Connect CalcForms
There are three ways in. They all open the same forms and the same dashboard.
ChatGPT
Open the official CalcForms app, click Add, and sign in with your email. A free ChatGPT account works. From then on you build, edit and check on your forms by chatting.
Claude, and other MCP clients
Add https://forms.badabingapp.cc/mcp as a connector. The setup guide walks through it step by step for Claude. Any client that speaks MCP over streamable HTTP and supports OAuth 2.0 can connect the same way.
Web dashboard
Sign in at /login with a one-time code sent to your email, or with your password if you set one, to open your dashboard. The dashboard is where you see submissions, export them, and manage webhooks and branding.
How sign-in works
Sign-in uses OAuth 2.0. When you connect from ChatGPT or Claude you are sent to a CalcForms consent page, you sign in there, and the assistant receives a token scoped to your account. CalcForms never sees your ChatGPT or Claude password, and they never see yours.
The token an assistant holds carries the same permissions as your dashboard session and no more: it can only reach your own forms and submissions. Disconnecting the connector from ChatGPT or Claude stops further access.
