Ethereum MCP Server: Universal Integration for AI Applications

Overview: What is Ethereum MCP Server?

The Ethereum MCP Server is a robust, experimental implementation designed to provide a comprehensive set of features for Ethereum-based transactions and smart contract interactions. By leveraging FastAPI and Web3.py, it aims to facilitate seamless communication between AI applications and the Ethereum blockchain ecosystem. This server supports wallet management, transaction handling, smart contract interactions, and token operations—all aligned with Model Context Protocol (MCP) standards.

🔧 Core Features & MCP Capabilities

The Ethereum MCP Server is designed to bridge the gap between AI applications and decentralized Web3 technologies through a standardized protocol. Key features include:

Wallet Management

• Create and Import Wallets: Users can generate new wallets or import existing ones, ensuring flexibility in key management.
• List Managed Wallets: Easily view all associated wallets.
• Check ETH Balances & Secure Private Keys: Monitor balances and ensure private keys are handled securely.

Transaction Management

• Send Transactions: Facilitate the sending of ETH transactions with detailed parameters for customization.
• Transaction Details & Receipts: Retrieve comprehensive details about completed transactions, including gas usage and receipts.
• Gas Estimation & Nonce Management: Optimize transaction costs by accurately estimating gas requirements and managing nonce values.

Contract Interaction (Coming Soon)

• Deploy & Call Methods: AI applications can deploy custom smart contracts and interact with deployed ones through method calls and event listening.
• ABIs & ERC20/ERC721 Operations: Handle Advanced Business Logic (ABI) interactions, as well as ERC20 token balances, transfers, NFT metadata retrieval, and more.

Token Management (Coming Soon)

• ERC20 Interactions: Check balances, send tokens between accounts, and manage approval states.
• NFT Transfers & Metadata: Retrieve and transfer non-fungible tokens with ease.

Advanced Features

Although still under development, the server will support advanced features such as EIP-7702 delegation, event log retrieval, partial withdrawals, full withdrawals, and batch operations—all essential for sophisticated AI workflows.
