French Grocery costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation

Where are you running it?

Every route below installs the same thing and ends at the same approval screen. This one runs on your machine: your client starts French Grocery as a process under your own user, with your files and your network, so the tool surface below is what it can do to your computer rather than to a server somewhere else. Its scan result is on the Security tab — read the surface before you approve it.

Claude Codedeclared by this listing

This is a public server: you run it yourself and this marketplace is not in the path. You need Node.js — the current LTS (24) is the safe choice; npx comes with it. Claude Code registers it in one command; --scope user makes it available in every project. The '--' is in quotes so that PowerShell passes it on.

claude mcp add --scope user french-grocery-mcp '--' npx -y fr-grocery-mcp

Reconnect, or start a new session, and the tools appear in the model’s tool list.

Free on mcprush, and it runs from its publisher’s own package: this marketplace is not in the path, so there is no key of ours to hold and no card to add.

What it asks of you

Nothing is required, but it can take FR_GROCERY_CONFIG (Path to the optional JSON configuration file. Without it, only Super U is enabled.), FR_GROCERY_CHROME_PORT (Chrome DevTools Protocol port; overrides the configuration file.), FR_GROCERY_STATE_DIR (Directory for retailer state such as the selected Leclerc store.) if you want to set them.

What it writes

One config entry your client uses to start the process locally. A local server runs with your file system and your network, which is why it is priced without metering.

What you approve

11 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Tool surface

What the model actually sees. Descriptions are diffed on every release — see version history.

Only tools that write or reach the network

Read from its source code. A server that builds its tool list when it starts can list more tools than this.

Lists the plugged-in retailers and their capabilities (product page, store selection, minimum order, booked slot). With check: true, also checks that each session responds and shows the active store.

Parameter	Type	Required	Notes
check	boolean	no	query each site (read-only)

Searches the retailer's catalogue. For each product: id, label (brand and size included), price, price per kg/l/piece, availability, typed promotions (immediate, multibuy, loyalty) and best net offer.

Parameter	Type	Required	Notes
limit	integer	no	maximum number of products
query	string	yes	short search term (in French), e.g. "spaghetti", "boeuf haché 5%"
store	string	yes	retailer (see list_stores)

Reads a product page: ingredient list (allergens in capitals, possible traces), allergen statement if the site provides it, and origin. Ingredients are null for a raw product (fruit, fresh meat).

Parameter	Type	Required	Notes
product_id	string	yes	retailer product identifier (id field of search_products)
store	string	yes	retailer (see list_stores)

Reads the retailer's actual cart: lines (id, label, quantity, line total, unit price) and total.

Parameter	Type	Required	Notes
store	string	yes	retailer (see list_stores)

Reads, for one retailer or all of them (store omitted), the selected store, the booked slot, the next pickup and delivery slots (structured dates) and the minimum order. Books nothing.

Parameter	Type	Required	Notes
store	string	no	retailer; omitted = all of them, one after the other

Adds units of a product on top of those already present, then reads the cart back to confirm.

Parameter	Type	Required	Notes
product_id	string	yes	retailer product identifier (id field of search_products)
quantity	integer	no	sale units to add
store	string	yes	retailer (see list_stores)

Sets a product's quantity in the cart (replaces the current one; 0 removes the product), then reads the cart back.

Parameter	Type	Required	Notes
product_id	string	yes	retailer product identifier (id field of search_products)
quantity	integer	yes	desired final quantity
store	string	yes	retailer (see list_stores)

Removes a product from the cart entirely, then reads the cart back.

Parameter	Type	Required	Notes
product_id	string	yes	retailer product identifier (id field of search_products)
store	string	yes	retailer (see list_stores)

The retailer's stores around a postcode or town, nearest first (if the retailer supports it, see list_stores).

Parameter	Type	Required	Notes
query	string	yes	postcode or town, e.g. "75011"
store	string	yes	retailer (see list_stores)

Selects the retailer's active store among the find_stores results and remembers it. The site session must be on this store: on "session expired", open it on the site.

Parameter	Type	Required	Notes
store	string	yes	retailer (see list_stores)
store_id	string	yes	id field of find_stores

Reads each retailer's cart: total, lines, minimum order and missing amount, next slots. Sorted from cheapest to most expensive.

Parameter	Type	Required	Notes
mode	string	no	targeted fulfilment mode

ATrust score 96 / 100

Release 0.1.1 · scanned 28 Oct 2026

Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.

What the scan could actually read

A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.

Live transportnot available

Tools were statically extracted from the published source (11 recovered), not enumerated from a running server. Tool-poisoning, Unicode-smuggling, capability and toxic-flow analysis ran on this inferred surface, but a mis-parsed registration could be missed or mis-attributed, so tool-derived findings are capped below “confirmed”. To grade the real runtime surface, scan the running server: --command "npx -y <package>".

Capability — what it could do if the model were manipulated

Tags derived from each tool’s schema and the implementation, not from what the tool calls itself. moderate is the level these add up to.

Toxic-flow graph

The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.

flow-1

Untrusted input can drive an external action even though no sensitive source is exposed.

This is the first scan of this surface here, so there is nothing yet to compare it against.

Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.
