Etherscan
This MCP server provides blockchain data access through Etherscan's API V2, enabling AI assistants to query account balances, transaction details, block information, contract data, and gas prices across 50+ supported chains using a single API key. Built by WrldRelief using Go with the mark3labs/mcp-go library, it offers 19 specialized tools including multi-chain account balance retrieval, contract ABI and source code access, token balance queries, transaction history analysis, and gas oracle data, supporting both stdin/stdout and SSE server modes for flexible deployment. The implementation features comprehensive chain support from Ethereum and BSC to Layer 2 networks like Arbitrum and Polygon, robust error handling for API responses, and native token detection with proper symbol mapping, making it valuable for DeFi analysis workflows, blockchain data monitoring, portfolio tracking applications, and building AI assistants that need programmatic access to on-chain data without manual block explorer navigation.
