offline signing).

⚠️ API Keys: Protect your .env file. Never expose Alchemy/Infura keys.

Development

Built with ethers.js v6 for maximum compatibility and performance. Full TypeScript support with comprehensive error handling.

Testing: npm test (requires Hardhat local node)
Build: npm run build
