How does this MCP find the cheapest store?

It compares the total cost of your items across different stores, including unit prices, discounts, and travel expenses.

Does it account for gas money?

Yes, the MCP calculates travel expenses as part of the total cost to ensure the cheapest option is actually the most economical.

Can I use this with Claude?

Yes, you can connect this MCP to any MCP-compatible client, including Claude, Cursor, and Windsurf.

What happens if a store is out of an item?

You can use the substitution capability to see if a different brand or product is a valid and cost-effective replacement.

How do I get started?

You subscribe through Vinkius, which hosts the MCP for you, and then connect it to your preferred AI client with one click.

How does the capability calculate the cheapest store?

The compare_baskets capability calculates the total cost for each store by summing item prices (adjusted for package size) and adding the specific travel cost for that location.

What happens if an item is out of stock?

The engine uses evaluate_substitution to check if a valid replacement is available. A store is only considered a valid option if it can fulfill 100% of your list through direct matches or valid substitutions.

Does it account for travel costs?

Yes, travel costs are a fixed overhead included in the total cost calculation for every store to ensure you find the true cheapest option.

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

How Vinkius works: one connection, every tool, in any AI

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Curated set · 4 capabilities

One connector, every AI

Grocery Store Comparator works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put Grocery Store Comparator to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.
