Wraps the Blockscout blockchain explorer API to let Claude query addresses, contracts, transactions, and NFTs across multiple chains. You get balance lookups, token holdings with market data, transaction history with time range filters, contract ABIs and source code for verified contracts, and ENS resolution. The server handles pagination with opaque cursors and truncates large responses to keep token usage reasonable. Reach for this when you need to analyze on-chain data without bouncing between block explorers or writing custom RPC calls. Works through both the hosted endpoint at mcp.blockscout.com and a REST API wrapper if you need programmatic access outside MCP hosts.
