For AI assistants

Make sign-up sheets from your AI assistant

Ask ChatGPT, Claude or another AI assistant to “make a potluck sign-up sheet” and it creates a real sheet on SignUpSheet.page: a link to share with everyone and a private organizer link for you. Free, no ads, and nobody needs an account.

Connector URL

Remote MCP server (Streamable HTTP). Authentication: none. No account or API key needed.

What you can ask

“Make a sign-up sheet for our class Thanksgiving potluck on Nov 20: 3 main dishes, 2 salads, 3 desserts, drinks, plates and cups.”
“Set up volunteer shifts for the school book fair on Dec 3 in Chicago, 8am–2pm in 2-hour shifts, 3 people each.”
“Help my book club find a night next week: Tuesday, Wednesday or Thursday at 7pm.”
“Make a farewell card for Sarah from the team and let people chip in $10 for a gift. My PayPal.Me is jdoe.”
“How is my potluck sheet going? (paste the sheet’s link)”

Your assistant asks for anything that is missing, then gives you the share link, the private organizer link and a printable QR flyer. Sheets work in 15 languages.

Add it to your assistant

Claude

Open Settings → Connectors, choose Add custom connector, paste the URL and save. Then ask Claude for a sheet in any chat.

ChatGPT

When SignUpSheet.page is listed in ChatGPT, add it from there. Until then, on plans with developer mode you can add a custom connector with the URL and No authentication.

Le Chat (Mistral)

Open Connectors, choose Add Connector → Custom MCP Connector, paste the URL and choose no authentication.

Perplexity

Where custom connectors are available on your plan, add a remote connector with the URL.

Grok

Open grok.com/connectors, choose New Connector → Custom and paste the URL.

Other apps

n8n, Make, Copilot Studio and other MCP clients: add the URL as a remote MCP server (Streamable HTTP, no authentication).

What the connector can do

create_signup_sheet — Makes a sign-up sheet: slots such as dishes, shifts or time slots, with optional dates and times and how many people each slot needs.
create_date_poll — Makes a date poll: people answer yes, maybe or no for each date or time.
create_group_card — Makes a group card for one person, with an optional chip-in for a gift.
get_sheet_summary — Reads how a sheet, poll or card is going from its public link. Read-only; it never returns email addresses.

No connector? Use a pre-filled link

Assistants that can only write a link (such as Copilot, Meta AI, the Gemini app or a text-message assistant) can send a link that opens our create form already filled in. Nothing is created until the person checks it and taps Create.

Never put email addresses or the organizer’s name in a link; the form asks for them. Up to 30 items. Keep links under 2,000 characters. Add via=ai so we can count links from assistants.

Examples

Privacy

Your assistant sends us only what is needed to make the sheet: the title, slots or dates, the organizer name, and an email address only if you give one. We never see your chat.
The private organizer link appears in your chat. Anyone with it can edit or delete the sheet, so do not share that conversation. Give your email and we also send you both links.
Sheets made from an assistant work like any other sheet, under the same privacy policy, and you can delete them at any time.
