Blockscout Mcp Server

Wraps the Blockscout blockchain explorer API so Claude can query on-chain data across multiple chains. You get tools for address balances, token holdings, NFT inventories, transaction history with time range filtering, contract ABIs, and ENS resolution. The server handles pagination with opaque cursors and truncates large responses to avoid blowing through context windows. Useful when you need to analyze wallet activity, track token transfers, inspect verified contract source code, or pull historical transaction data for a specific time period. Supports both single-chain queries and multi-chain analysis through Blockscout's PRO API. Also ships with a REST wrapper if you want to call the tools outside MCP.
