How it works

About a minute to set up, once

  1. Add the connector

    Paste the connector URL into your assistant's connector settings. The steps for each app are below.

  2. Sign in with your email

    The first time, your assistant opens a Festoonify sign-in. Tap the link we email you, then Allow.

  3. Share a photo and ask

    Attach a photo or describe the space. You get three looks, a shopping list, and previews of your own photo decorated.

Set it up in your assistant

Every app uses the same connector URL

Claude

  1. Open Settings Connectors.
  2. Choose Add custom connector and paste the connector URL.
  3. Sign in with your email when Claude asks, then Allow.
https://mcp.festoonify.com

ChatGPT

  1. Turn on developer mode in ChatGPT's settings.
  2. Add a connector (app) and paste the connector URL.
  3. Sign in with your email when ChatGPT asks, then Allow.
https://mcp.festoonify.com

Grok

  1. Go to grok.com/connectors.
  2. Choose New connector Custom and paste the connector URL.
  3. Pick OAuth if it asks about authentication, then sign in with your email.
https://mcp.festoonify.com

On Grok Business or Enterprise, an admin adds the connector for the team first.

Meta Muse

  1. Open Settings Connectors Add custom connector.
  2. Paste the connector URL.
  3. If Muse asks about transport and authentication, pick HTTP and OAuth, then sign in with your email.

Cursor, VS Code, Gemini CLI and more

  1. Any app that supports remote MCP servers can connect to the same URL.
  2. Add this to its MCP config. It opens the same email sign-in the first time.
{
  "mcpServers": {
    "festoon": { "url": "https://mcp.festoonify.com" }
  }
}

Custom GPT (Actions)

  1. In the GPT builder, add an action.
  2. Import the schema from this URL.

Actions have no sign-in, so a custom GPT shares daily limits and can't use a Season Pass. Use the connector to get your own account.

Things to ask

Tap one to copy it, then paste it into your chat with a photo

Free photos and the Season Pass

Your assistant uses the same account as the website, so the same pricing applies

3

free photos

Every account gets 3 free photos. Each one becomes a space with three looks and a shopping list.

$10

Season Pass

When the free photos run out, your assistant links to the pass: one payment, 12 months, no subscription. Buy it with the same email, then ask again.

1

account everywhere

A pass works in every assistant you connect, and spaces made in a chat show up in My spaces.

For developers and agents

A remote MCP server (Streamable HTTP) that follows the MCP authorization spec

Tools

get_christmas_decor_ideas
Three decorating looks for a photo or description of a space, sized to an optional budget_usd, with estimated prices, product links, a space_id and a private preview_url.
preview_look
The person's own photo decorated with one look (space_id and look 1 to 3). Takes 20 to 40 seconds.
find_christmas_decor_products

When an account is out of free photos or previews, a tool returns pass_required: true and a buy_url to show the person, instead of an error.
