Etherscan’s MCP (Model Context Protocol) allows you to connect Etherscan and 60+ supported chain data to your AI models such as ChatGPT, Claude. An ELI5, the MCP standard provides a list of tools that your model can call to lookup information via the Etherscan API. Yes, it is an API wrapper. This avoids common problem of LLMs making things up (hallucination) or getting blocked by captcha on a web search. Some use cases of our beta users
  • Comparing Solidity code with actual contracts deployed on chain
  • Customer support for bridge transactions, if the transactions has arrived
  • Portfolio management agents
