What you can do
The server exposes 16 tools across five categories:| Category | Tools |
|---|---|
| Files | create-file, list-files, get-file, update-file, delete-file, generate-file-name |
| Screens | list-screens, get-screen, get-screen-image |
| AI generation | ai-prompt, upload-attachment |
| Chat | get-chat-history |
| Design | get-design-guidelines, update-design-guidelines, delete-design-guidelines |
| Billing | get-plan-details |
Common use cases
Generate screens from a prompt — ask your AI assistant to create a new Flowstep file, runai-prompt, then call get-screen-image to see the result inline.
Visualise a React component — upload your .jsx or .tsx file via upload-attachment (use mimeType: text/javascript), then pass the returned attachment into ai-prompt with a message describing the component. Flowstep reads the source and generates a matching design screen.
Iterate on a design — generate a base screen, upload it as an attachment, and call ai-prompt again with instructions to modify it.
Maintain design guidelines — call get-design-guidelines to retrieve your current style rules (colours, typography, spacing, tone), then use update-design-guidelines to keep them in sync as your design evolves. Passing consistent guidelines into ai-prompt ensures every generated screen stays on-brand. Use delete-design-guidelines to reset them entirely.
Audit quota — call get-plan-details to see remaining daily and monthly usage before kicking off a batch of generations.
