Drive-time check from a Google Drive file to Google Sheets
Which rows are within 15, 30 or 45 minutes' drive of a place. Ask your AI in plain English: it reads a Google Drive file, InstaMaps does the location work, and the results land in Google Sheets.

The prompt
Using the rows in this CSV or Excel file in my Google Drive: <link to the file>, tell me which addresses are within 15, 30 and 45 minutes' drive of <your address>, 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
The drive-time band each row falls in
How many rows are in each band
Anything that can't be placed or answered comes back with the reason. Nothing is dropped.

Drive-time check in Claude
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.
Business, Enterprise and Edu workspaces (in beta). An admin turns on developer mode first: Workspace Settings, then Permissions & Roles, then Connected Data.
Go to chatgpt.com/plugins, click +, then "Add custom MCP server".
Name it InstaMaps. Under Connection, enter https://get-instamaps.com/mcp as the server URL and choose OAuth.
Click "I understand and want to continue", then "Create as a plugin", and install it. Sign in with Google when asked.
The Gemini app with a personal Google account (US, 18 and over, English). Work accounts use Gemini Enterprise, where an admin adds InstaMaps: write to hello@get-instamaps.com for the sign-in details it needs.
On gemini.google.com, open Settings, then Connected Apps.
Under Custom apps, click "Add a custom app" and enter https://get-instamaps.com/mcp. Click Next and sign in with Google.
Share the file with InstaMaps, or set it to "anyone with the link can view". InstaMaps reads it straight from Drive.
Writing to Google Sheets
InstaMaps 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.
Good to know
Weekday drive times in Great Britain and the US.
The connector is free: 5,000 tool calls a day per person, and a whole sheet read by link counts as one call.
