listonic-mcp
An MCP (Model Context Protocol) server that gives AI agents — Claude, Cursor, or any MCP client — hands on your real Listonic grocery list. Read it, add to it, check things off, across every device Listonic syncs to.
The obvious win: meal planning that ends in a shopping list. Ask your agent to plan the week's dinners, and the missing ingredients land straight on the list on your phone — quantities and all. Or paste a recipe and say "add what I don't have": the server tells the agent which items are checked (already at home) and which aren't.
You: plan me 3 cheap high-protein dinners and put the ingredients on my list
Agent: [reads your list — sees you already have rice, eggs, frozen spinach]
[adds: 1 kg chicken thighs, 400 g lentils, greek yogurt ×2, ...]
Unofficial. Not affiliated with Listonic. Built on their web app's API (reverse-engineered — fully documented in API.md). It may break if Listonic changes their API.
Install
Requires Python 3.10+ and a Listonic account (free):
Add to your agent
Point command at listonic-mcp and pass your Listonic login:
{
"mcpServers": {
"listonic": {
"command": "listonic-mcp",
"env": {
"LISTONIC_EMAIL": "you@example.com",
"LISTONIC_PASSWORD": "your-listonic-password"
}
}
}
}
The same values can be passed as --email / --password args instead — whichever your client makes easier.
Claude Code
claude mcp add listonic -e LISTONIC_EMAIL=you@example.com -e LISTONIC_PASSWORD=your-password -- listonic-mcp
Cursor
Cursor Settings → MCP → New MCP Server, paste the JSON config above.
Google Antigravity
Add the JSON config above to .gemini/antigravity/mcp_config.json.
Then just ask:
What's on my grocery list? Check off the milk, I just bought it.
Launch params
| Param | Env var | Default | What it does |
|---|
--email | LISTONIC_EMAIL | — | Listonic account email (required). |
--password | LISTONIC_PASSWORD | — | Listonic account password (required). |
--list-id | LISTONIC_LIST_ID | first list | Pin a default list; see get_lists for the ids. |
| Tool | What it does |
|---|
get_lists | All your shopping lists with their ids. |
get_items | Items on a list — checked (already have) vs unchecked (to buy). |
add_items | Add one or many items in a single call (name, quantity, unit). |
edit_items | Check/uncheck, rename, or re-quantity items — batched. |
delete_items | Remove items entirely. |
Every tool takes an optional list_id, so multiple lists ("weekend BBQ", "pharmacy") work naturally.
Good to know
- Your password goes to Listonic only. The server logs in against
api.listonic.com directly and talks to nothing else — no telemetry, nothing stored beyond an in-memory session token (auto-refreshed when it expires).
- The client id/secret in the source are Listonic's own web-app credentials, embedded in their public JS bundle and shared by every web user — they are not personal secrets.
- The full reverse-engineered API is documented in API.md — lists, items, categories, account endpoints — if you want to extend the server.
Make it yours
A single readable file with no framework magic. Fork it and edit anything — add price tracking, category sorting, a recipe parser. Run from source:
git clone https://github.com/ArturLys/listonic-mcp.git
cd listonic-mcp
pip install -e .
listonic-mcp --email you@example.com --password your-password
