Plan your week with Claude, straight from your real calendar

The setup, click by click

This is exactly how it works on claude.ai today. The Claude desktop app has the same screens.

1. Add a custom connector

In Claude, open Customize, then the Connectors tab. Click Add, then Add custom connector.

2. Name it One and paste the link

Type One as the name and paste https://mcp.withone.ai/mcp as the URL. Click Continue.

3. Add, then Connect

Click Add. Claude opens One's connector page and says you're not connected yet. Click Connect.

4. Pick what Claude can reach

One opens its own screen. Choose where Claude works (I picked Production) and click Continue. Then pick Specific and set Google Calendar to Read only.

5. Authorize

One shows exactly what Claude will get. Click Authorize. You land back in Claude with Connected to One.

6. Turn One on in a new chat

Start a new chat, click +, open Connectors and make sure One is switched on. Then paste the prompt above.

The prompts I use to plan my week

Start each one with "Using One" so Claude knows to check your calendar. Paste them as they are, or swap in your own day or time.

See the week and what can move

PromptCopy

Using One, what does my week look like, and what can I move?

What you get: your week laid out day by day, plus what you could move or skip.

Find time to focus

PromptCopy

Using One, find me two 90-minute focus blocks this week where nothing is booked.

What you get: two open 90-minute slots you can block off for deep work.

Start tomorrow right

PromptCopy

Using One, what's on my calendar tomorrow, and what should I do first?

What you get: tomorrow at a glance and the one thing to start with.

Walk into your next meeting ready

PromptCopy

Using One, prep me for my next meeting: who is on it, what it is about, and what I should know going in.

What you get: a short brief on your next meeting before you walk in.

Cut the meetings that could be an email

PromptCopy

Using One, which of my meetings this week could be an email or a shorter call?

What you get: the meetings worth shrinking, so you get hours back.

See every deadline coming

Using One, list every deadline in the next 14 days in order, and tell me which one is at risk.

What you get: your next two weeks of deadlines in order, with the risky one called out.

Find out where last week went

Plan Monday hour by hour

PromptCopy

Using One, plan my Monday hour by hour around what's already booked.

What you get: an hour-by-hour Monday that works around your fixed meetings.

One real week, start to finish

I ran the week prompt on my own calendar on Nov 12. Names stay out of this guide, so here is what happened in plain words.

1. Claude asked first. Before it touched my calendar it asked for permission to use One. I clicked Allow once, a few times, one for each action.
2. It laid out my week. Day by day, from my real calendar, not a guess.
3. It told me what I could move. It flagged an optional meeting I could skip to free up time.
4. It didn't move anything itself. It ended by noting my calendar is connected read only, so the changes were mine to make.

You stay in control

• Claude asks before each action. You see a prompt with Allow once, Always allow or Deny. It gets permission, never your password.
• You see every call in One. One's home page shows what Claude can reach and its level, and Recent activity lists each thing it did.
• One click cuts it off. Open Manage access on Claude's card and click Revoke access.
