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.

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 sheet with InstaMaps, or set it to "anyone with the link can view". InstaMaps reads it straight from Google, so a sheet of thousands of rows is one call, and nothing passes through the chat.
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
Great Britain and the US, from public crime and hazard data. Each rating says its source and date.
The connector is free: 5,000 tool calls a day per person, and a whole sheet read by link counts as one call.
