instacart_add_to_cart
Add a product to the Instacart cart. Searches for the product and adds the first matching result.
LABSCO SUMMARY
Shop Instacart from a chat: search, fill a cart, compare stores, then order.
The price comparison is the useful extra: it checks one product's price across all available stores near you in one step. Until your assistant confirms, the order tool returns a preview instead of placing the order, and its own instructions say to confirm only after you explicitly agree.
What it is
An Instacart shopping client covering the whole path from session to placed order: login, search, cart building, store comparison, preview and checkout.
What you get
- instacart_place_order states in its own description that confirm should be set true only with explicit user agreement — the guard is in the tool text rather than assumed.
- instacart_preview_order shows the cart summary and delivery window before anything is committed, which is the step that makes the confirmation meaningful.
- instacart_compare_prices checks a product across all available stores near you, which is the comparison nobody does by hand.
- Cart operations are complete: add a product by search, view contents with quantities and totals, and clear it.
- Session handling as its own group — check status, initiate a login flow that returns a URL for the user to complete, and log out clearing cookies.
- instacart_set_address sets the delivery location, and instacart_stores lists what serves it.
Requirements
An Instacart account, authenticated through a login flow the user completes in a browser. Placing an order spends real money on a saved payment method.
Setup effort
One command — npx -y @striderlabs/mcp-instacart
USE CASES
01
Getting connected
Check the session status, run the login flow which returns a URL for you to complete in a browser, and set the delivery address.
02
Finding out where something is cheapest
Compare the product's price across every store serving your address, rather than repeating the search per store.
03
Building a basket
Add products, review the cart with quantities and totals, and clear it if you are starting over.
04
Checking before you commit
Preview the order for the summary and delivery window, then place it only with explicit agreement — the tool asks for that in its own text.
12 tools
Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.

instacart_compare_prices
Compare prices for a product across all available stores near you. Returns results sorted cheapest-first with store name and price-per-unit on each result.
