API Examples

Get token balance using ENS name
// Example: Get token balance using MCP client
const mcp = new McpClient("http://localhost:3000");

const result = await mcp.invokeTool("get-token-balance", {
  tokenAddress: "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48", // USDC on Ethereum
  ownerAddress: "vitalik.eth", // ENS name instead of address
  network: "ethereum"
});

console.log(result);
// {
//   tokenAddress: "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48",
//   owner: "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045",
//   network: "ethereum",
//   raw: "1000000000",
//   formatted: "1000",
//   symbol: "USDC",
//   decimals: 6
// }
Resolve ENS name to address
// Example: Resolve ENS name using MCP client
const mcp = new McpClient("http://localhost:3000");

const result = await mcp.invokeTool("resolve-ens", {
  ensName: "vitalik.eth",
  network: "ethereum"
});

console.log(result);
// {
//   ensName: "vitalik.eth",
//   normalizedName: "vitalik.eth",
//   resolvedAddress: "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045",
//   network: "ethereum"
// }
Check if address is a contract
// Example: Check if address is a contract
const mcp = new McpClient("http://localhost:3000");

const result = await mcp.invokeTool("is-contract", {
  address: "0x6B175474E89094C44Da98b954EedeAC495271d0F", // DAI token
  network: "ethereum"
});

console.log(result);
// {
//   address: "0x6B175474E89094C44Da98b954EedeAC495271d0F",
//   isContract: true,
//   network: "ethereum"
// }
