Ethereum Wallet API with network management, contract interaction, ENS, and token tools via MCP protocol
The MCP Ethers Wallet is an advanced MCP server designed to provide comprehensive Ethereum wallet and blockchain functionality to Model Context Protocol (MCP) clients, such as Claude Desktop. This server leverages ethers.js v6, a powerful JavaScript library, to deliver robust features like network configuration, wallet management, transaction execution, and interaction with various smart contracts. By adhering closely to the MCP specification, this server ensures seamless integration across multiple AI tools and applications, making it an essential component in any environment that requires Ethereum-related services.
The MCP Ethers Wallet MCP Server supports a wide array of core features that cater to both developers and end-users:
Network Management: The server provides detailed information about various Ethereum networks, including mainnet, testnets, and other supported chains like Polygon, Optimism, and Arbitrum. It allows users to manage their connections and switch between different environments as needed.
Wallet Creation & Management: Users can easily generate new wallets or load existing ones using a private key. The server manages wallet storage securely, offering methods for checking wallet existence, retrieving balances, sending transactions, and signing messages.
Transaction Execution: Comprehensive tools are provided to execute transactions of various types, including token transfers, contract interactions (ERC20, ERC721, ERC1155), and more. Real-world scenarios such as minting NFTs or transferring tokens between accounts can be seamlessly executed through this server.
ENS Resolution & Unit Conversion: Users benefit from ENS resolution capabilities to interact with Ethereum Name Service names and convert units efficiently within the blockchain ecosystem.
Advanced Gas Estimation & Transaction History: Efficient gas estimation ensures cost-effective transaction execution, while a robust history tracking system allows users to review past actions conveniently.
The architecture of the MCP Ethers Wallet is designed with flexibility and performance in mind. It adheres rigorously to the Model Context Protocol (MCP) specification, ensuring compatibility across multiple devices and applications. The backend codebase is built using TypeScript, ensuring reliability and ease of maintenance.
