Blockscout

This MCP server provides blockchain data access through Blockscout APIs, enabling AI assistants to query comprehensive blockchain information including address balances, token holdings, NFT collections, transaction details, smart contract ABIs, and ENS name resolution across multiple blockchain networks. Built by Blockscout, it dynamically resolves chain-specific API endpoints through Chainscout integration, supports caching for performance optimization, and includes specialized tools for transaction analysis with decoded parameters, event logs with smart contract metadata, and DeFi operation tracking. The implementation is particularly valuable for blockchain analysis, wallet auditing, smart contract debugging, and DeFi research workflows where AI assistants need enriched blockchain data beyond standard RPC calls.
