123FormBuilder — form and submission management

integrations

123formbuilder is a Claude Code skill that connects Claude Code to 123FormBuilder via the Membrane CLI, enabling management of forms, submissions, and user accounts. Membrane handles authentication and credential refresh automatically, so no manual auth plumbing is needed. Three interaction modes are available: discovering available actions by natural language intent (`membrane action list`), running them with input parameters (`membrane action run`), and sending proxy requests directly to the 123FormBuilder API with automatic authorization headers. The skill is well suited for automating online form data collection, processing survey responses, and integrating form workflows without writing authentication logic from scratch. Requires the Membrane CLI installed and a Membrane account (free tier supported).
