Features

🔌

Full AgentKit via MCP Protocol

Exposes the complete Coinbase AgentKit toolset as MCP tools, making all on-chain capabilities available to Claude and other MCP clients without writing any SDK code. Add to claude_desktop_config.json and you're done.

👛

Wallet Create / Send / Balance

Core wallet operations available as discrete MCP tools: create a new wallet, check ETH/ERC-20 balances, send tokens, and receive payment addresses. Claude can call these tools conversationally without any additional configuration.

🏦

DeFi Interactions

Swap tokens on DEXes, interact with DeFi protocols, deploy smart contracts, and call arbitrary contract functions — all via MCP tool calls. Enables Claude to autonomously execute on-chain strategies when instructed.

🖥️

Works with Claude Desktop and Claude Code

Drop the MCP server config into Claude Desktop's configuration file and wallet tools appear automatically in every conversation. Also compatible with Claude Code via the MCP server configuration, enabling agentic coding with on-chain capabilities.

Integration

// Add to ~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "coinbase-agentkit": {
      "command": "npx",
      "args": ["-y", "@coinbase/agentkit-mcp"],
      "env": {
        "CDP_API_KEY_NAME":       "your-cdp-api-key-name",
        "CDP_API_KEY_PRIVATE_KEY": "your-cdp-private-key",
        "NETWORK_ID":             "base-mainnet"
      }
    }
  }
}

// Claude can now use tools like:
// - create_wallet      → provision a new CDP wallet
// - get_balance        → check ETH / ERC-20 balances
// - transfer           → send tokens to an address
// - trade              → swap tokens via DEX
// - deploy_contract    → deploy a smart contract
// - invoke_contract    → call any contract function

// Example prompt to Claude:
// "Check my wallet balance on Base and send 10 USDC to 0xABC..."
