# MCP Etherscan Server
以下摘录自该仓库的 README（片段） · 在 GitHub 读完整 README →
An MCP (Model Context Protocol) server that provides Ethereum blockchain data tools via Etherscan's API. Features include checking ETH balances, viewing transaction history, tracking ERC20 transfers, fetching contract ABIs, monitoring gas prices, and resolving ENS names.
## Features
Balance Checking: Get ETH balance for any Ethereum address
Transaction History: View recent transactions with detailed information
Token Transfers: Track ERC20 token transfers with token details
Contract ABI: Fetch smart contract ABIs for development
Gas Prices: Monitor current gas prices (Safe Low, Standard, Fast)
ENS Resolution: Resolve Ethereum addresses to ENS names
## Prerequisites
Node.js >= 18
An Etherscan API key (get one at https://etherscan.io/apis)
## Installation
1. Clone the repository:
bash
git clone [your-repo-url]
cd mcp-etherscan-server
2. Install dependencies:
bash
npm install
3. Create a .env file in the root directory:
bash
ETHERSCANAPIKEY=yourapikeyhere
4. Build the project:
bash
npm run build
## Running the Server
Start the server:
bash
npm start
The server will run on stdio, making it compatible with MCP clients like Claude Desktop.
## How It Works
This server implements the Model Context Protocol (MCP) to provide tools for interacting with Ethereum blockchain data through Etherscan's API. Each tool is exposed as an MCP endpoint that can be called by compatible clients.
### Available Tools
1. check-balance
Input: Ethereum address
Output: ETH balance in both Wei and ETH
2. get-transactions
Input: Ethereum address, optional limit
Output: Recent transactions with timestamps, values, and addresses
3. get-token-transfers
Input: Ethereum address, optional limit
Output: Recent ERC20 token transfers with token details
4. get-contract-abi
Input: Contract address
Output: Contract ABI in JSON format
5. get-gas-prices
Input: None
Output: Current gas prices in Gwei
6. get-ens-name
Input: Ethereum address
Output: Associated ENS name if available
## Using with Claude Desktop
To add this server to Claude Desktop:
1. Start the server using npm start
2. In Claude Desktop:
Go to Settings
Navigate to the MCP Servers section
Click "Add Server"
Enter the following configuration:
json
"name": "Etherscan Tools",
"transport": "stdio",
"command": "node /path/to/mcp-etherscan-server/build/index.js"
Save the configuration
