Claude Integration

Connect y0 to Claude in under 2 minutes — no coding required.

Add Connector (Recommended)

Works on Claude Desktop, claude.ai, and Claude Mobile (iOS / Android).

Get your API key at app.y0.exchange → API Keys
Open Claude → Settings → Connectors → Add custom connector
Name: y0
URL: https://mcp.y0.exchange/mcp?key=YOUR_API_KEY
Save — y0 tools are now available in all your conversations

That’s it. No installs, no config files, no terminal.

Your API key is passed securely via HTTPS. It identifies your wallet so the AI agent knows your address and permissions automatically.

Verify

After adding the connector, start a new conversation and try asking:

“What is the ETH balance of vitalik.eth (0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045)?”

Claude will use the get_balance tool and show you the result.

Example Prompts

Read Operations

“Show me the portfolio for 0xd8dA…”
“What’s the current price of ETH and ARB?”
“Get a quote: swap 1000 USDC to ETH on Arbitrum”
“What’s the gas price on Base right now?”
“Show recent swaps for 0xd8dA… on Ethereum”

Write Operations (requires API key)

“Swap 100 USDC to ETH on Ethereum”
“Send 0.5 ETH to 0x1234… on Arbitrum”

Advanced: Local MCP Server

If you prefer running the MCP server locally (e.g. for development or offline use), you can configure it via the config file.

Prerequisites

Claude Desktop installed
Node.js 20+ installed

Configuration

Open Claude Desktop settings
Go to Developer > Edit Config
Add the y0 MCP server:

{
  "mcpServers": {
    "y0": {
      "command": "npx",
      "args": ["-y", "@y0exchange/mcp"],
      "env": {
        "Y0_API_KEY": "y0_your_api_key_here"
      }
    }
  }
}

Restart Claude Desktop
