Description
Cube is a platform designed to facilitate the filling of forms by agents on behalf of users. The core concept revolves around agent-native forms, which allow agents to fill out forms without the need to open a browser. This is particularly useful for users who rely on digital assistants or agents to manage their online interactions.

The platform supports various formats such as Markdown, JSON, and MCP, allowing for flexibility in how forms are filled and submitted. Users can create forms using a drag-and-drop builder, which offers 21 different field types. Once a form is created, it can be filled by an agent, and the submission is counted immediately as if the user had submitted it themselves.
Cube also supports file uploads, with options for sending files via multipart, Base64 in JSON, or through a link that the server fetches. This ensures that files are handled securely and efficiently, with a maximum file size of 10 MB per file and 50 MB per submission.
The platform offers a variety of tools through its MCP servers, allowing agents to list forms, read form details, submit forms, and manage form templates. These tools are designed to streamline the process of form management and submission, making it easier for agents to assist users.
Cube is ideal for businesses and individuals who want to automate form submissions and leverage digital agents to handle routine tasks. It provides a robust solution for managing forms and submissions, ensuring that users can focus on more critical tasks while their agents handle the details.
