🚀 Quick Start

Basic Setup

import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp.js"
import { Client } from "@modelcontextprotocol/sdk/client/index.js"

// Construct server URL with authentication
const url = new URL("https://server.smithery.ai/@cuongpo/hyperion-mcp-server/mcp")
url.searchParams.set("api_key", "36e96d01-a9dd-4e4c-a705-bbe239a712ea")
url.searchParams.set("profile", "notable-sparrow-IsrW6Y")
const serverUrl = url.toString()

const transport = new StreamableHTTPClientTransport(serverUrl)

// Create MCP client
const client = new Client({
  name: "My Hyperion App",
  version: "1.0.0"
})

await client.connect(transport)

// List available tools
const tools = await client.listTools()
console.log(`Available tools: ${tools.map(t => t.name).join(", ")}`)

📦 Installation

    // Deploy an ERC721 contract
    // Note: You need to compile the contract first and get the bytecode
    const deployment = await client.callTool('deploy_erc721_token', {
      name: 'My Art Collection',
      symbol: 'ART',
      bytecode: '0x608060405234801561001057600080fd5b50...' // Your compiled bytecode

  // ... setup client as above ...

  const contractAddress = '0x1234567890123456789012345678901234567890'

    })
    console.log('Transaction Result:', transaction.content[0].text)

  } catch (error) {
    console.error('Contract interaction error:', error)
  }

⚠️ Error Handling

Common Error Types

async function handleErrors() {
  try {
    const result = await client.callTool('send_transaction', {
      to: '0x742d35Cc6634C0532925a3b8D4C9db96C4b4d4d4',
      amount: '1000'
    })
  } catch (error) {
    if (error.message.includes('insufficient funds')) {
      console.error('Not enough balance for transaction')
    } else if (error.message.includes('invalid address')) {
      console.error('Invalid recipient address')
    } else if (error.message.includes('gas')) {
      console.error('Gas estimation failed or gas limit too low')
    } else {
      console.error('Unknown error:', error.message)
    }
  }
}

Retry Logic

async function withRetry(operation, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      return await operation()
    } catch (error) {
      if (i === maxRetries - 1) throw error
      console.log(`Attempt ${i + 1} failed, retrying...`)
      await new Promise(resolve => setTimeout(resolve, 1000 * (i + 1)))
    }
  }
}

// Usage
const result = await withRetry(() =>
  client.callTool('get_balance', {
    address: '0x742d35Cc6634C0532925a3b8D4C9db96C4b4d4d4'
  })
)

🎯 Best Practices

1. Connection Management

class HyperionClient {
  constructor(apiKey, profile) {
    this.apiKey = apiKey
    this.profile = profile
    this.client = null
  }

  async connect() {
    if (this.client) return this.client

    const url = new URL("https://server.smithery.ai/@cuongpo/hyperion-mcp-server/mcp")
    url.searchParams.set("api_key", this.apiKey)
    url.searchParams.set("profile", this.profile)

    const transport = new StreamableHTTPClientTransport(url.toString())
    this.client = new Client({
      name: "Hyperion App",
      version: "1.0.0"
    })

    await this.client.connect(transport)
    return this.client
  }

  async disconnect() {
    if (this.client) {
      await this.client.close()
      this.client = null
    }
  }
}

2. Environment Configuration

// config.js
export const config = {
  smithery: {
    apiKey: process.env.SMITHERY_API_KEY || "36e96d01-a9dd-4e4c-a705-bbe239a712ea",
    profile: process.env.SMITHERY_PROFILE || "notable-sparrow-IsrW6Y"
  },
  hyperion: {
    testnet: {
      rpcUrl: "https://hyperion-testnet.metisdevops.link",
      chainId: 133717,
      explorerUrl: "https://hyperion-testnet-explorer.metisdevops.link"
    }
  }
}

3. Type Safety (TypeScript)

interface WalletInfo {
  address: string
  mnemonic?: string
  name?: string
}

interface TransactionResult {
  hash: string
  status: 'pending' | 'confirmed' | 'failed'
  explorerUrl?: string
}

interface TokenInfo {
  name: string
  symbol: string
  decimals: number
  totalSupply: string
  address: string
}

class TypedHyperionClient {
  async createWallet(name?: string): Promise<WalletInfo> {
    const result = await this.client.callTool('create_wallet', { name })
    // Parse and return typed result
    return this.parseWalletResult(result)
  }

  async sendTransaction(
    to: string,
    amount: string,
    tokenAddress?: string
  ): Promise<TransactionResult> {
    const result = await this.client.callTool('send_transaction', {
      to,
      amount,
      tokenAddress
    })
    return this.parseTransactionResult(result)
  }
}

4. Gas Optimization

async function optimizeGas() {
  // Always estimate gas before sending transactions
  const gasEstimate = await client.callTool('estimate_gas', {
    to: '0x742d35Cc6634C0532925a3b8D4C9db96C4b4d4d4',
    value: '1.0'
  })

  // Add 20% buffer to gas estimate
  const gasLimit = Math.floor(parseInt(gasEstimate.gasUsed) * 1.2).toString()

  // Send transaction with optimized gas
  const result = await client.callTool('send_transaction', {
    to: '0x742d35Cc6634C0532925a3b8D4C9db96C4b4d4d4',
    amount: '1.0',
    gasLimit: gasLimit
  })
}

5. Batch Operations

async function batchOperations() {
  const addresses = [
    '0x742d35Cc6634C0532925a3b8D4C9db96C4b4d4d4',
    '0x123d35Cc6634C0532925a3b8D4C9db96C4b4d123',
    '0x456d35Cc6634C0532925a3b8D4C9db96C4b4d456'
  ]

  // Check multiple balances concurrently
  const balancePromises = addresses.map(address =>
    client.callTool('get_balance', { address })
  )

  const balances = await Promise.all(balancePromises)
  balances.forEach((balance, index) => {
    console.log(`Address ${addresses[index]}: ${balance.content[0].text}`)
  })
}

🔒 Security Considerations

1. API Key Management

// ❌ DON'T: Hardcode API keys
const apiKey = "36e96d01-a9dd-4e4c-a705-bbe239a712ea"

// ✅ DO: Use environment variables
const apiKey = process.env.SMITHERY_API_KEY

// ✅ DO: Use secure key management
import { getSecret } from './secure-config.js'
const apiKey = await getSecret('SMITHERY_API_KEY')

2. Input Validation

function validateAddress(address) {
  if (!address || typeof address !== 'string') {
    throw new Error('Address is required and must be a string')
  }
  if (!/^0x[a-fA-F0-9]{40}$/.test(address)) {
    throw new Error('Invalid Ethereum address format')
  }
  return address.toLowerCase()
}

function validateAmount(amount) {
  if (!amount || isNaN(parseFloat(amount))) {
    throw new Error('Amount must be a valid number')
  }
  if (parseFloat(amount) <= 0) {
    throw new Error('Amount must be greater than 0')
  }
  return amount
}

3. Rate Limiting

class RateLimiter {
  constructor(maxRequests = 10, windowMs = 60000) {
    this.maxRequests = maxRequests
    this.windowMs = windowMs
    this.requests = []
  }

  async checkLimit() {
    const now = Date.now()
    this.requests = this.requests.filter(time => now - time < this.windowMs)

    if (this.requests.length >= this.maxRequests) {
      const oldestRequest = Math.min(...this.requests)
      const waitTime = this.windowMs - (now - oldestRequest)
      await new Promise(resolve => setTimeout(resolve, waitTime))
    }

    this.requests.push(now)
  }
}

const rateLimiter = new RateLimiter()

async function rateLimitedCall(toolName, params) {
  await rateLimiter.checkLimit()
  return await client.callTool(toolName, params)
}
