AI编程助手服务器

export OPENROUTER_API_KEY="your_api_key_here"

ruby ./server.rb

  "mcpServers": {

    }

Please review this Ruby code for best practices and potential issues:

def process_data(items)
  items.map { |item| item.upcase }
end

Can you analyze this code for performance bottlenecks?

def find_duplicates(array)
  duplicates = []
  array.each do |item|
    if array.count(item) > 1 && !duplicates.include?(item)
      duplicates << item
    end
  end
  duplicates
end

Please check this authentication code for security vulnerabilities:

def authenticate(username, password)
  user = User.find_by(username: username)
  if user && user.password == password
    session[:user_id] = user.id
    true
  else
    false
  end
end

I need ideas for improving user onboarding in my Ruby on Rails app. The current flow has a 60% drop-off rate.

I'm struggling with this algorithm problem. Can you help me think through it step by step?
