## Set it up
### Mileage log 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.
1. In Claude, open Settings, then Connectors, and choose "Add custom connector".
2. Name it InstaMaps and paste https://get-instamaps.com/mcp. Click Add.
3. Click Connect and continue with Google. You land back in Claude, ready to ask.
4. Paste the prompt above.

### Mileage log in ChatGPT
Business, Enterprise and Edu workspaces (in beta). An admin turns on developer mode first: Workspace Settings, then Permissions & Roles, then Connected Data.
1. Go to chatgpt.com/plugins, click +, then "Add custom MCP server".
2. Name it InstaMaps. Under Connection, enter https://get-instamaps.com/mcp as the server URL and choose OAuth.
3. Click "I understand and want to continue", then "Create as a plugin", and install it. Sign in with Google when asked.
4. Paste the prompt above.

### Mileage log in Microsoft Copilot and Teams
Through Copilot Studio, with a Copilot Studio licence. Your Microsoft 365 admin approves the agent before the rest of the organisation can use it.
1. In Copilot Studio, open your agent, then Tools, "Add a tool", "New tool", and choose Model Context Protocol.
2. Name it InstaMaps, enter https://get-instamaps.com/mcp as the server URL, choose OAuth 2.0 with dynamic discovery, then Create and "Add to agent".
3. Publish the agent, then under Channels choose "Teams and Microsoft Copilot" and "Add channel". Share it from Availability options.
4. Paste the prompt above.

### Mileage log in Gemini
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.
1. On gemini.google.com, open Settings, then Connected Apps.
2. Under Custom apps, click "Add a custom app" and enter https://get-instamaps.com/mcp. Click Next and sign in with Google.
3. In a chat, type @ and pick InstaMaps to use it.
4. Paste the prompt above.

## Before you start
Reading Google Sheets
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.
## Run it on a schedule
Every 1st of the month, for the month before: using the rows in this Google Sheet: , work out the road miles for each trip, starting and ending at , and total the miles, and write the results into the same sheet as new columns beside the rows.
* **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
* Road distances in Great Britain and the US, on normal weekday traffic. Decide which trips are business: a claim is only as good as that list.
* The connector is free: 5,000 tool calls a day per person, and a whole sheet read by link counts as one call.
* Rather do it without an AI? [Use the free tool on our site](/tools/distance-between-addresses).
