The planner's address for your AI

Claude

On claude.ai, or in the Claude desktop app:

1. Open Customize, then Connectors.
2. Choose Add, then Add custom connector.
3. Name it “Wedding planner”, paste the address above, and continue. Leave the sign-in as Claude finds it, and add it.
4. Choose Connect. You come here to sign in, and the planner asks “Let Claude use your wedding plan?”: choose Allow.

Then, in a chat, check it's switched on under +, then Connectors. Once it's added, the Claude phone app can use it too. On the free plan, Claude allows one custom connector. Claude's own help.

Claude Code

In a terminal: claude mcp add --transport http wedding-planner https://thebigdayplan.com/mcp

Then, in Claude Code, type /mcp, pick the planner, and sign in when your browser opens. Claude Code's help.

ChatGPT

ChatGPT can use the planner only through its developer mode, on the web. Today, OpenAI lets it make changes only in Business, Enterprise and Edu workspaces; on Pro it can only read your plan, and other plans can't add it. If that rules it out, copy and paste works with any plan (below).

1. On chatgpt.com, open Settings, then Apps, then Advanced settings, and switch on Developer mode (in a workspace, an admin may need to allow it).
2. Back in Apps, choose Create. Name it “Wedding planner”, paste the address above, and choose OAuth to sign in.
3. Choose Scan Tools. You come here to sign in, and the planner asks “Let ChatGPT use your wedding plan?”: choose Allow. Then choose Create.
4. In a chat, pick it from +, then More.

Gemini

Gemini can use the planner as a custom app, added on the web. Today, Google offers custom apps only in English, to people 18 or over in the US, signed in with a personal Google account (not a work or school one) with Keep Activity on. Google lists them under Gemini Spark, which it offers on its Google AI Pro and Ultra plans, so you may need one of those. If that rules it out, copy and paste works with any plan (below).

1. On gemini.google.com, open Settings, then Connected Apps (if it isn't there, open Personal Intelligence first).
2. Under Custom apps, choose Add a custom app, paste the address above, and choose Next. Leave Advanced features as they are.
3. You come here to sign in, and the planner asks “Let Gemini use your wedding plan?”: choose Allow.
4. In a chat, type @ and pick it. Once it's added, the Gemini phone app can use it too, and Gemini asks you to confirm each change.

Gemini CLI

In a terminal: gemini mcp add --transport http --scope user wedding-planner https://thebigdayplan.com/mcp

Then start gemini. When your browser opens, sign in, and the planner asks “Let this program use your wedding plan?”: choose Allow. If it doesn't open, type /mcp auth wedding-planner. Gemini CLI's help.

Any other AI

Another app that takes a remote MCP connector, with sign-in, can use the same address in the same way.

For any AI at all, there's copy and paste: “Copy for your AI” copies your whole plan, with instructions, to paste into any chat; when you've agreed changes, “Paste your AI's changes” shows you what each would do, and you apply all, some or none. Those two buttons are coming to the planner's screen soon.

What your AI can and can't do

• It reads your whole plan, guests and your private notes included, and only when you use it.
• It quotes the planner's own answer and figures. The planner does the sums, never the AI.
• It's told to ask you before each change, and each change it makes reaches your plan as one from another phone would. Claude also asks you to allow each change: keep that on.
• If your plan has changed since it last looked, its change isn't made: it gets the newer plan and asks you again.
• It can't yet invite people, send messages, take card payments or publish your site. Only the couple can connect an AI; helpers can't.
• To stop it, remove the planner from your AI's connectors.
• What you say to your AI is between you and its maker, under their terms.
