mcp-etherscan

Etherscan MCP — multichain block-explorer API (Etherscan V2)

Part of Pipeworx — an MCP gateway connecting AI agents to 250+ live data sources.

Tools

| Tool | Description | |------|-------------| | get_token_balance | ERC-20 token balance for an address against a specific token contract. | | get_contract_abi | Verified contract ABI as JSON (if the contract is verified on Etherscan). | | get_contract_source | Verified contract source code, compiler version, optimization settings, and license. |

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "etherscan": {
      "url": "https://gateway.pipeworx.io/etherscan/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 250+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about Etherscan data" })

The gateway picks the right tool and fills the arguments automatically.
