Blockscout MCP Server
Query blockchain data from any EVM chain using Blockscout's MCP server — access blocks, transactions, addresses, tokens, and smart contracts through AI assistants.
Overview
The Blockscout MCP Server enables AI assistants to query blockchain data from any EVM-compatible chain using Blockscout, the open-source block explorer. AI models can retrieve block details, transaction data, address information, token balances, and smart contract interactions — making on-chain data accessible through natural language conversations.
Open Source:
Developed by Blockscout. Supports any EVM chain with a Blockscout explorer instance.
Key Features
Block & Transaction Data
Query block details, transaction histories, and gas metrics across EVM chains.
Address Lookups
Retrieve address balances, transaction history, token holdings, and contract interactions.
Token & Balance Queries
Look up ERC-20 token balances, NFT holdings, and token transfer histories.
Smart Contract Verification
Access verified contract source code, ABI data, and contract-level interactions.
