You can write your own check that can decorate the command

def is_any_user(ids):
    def predicate(ctx):
        return ctx.message.author.id in ids
    return commands.check(predicate)

LIST_OF_ADMINS = ['3557657657647676', '36567565756766767', '343657687786435432']

@bot.command(pass_context=True)
@is_any_user(LIST_OF_ADMINS)
async def hello(ctx):
     await bot.say("Hello {}".format(ctx.message.author.mention))
