Implementation Reference

• src/tools/balance.ts:6-18 (handler)

  The check_balance tool is registered and implemented within the server.tool call. The handler logic calls the client.authGet("/v1/balance") method.

  server.tool(
  	"check_balance",
  	"Check your pre-funded USDC balance on the402.ai. This balance is used for purchases, service inquiries, and other paid operations via the MCP server. Requires API key.",
  	{},
  	async () => {
  		const result = await client.authGet("/v1/balance");
  		return {
  			content: [
  				{ type: "text" as const, text: JSON.stringify(result, null, 2) },
  			],
  		};
  	}
  );
