Ask your receipts
anything.

Step 1. Open GroceryTrack in Anthropic's connector directory at claude.ai/directory/grocerytrack and click Add. If you are not signed in to Claude the button reads Sign in to add; sign in to your Claude account first. You can also find it inside Claude under Customize → Connectors by searching for GroceryTrack.

Step 2. Claude opens the GroceryTrack authorization page. Sign in, or create a free account there with Google, Apple or email. Review the two permissions (your receipts, spending, pantry and notes; your price history) and click Allow. A confirmation page shows a few prompts to try, then sends you back to Claude.

Step 3. In any chat, click +, open Connectors, and make sure GroceryTrack is on. Then ask. Connectors belong to your Claude account, not to one device, so the same connection works in the web, desktop and mobile apps. The first time a tool draws a card, Claude asks once whether to show it.

Or by URL. In Claude open Customize → Connectors, click + Add, then Add custom connector. Name it GroceryTrack, paste the server URL, click Continue (Claude detects the OAuth settings on its own), choose Sign in now, and click Add.

https://grocerytrack.food/api/mcp

Adding by URL is the fallback for a Claude account that cannot see the directory. The directory listing is the same server, so either way you end up with the same connection.

Option A. Add it from the terminal (add --scope project to share it with a team through .mcp.json):

claude mcp add grocerytrack \
  --transport http \
  "https://grocerytrack.food/api/mcp"

Option B. Or add it to your .mcp.json file:

{
  "mcpServers": {
    "grocerytrack": {
      "type": "http",
      "url": "https://grocerytrack.food/api/mcp"
    }
  }
}

Step 1. Open ChatGPT Settings (click your profile icon in the bottom-left).

Step 2. Go to Connectors (called Apps in newer versions), open Advanced settings, and turn on Developer mode. Custom MCP servers need it, and it is available on paid ChatGPT plans.

Back in Connectors, click Create, name it GroceryTrack, and paste the server URL. Leave authentication on OAuth.

Step 3. Paste the server URL and confirm:

https://grocerytrack.food/api/mcp

Step 4. You'll be redirected to sign in, or create a free account, to authorize access. Once connected, ChatGPT can use all thirteen GroceryTrack tools. ChatGPT's rules keep upgrade links out of answers, so Pro-only depth is described in words there.

Step 1. Add the server to Cursor's MCP config. For every project, create or edit ~/.cursor/mcp.json; for one project, .cursor/mcp.json in its root. Remote servers take a url and nothing else:

{
  "mcpServers": {
    "grocerytrack": {
      "url": "https://grocerytrack.food/api/mcp"
    }
  }
}

Step 2. Open Customize in the sidebar (where Cursor lists MCP servers), make sure GroceryTrack is enabled, and sign in when Cursor asks. Cursor uses OAuth with PKCE and registers itself, so there is no client id to enter and no API key to paste.

Step 3. In Agent mode, ask a question. Cursor shows each GroceryTrack tool it calls; all of them are read-only, so there is nothing to approve beyond the first sign-in.

Google lets Gemini Spark connect to a custom MCP server by URL. It needs a personal Google Account on a paid Google AI plan (Pro or Ultra, depending on where you are), Keep Activity turned on, and English. Work and school accounts are not eligible. Custom apps are added on the web, and then work in Spark on mobile too.

Step 1. On gemini.google.com, open Settings & help → Connected apps. If you do not see it, look under Personal Intelligence first.

Step 2. Under Custom apps for Spark, click Add a custom app, paste the server URL, and click Next. Leave Advanced features collapsed: that is for servers that need manual client credentials, and GroceryTrack registers Gemini automatically.

Step 3. Sign in, or create a free account, in the GroceryTrack window that opens, review the two permissions, and click Allow. Then ask Spark about your groceries.
