n8n Claude + SubmitRax to Generate & Host Forms on GitHub Pages

Generate SubmitRax forms with Claude and publish them automatically to GitHub Pages

This n8n workflow uses an Anthropic Claude Sonnet agent (via the SubmitRax MCP server) to generate form HTML from your prompt, then updates or creates the corresponding HTML file in your GitHub Pages site—returning the comment, form key, and a hosted URL.

What this workflow does

• Receives your prompt using the n8n Chat Trigger.
• Generates a SubmitRax form by sending the prompt to a Claude Sonnet-backed agent (via the SubmitRax MCP server), which returns structured output containing:
  • a comment
  • a form key
  • the generated HTML
• Checks GitHub Pages content for an existing file at forms/<formKey>.html in your configured GitHub repository.
• Publishes the form by updating the existing HTML file or creating a new one in the GitHub repository.
• Returns results with the agent’s comment, the form key, and the GitHub Pages hosted URL to the published form.

Use cases

• SaaS operators who need consistent, generated forms for landing pages or onboarding flows without manual HTML work.
• Automation engineers building a prompt-to-publish pipeline for form generation and hosting on GitHub Pages.
• Teams iterating quickly on form design: regenerate HTML and automatically replace the version at forms/<formKey>.html.

Technical details

• SubmitRax form generation using a SubmitRax MCP Tool with an API token configured via n8n HTTP Bearer Auth.
