Your First Tool

This guide walks you through using your first Universal Crypto MCP tool.

Prerequisites

Step 1: Start the Server

Make sure the MCP server is configured in your client. For Claude Desktop:

{
  "mcpServers": {
    "universal-crypto": {
      "command": "npx",
      "args": ["@nirholas/universal-crypto-mcp"]
    }
  }
}

Restart Claude Desktop after updating the config.

Step 2: Check Available Tools

Ask Claude to list available tools:

"What crypto tools do you have available?"

Claude will show you the 380+ tools organized by category: - Market Data - Trading - DeFi - Wallets - Payments - And more...

Step 3: Get a Price

Let's start with a simple price check:

"What's the current price of Bitcoin?"

Claude will use the get_price tool to fetch real-time data:

🪙 Bitcoin (BTC)
💰 Price: $67,234.56
📈 24h Change: +2.3%
📊 Market Cap: $1.32T
💹 Volume: $28.5B

"What coins are trending right now?"

Claude will use the get_trending tool:

🔥 Trending Coins

1. PEPE - $0.00001234 (+45%)
2. WIF - $2.34 (+23%)
3. BONK - $0.00003456 (+18%)
...

Step 5: Portfolio Check (with wallet)

If you've configured a wallet, check your portfolio:

"Show my portfolio across all chains"

Claude will scan your wallet across supported chains:

📊 Portfolio Summary

Ethereum:
  • 0.5 ETH ($1,234.56)
  • 1,000 USDC ($1,000.00)

Arbitrum:
  • 0.1 ETH ($246.91)
  • 500 USDC ($500.00)

Total: $2,981.47

Step 6: Token Security Check

Before buying any token, check its safety:

"Is this token safe: 0x1234...?"

Claude will use security tools:
