Ethereum MCP Server

Example Use Cases

• 1

  Fetch an address's ETH balance and recent transaction history to reason about account activity.

  Up-to-date ETH price and gas estimates to compute fiat values and estimate transaction costs.

• 3

  Detailed transaction and latest block information to validate on-chain events or cross-check model outputs.

Description

This repository implements a Model Context Protocol (MCP) server that provides Ethereum-specific tools and resources so agents can query real-time chain data and perform common on-chain lookups. It integrates Ethereum JSON-RPC (via LlamaRPC), CoinGecko for ETH price, and Etherscan for transaction history, and exposes functions like get_eth_balance, get_eth_price, get_gas_price, get_latest_block, get_transaction, estimate_tx_fee, and get_account_transactions. The server is intended for easy integration into agent platforms (examples given for Cursor) and requires an Etherscan API key where noted.
