what's Ethereum MCP?

Ethereum MCP is an open-source Model Context Protocol (MCP) server that enables AI agents and large language models, such as Claude or Codex, to interact with Ethereum and over 60 other blockchains using plain English queries. It aggregates data from multiple sources including Etherscan for balances and transactions, DefiLlama for TVL and yields, CoinGecko for prices, Blobscan for blobs, and more, providing 150+ tools for onchain research without context-switching or glue code. Users install via one-liner scripts for Claude Desktop/Code or configure RPC nodes for self-hosting, requiring only a free Etherscan API key.

Ethereum MCP enables plain English queries of live Ethereum/L2 data via Claude.
