Ethereum MCP Server

The Ethereum MCP Server bridges AI assistants with the Ethereum blockchain, enabling secure wallet management, transaction orchestration, and smart‑contract interaction through a single, well‑structured MCP interface. It solves the common pain point of exposing blockchain operations to AI agents: developers can now let Claude or other assistants perform on‑chain actions without exposing private keys, managing gas, or dealing with low‑level Web3 details.

At its core, the server offers three main capabilities. First, it provides a robust wallet management API that allows agents to create new wallets, import existing ones, and query balances—all while keeping private keys encrypted in memory or secure storage. Second, the transaction management layer handles every step of an ETH transfer: from estimating gas and nonce to monitoring confirmations and retrieving receipts. Finally, the contract interaction module gives agents full control over smart contracts: deploying new bytecode with ABI, loading existing contracts, invoking state‑changing methods, reading view functions, and querying past events. These features are exposed through clear, JSON‑based MCP methods such as , , and .

Real‑world use cases abound. A finance bot could automatically rebalance a portfolio by reading token balances and sending ERC‑20 transfers, all orchestrated through MCP calls. A decentralized application support assistant might deploy a new contract for a user‑generated token, load it, and expose its functions to the front end. In testing environments, a QA engineer can spin up temporary wallets and run contract interactions in isolation, ensuring deterministic outcomes without touching production keys.

Integration into AI workflows is straightforward: an MCP‑aware assistant simply sends a JSON request to the server and receives structured responses. Because all operations are wrapped in a single protocol, developers can compose complex chains of actions—e.g., read a contract state, decide whether to trigger a transfer, and then log the transaction receipt—without writing custom code for each step. The server’s emphasis on secure key handling and gas estimation removes common pitfalls, allowing AI agents to act safely and efficiently on the Ethereum network.

What sets this server apart is its developer‑centric design. It abstracts away the intricacies of Web3.py while still exposing low‑level control when needed (e.g., custom gas prices or constructor arguments). The upcoming token and advanced features—such as EIP‑7702 delegation and batch operations—promise to extend its utility further, making it a versatile backbone for any AI‑driven blockchain application.
