User Feedback Management

AI applications can utilize the Fillout.io MCP Server to create and manage feedback forms, allowing users to provide detailed responses about their experience with a product or service. This data is then processed through API calls for further analysis.

const form = await client.createForm({
  name: "Customer Feedback",
  description: "Please share your experience",
  questions: [
    {
      type: "ShortAnswer",
      name: "What did you like most?",
      required: true
    },
    {
      type: "MultipleChoice",
      name: "Would you recommend us?",
      required: true,
      choices: ["Yes", "No", "Maybe"]
    }
  ]
});

Market Research Analysis

By implementing the Fillout.io MCP Server, organizations can streamline their market research processes through automated form distribution and analysis. This enables real-time insights into consumer preferences and trends.

const response = await client.submitFormResponse(formId, {
  responses: [
    {
      questionId: "q1",
      value: "Great customer service!"
    },
    {
      questionId: "q2",
      value: "Yes"
    }
  ]
});
