Tools

Usage

Once configured, ask your AI assistant:

• "Create a wallet on Sepolia with my key 0x... and Pimlico key pim_..."

• "Send 0.01 ETH to 0xABC..."

• "What's my wallet balance?"

• "Swap 0.1 ETH for USDC"

• "Freeze my wallet immediately"

The create_wallet tool must be called first to initialize the wallet before using any other tool.

Programmatic Usage

import { createBarzMcpServer } from '@barzkit/mcp'
import { StdioServerTransport } from '@modelcontextprotocol/sdk/server/stdio.js'

const server = createBarzMcpServer()
const transport = new StdioServerTransport()
await server.connect(transport)

Prerequisites

• Node.js >= 18
