Live warnings check from Google Calendar to Google Sheets
Which of your places are inside a flood or storm warning in force right now. Ask your AI in plain English: it reads Google Calendar, InstaMaps does the location work, and the results land in Google Sheets.

Take my Google Calendar events from last month that have a location, check which of these places are inside or within 5 km of a flood or storm warning in force right now, and put the results in a new tab of this Google Sheet: <link to a sheet>.
Replace the parts in <angle brackets>.What comes back
- Inside, near or clear, for every place
- The warnings that touch it: kind, level and end time
- Anything that can't be placed or answered comes back with the reason. Nothing is dropped.

Every plan, including Free. On Free, InstaMaps uses your one custom connector; Google Drive, Gmail and Google Calendar are directory connectors and don't count against it.
- In Claude, open Settings, then Connectors, and choose "Add custom connector".
- Name it InstaMaps and paste https://get-instamaps.com/mcp. Click Add.
- Click Connect and continue with Google. You land back in Claude, ready to ask.
- Add the Google Drive, Gmail or Google Calendar connector from the same Connectors page when the chain uses them.
- Paste the prompt above.
Before you start
Reading Google CalendarConnect your AI tool's Google Calendar connector. The events pass through the chat, which is fine for a month of visits (a few hundred events).
Writing to Google SheetsInstaMaps writes to the sheet itself: share it with the address the answer gives you, as Editor. It adds new dated columns or a new tab, and never overwrites a cell.
Run it on a schedule
Every morning at 6am: take my Google Calendar events from last month that have a location, check which of these places are inside or within 5 km of a flood or storm warning in force right now, and put the results in a new tab of this Google Sheet: <link to a sheet>.
- Claude. Scheduled tasks run a prompt hourly, daily, on weekdays or weekly, with the connectors you've added. They need a paid plan (Pro, Max, Team or Enterprise), and on Pro and Max they run in the cloud, so your computer can be off.
- ChatGPT. ChatGPT has scheduled tasks, but OpenAI doesn't yet say whether they can use a custom connector. Run the prompt by hand until it does.
- Microsoft Copilot and Teams. Copilot Studio agents can run on a schedule with a Recurrence trigger. The run uses the agent author's sign-ins.
- Gemini. Google doesn't yet say whether scheduled actions can use a custom app. Run the prompt by hand until it does.
Good to know
- England flood warnings and US weather warnings, plus earthquakes and other global alerts. Warning areas are the issuers' own.
- The connector is free: 5,000 tool calls a day per person, and a whole sheet read by link counts as one call.
