etherscan

The etherscan v2 API MCP server enables developers to easily access and interact with the Etherscan API, which provides extensive data on Ethereum transactions, addresses, and tokens. By using this MCP server, you can streamline your application’s integration with Etherscan's services, retrieving real-time blockchain data to enhance your Ethereum-based projects. This server simplifies interactions with the API, allowing for efficient querying and data retrieval.

Once connected to the etherscan MCP server, you can issue queries to retrieve various types of blockchain data, such as transaction history, token balances, and account information. You can utilize parameters specific to the Etherscan API to tailor your requests, ensuring you get the exact data needed for your application. It’s recommended to familiarize yourself with the Etherscan API documentation to understand the available endpoints and how to craft your queries effectively.

Prerequisites

Before installing the etherscan MCP server, ensure you have Node.js installed on your system. You can download it from nodejs.org.

Option A: Quick start with npx

If you want a quick start without global installation, you can use npx. Run the following command in your terminal:

npx -y etherscan-mcp-server  

Option B: Global install alternative

To install the server globally, use the following command:

npm install -g etherscan-mcp-server  

After installation, you can start the server using the command:

etherscan-mcp-server  

When configuring the etherscan MCP server, ensure you have your Etherscan API key ready, as you'll need it to authenticate requests. Set the API key as an environment variable named ETHERSCAN_API_KEY to avoid hardcoding sensitive information. Common issues may arise from rate limits imposed by the Etherscan API, so consider implementing error handling for 429 status codes in your application.
