Etherscan Opens Onchain Data API to AI Agents Across 60+ EVM Chains
Etherscan has released a suite of tools allowing AI agents and coding assistants to pull live blockchain data directly from its API. The release, called 'Build with AI', aims at developers building agents that need verified onchain facts across more than 60 EVM-compatible networks.
The tools include a Model Context Protocol (MCP) server, a hosted interface for plain language calls; a command-line tool for terminals, scripts, and CI pipelines; and a set of installable agent 'skills'. The MCP server exposes 20 tools, covering the basics of reading a chain, such as native and token balances, transaction lookups, and event logs.
Etherscan's release is seen as a solution to the 'hallucination problem' in crypto-AI tools. Language models can fabricate data when they do not have the right information, leading to costly mistakes. The release also warns users against pasting their API keys into fake MCPs posing as legitimate.
