mcp-etherscan

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

Part of Pipeworx — an MCP gateway connecting AI agents to 673+ 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.

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 673+ data sources:

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

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.
