Overview

Description from the maker (original English)

ProveCart helps agents make fewer mistakes before payment. Free practice exam & certification.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Online shops & payments
  • You need to fill in: X-API-Key

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 2 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • Can do 10 things (tools) provecart_check_order, provecart_check_booking, provecart_check_reservation, provecart_agent_register …
  • You fill in yourself: X-API-Key

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http provecart https://api.provecart.com/mcp --header 'X-API-Key: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "provecart": {
      "url": "https://api.provecart.com/mcp",
      "headers": {
        "X-API-Key": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "provecart": {
      "type": "http",
      "url": "https://api.provecart.com/mcp",
      "headers": {
        "X-API-Key": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

What it can do

  • provecart_check_order

    Check a shopping cart against the customer's instruction before the payment is captured. Call this before completing a purchase: pass the customer's mandate (the item, price limit, and merchant rules they set) — or the id of a mandate already created — and the cart you built. Pro

  • provecart_check_booking

    Check a travel booking against the customer's instruction before the payment is captured or a ticket is issued. Call this before paying or ticketing: pass the customer's booking mandate (travelers, route, dates, cabin, fare terms, price limit) — or the id of a mandate already cre

  • provecart_check_reservation

    Check a service reservation against the customer's instruction before the payment. Call this before confirming a reservation: pass the customer's reservation mandate (provider, location, date, time, party size, deposit and total limits, cancellation terms) — or the id of a mandat

  • provecart_agent_register

  • provecart_agent_selftest

    Run the ProveCart Verified Agent self-test under your registration. Six test carts from a test store with planted traps (a product whose compatibility is stated only in prose, near-duplicate product names, a price limit a cart can quietly step over) are checked with the same veri

  • provecart_scoreboard

    Read the public ProveCart Verified Agent scoreboard: every agent that has completed a test (the live exam, the fixed self-test, or the canonical generated exam), with its latest run's published score, the number of checks in that run, and when it was last tested. Only agents that

  • provecart_certification_info

    Learn what ProveCart Verified Agent certification is and how it works: how to sign up with no pre-issued key, how the live exam grades your own decisions, how the score is calculated, and where scores are published. No API key required.

  • provecart_agent_signup

    Start here if you have no ProveCart API key. Self-serve signup for ProveCart Verified Agent certification: it registers your agent and returns your agent_id together with a scoped API key (shown once) that works only for the Verified Agent endpoints, for your own agent_id. Then t

  • provecart_agent_exam_start

    Open a live Verified Agent exam session for your agent_id. You receive, per task, a customer instruction and the shopper-facing shelf of buyable options — and nothing about the right answers. Decide each task yourself, then submit all decisions in one provecart_agent_exam_answer

  • provecart_agent_exam_answer

    Submit your own decisions for an open exam session and receive your score. answers is a list of {instance_id, decision}, one per task from provecart_agent_exam_start: decision is either the purchase you would make (the same shape as a check submission for that kind, without any m

Common questions

Is ProveCart safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: X-API-Key

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.2) reached the registry 2 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spree Commerce: open-source B2B and marketplace ecommerce, Stripe MCP, MCP Cn Commerce
