Connect CalcForms in 60 seconds.

Pick your assistant. Copy the URL. Paste it in settings. Build your first form.

⚡
Requires Claude Pro ($20/mo) or ChatGPT Plus ($20/mo) — free tiers from those providers don't support custom MCP connectors yet.
Step 1 — Copy your MCP URL
MCP Server URL
https://forms.badabingapp.cc
Step 2 — Add it to your assistant
1
Open the Add custom connector dialog in Claude →
This deep-link opens the dialog directly. If it asks you to sign in first, sign in and click the link again.
2
Fill the two fields exactly like this:
Add custom connector BETA
Cancel Add
Name: Calcforms · URL: https://forms.badabingapp.cc
3
Click Add, then click Connect. A browser tab opens — sign in with your email (we'll send a 6-digit code). When you're back in Claude the connector shows as Connected. You're done.
1
Open chatgpt.com and sign in to your Plus account.
2
Click your profile (top-right) → Settings.
3
Click Apps & Connectors → Advanced settings → toggle on Developer mode.
4
Back on the connectors page, click Create (top right).
5
Name it CalcForms, paste the URL above into MCP Server URL, and keep Authentication: OAuth.
6
Click Create, then Connect. Sign in with your email (we'll send a 6-digit code).
7
Back in ChatGPT, the connector shows Connected. To use it in a chat, open the Tools menu and toggle CalcForms on.

Step 3 — Build your first form

Open a new chat with CalcForms enabled and try any of these:

"Build a mortgage calculator" "Make a freelance quote form with tax" "Tip calculator that splits by N people" "ROI form with payback period"

Your forms appear in your dashboard. Each gets a shareable URL like forms.badabingapp.cc/you/your-form.

Troubleshooting
I don't see "Connectors" in Claude
Connectors require Claude Pro, Max, Team, or Enterprise. On a free account they won't appear. If you're on a paid plan and still don't see it, your admin may have disabled custom connectors — ask them to enable MCP connectors in workspace settings.
ChatGPT says my account can't add connectors
You need ChatGPT Plus, Business, or Enterprise, plus Developer mode turned on under Settings → Apps & Connectors → Advanced settings. Free ChatGPT accounts cannot add custom MCPs yet.
OAuth window opened but nothing happened
Disable any popup blockers for forms.badabingapp.cc, then click Connect again. Sign in with your email — we'll send a one-time 6-digit code (check spam if it doesn't arrive in 30 seconds).
The model says "I don't have access to that tool"
In ChatGPT, open the Tools menu in the composer and toggle CalcForms on for that chat. In Claude, mention CalcForms by name in the first message ("use CalcForms to build…") so it picks the connector.
Where are my submissions?
Your dashboard lives at /admin. Sign in with the same email you used in the OAuth step. Each form's submissions, invites, and CSV exports live there.
