Blockscout MCP Server

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.

Key Features

Installation

{
  "mcpServers": {
    "blockscout": {
      "command": "npx",
      "args": [
        "-y",
        "@blockscout/mcp-server"
      ],

      }
    }
  }
}

Common Use Cases

• On-Chain Research: Query transaction histories and wallet activities for blockchain analysis
• Token Analysis: Look up token balances, transfers, and holder information across chains
• Contract Verification: Access verified smart contract source code and ABIs for development
• Blockchain Monitoring: Track blocks, gas prices, and network activity through AI conversations

When to Use This Server

Blockscout's MCP server is the fastest way to give an assistant on-chain data without running a node or writing RPC calls. Any EVM chain that exposes a Blockscout explorer is reachable through one config:

• Wallet & token research — "What tokens does this address hold?" or "show the last 20 transactions" become natural-language queries instead of multi-line RPC calls.
• Contract development — Pull verified source code and ABIs for a contract you're integrating against, so the assistant builds against the real interface.
• On-chain monitoring — Track blocks, gas prices, and network activity for a chain you operate on, all from a chat session.

For lower-level EVM access (raw JSON-RPC, eth_getLogs, etc.) see Ethereum RPC Blockchain MCP; for wallet interaction and signing, see Thirdweb MCP.
