For UK addresses: the food hygiene rating, CQC rating, or the nearest A&E and the NHS trust running it. Ask your AI in plain English: it reads Google Sheets, InstaMaps does the location work, and the results land in Google Sheets.

The prompt
Using the rows in this Google Sheet: <link to your sheet>, add the food hygiene rating of the business at each address, and write the results into the same sheet as new columns beside the rows.
Replace the parts in <angle brackets>.
What comes back
The official record at each address, with its rating and date
Or the nearest registered place, such as an A&E
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.
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 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
UK registers (CQC, NHS, Food Standards Agency). Not available for US addresses.
The connector is free: 5,000 tool calls a day per person, and a whole sheet read by link counts as one call.
