Etherscan launched its « Build with AI » suite in late August 2026, giving AI agents and coding assistants like Claude and ChatGPT direct access to on-chain data across more than 60 EVM-compatible chains. The core tool is a Model Context Protocol (MCP) server accessible at mcp.etherscan.io/mcp, offering around 20 functions covering essential blockchain operations: balance queries, transaction lookups, token transfer histories, contract details, and gas prices.

This infrastructure aims to combat the problem of data hallucination in AI models by grounding agents in verified blockchain data.
