What is Etherscan MCP Server?

This is an Etherscan API client implemented in Go language, specifically designed for the Model Context Protocol (MCP). It allows LLM (Large Language Model) applications to access data from over 50 blockchain networks through simple natural language queries.

How to use Etherscan MCP Server?

You can use it in two ways: 1) Directly integrate it into LLM applications in standard input/output mode; 2) Access it through an HTTP interface in SSE (Server - Sent Events) mode.

Use cases
