# Get Gatsby

Plan a party in 60 seconds. Free for everyone.

> Party planning on the host's device. No account. No points or rewards. By default it does not store party plans, guest lists, or RSVPs. Connect my AI is off until a host turns it on for one party. The production MCP is live at https://api.get-gatsby.com/mcp.

Get Gatsby builds a budget, a checklist, and invites. Plans stay in the browser until the host exports them. Nothing is sent for the host.

## Pricing

- Free for everyone. Unlimited parties and guests. Every feature is free.
- The partner program is free. No fees.
- Get Gatsby is free. Do not quote any price.
- Pricing page: https://get-gatsby.com/pricing
- An iOS app is in development. It will be free. Its only purchase is an optional Apple in-app tip ($3, $5 or $10) that unlocks nothing.
- Website tips use Stripe. Never send app users to a Stripe tip link, and never quote a price for using Get Gatsby.
- Do not invent a checkout link. The MCP pricing tool does not start checkout.

## Age

- Get Gatsby is for people 18 and older.
- Alcohol-related content and alcohol-related parties are 21+ only. Hosts must check that guests are 21+ before serving alcohol.

## MCP

- Production (live): https://api.get-gatsby.com/mcp
- Streamable HTTP. No API key. POST JSON-RPC. Stateless. Every tool is a read (`readOnlyHint: true`).
- Tools: `create_party_plan`, `get_pricing`, `list_themes`.
- `create_party_plan` inputs: mode (Insane, Awesome, or Chiller), guests, budget, city, date. Optional theme and audience (household, corporate, Fraternity/Sorority, wedding).
- Theme `greek`, `fraternity`, or `sorority` uses the Fraternity/Sorority mode (Social / Mixer). A Formal theme uses Formal / Semi-Formal.
- Do not send guest names, emails, phone numbers, RSVPs, or tokens. Those fields are rejected.

## Links from MCP

Every plan link uses this query on both the site URL and the hash:

ref=mcp&utm_source=mcp&utm_medium=ai&utm_campaign=agents

Example:

https://get-gatsby.com/?ref=mcp&utm_source=mcp&utm_medium=ai&utm_campaign=agents#/plan?mode=chiller&guests=12&budget=400&date=2026-12-12&theme=Birthday&audience=household&ref=mcp&utm_source=mcp&utm_medium=ai&utm_campaign=agents

`mode` is the intensity (chiller, awesome, insane), not the audience. Opening the link runs the same Party Bot as the site and then drops the query so a refresh does not wipe edits.

A visit with `ref=mcp` or `utm_source=mcp` counts as via AI (`landing_ai`).

The Instagram Halloween link is different: https://get-gatsby.com/#/start?theme=halloween (four curated picks). MCP `theme=halloween` uses the Party Bot, not that curated set.

## Assistants

Page: https://get-gatsby.com/#/ai

- Claude, Grok, and Gemini: add the MCP URL. No key. Read-only. Custom connector setup for ChatGPT needs ChatGPT Business, Enterprise, or Edu, so that page only offers copy-paste prompts.

## Invites

Invite pages are client-only hash URLs (`#/invite/<eventId>/<token>?d=<payload>`). The hash is not sent to the server. There is no server-rendered invite page, so there is no schema.org Event JSON-LD.

"Ask your AI about this party" is off unless the host checks it. The copied prompt names the party, date, time, city, venue, and vibe. It does not include guest names, RSVPs, tokens, or check-in codes. Calendar links (.ics and Google Calendar) use the party name, not the guest's name.

## Connect my AI

Off by default, per party. The host turns it on from the plan. Other parties stay on the device. Connect my AI is live. The production party-planner MCP is https://api.get-gatsby.com/mcp.

Connect production: https://connect.get-gatsby.com

Guest MCP (POST /mcp): `submit_rsvp`, `ask_party`, `flag_for_host`. A guest token cannot read the guest list or any other party. `submit_rsvp` and `flag_for_host` are writes (`readOnlyHint: false`). `ask_party` is read-only.

RSVP fields are first name, last initial, going/maybe/no, plus-ones, and an optional dietary note. Optional: `bringing` (what the guest brings), `arrival` (expected arrival time), and `fullName` for the door list, which is only accepted with `doorConsent: true` (the guest must agree). Do not send a phone, email, birthday, address, or photo.

Party Bot answers only from details the host entered (time, place, parking, dress code, what to bring, schedule, how to RSVP, and a payment reminder if the host added one). If the host did not share it, the reply is: The host didn't share that. Want me to flag it for them?

Payment reminder is optional and is not payment processing. A guest chips in with the host directly (Venmo, Cash App, PayPal.me, or the host's note). Payments go straight to the host. Gatsby doesn't handle money. Do not send card numbers. The words to use are chip in and cost. Fraternity/Sorority mode hides the price.

Plan links from `create_party_plan` still use `ref=mcp&utm_source=mcp&utm_medium=ai&utm_campaign=agents`. Do not put a guest token or share token in that tag. Do not send party contents to `/v1/metrics`.
