Sadly MyAnimeList discontinued their API, you might want to use an alternative API

MyAnimeList Client

For now you can:

Installation

Add this line to your application's Gemfile:

gem 'myanimelist_client'

And then execute:

$ bundle

Or install it yourself as:

$ gem install myanimelist_client

Overview

require 'myanimelist_client'

# First, create a client
# MyAnimeList.net requires a valid account to consume their API
client = MyanimelistClient.new 'username', 'password'

# Then you may want to check if your username / password are ok
if client.verify_credentials.ok?

  # Now you can use the API
  # Let's search a good anime!
  results = client.search_anime 'K-On'

  # Everything is nicely wrapped in small objects
  results.sort_by(&:score).reverse!.each do |anime|
    puts "#{anime.title} (#{anime.english}) - #{anime.score}"
  end

end

Nice, isn't it?

Usage

The Client

The client memorizes your username and password (myanimelist.net requires a valid account in order to consume their API) then it allows you to use the API:

client = MyanimelistClient.new('username', 'password')

Verify Credentials

Check your username / password with #verify_credentials:

user = client.verify_credentials # => MyanimelistClient::UserResponse

user.ok?                         # true when everything went right
user.error?                      # true when an error occured
user.raw                         # the raw response from the API or the error message

Search anime with #search_anime:

results = client.search_anime('anime name')

Thanks to harveyico for his myanimelist gem, it helped me (I was using it before and its code kinda influenced me).
