# Blockscout MCP — multi-chain EVM explorer (3,000+ chains)

Open-source, self-hostable EVM explorer covering 3,000+ chains. Critical for bridge-tracing investigations that move funds across Polygon, Arbitrum, Optimism, BSC, and other EVM networks beyond Ethereum mainnet.

## Install

Remote MCP connector (recommended):

```
Add the Blockscout remote MCP endpoint in Claude Desktop settings.
See https://github.com/blockscout/mcp-server for the current endpoint URL.
```

Or self-host:

```
git clone https://github.com/blockscout/mcp-server
docker compose up
```

## Configuration

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

## What it adds

Etherscan (026) covers Ethereum mainnet. When funds move via a bridge to Polygon, Arbitrum, BSC, or any other EVM chain, Blockscout picks up the trail. Essential for the cross-chain bridge-tracing workflow where funds move through multiple networks to obscure origin.
