# What is an MCP server for PrestaShop?

An MCP server for PrestaShop is a program that gives Claude, or another MCP-compatible client, tools to read and change a PrestaShop shop: search products, read orders, prepare a price change.

## What is MCP?

MCP (Model Context Protocol) is an open standard for connecting an AI to software. The server describes its tools, and the AI client (Claude Desktop, Claude Code, Cursor, Codex…) calls them when a question needs them.

## What should a good PrestaShop MCP server do?

- **Read without slowing down the site**: answer from a copy of the data rather than querying the live shop for every question.
- **Write nothing without approval**: the AI prepares, a person checks and applies.
- **Never expose passwords** of the shop or the server to the AI.
- **Keep a record and allow undo** for every change.

## What does the One Shop Manager MCP server contain?

The `one-shop-manager` server exposes 44 tools (version 0.4.56, full list in [docs/tools.md](https://github.com/oneshopmanager/prestashop-mcp/blob/main/docs/tools.md)). It runs inside the One Shop Manager software, which copies the shop to the computer.

| Family | Example tools | What they do |
|---|---|---|
| Shop | `shop_info`, `list_languages` | Open shop, languages |
| Catalog | `search_products`, `get_product`, `list_combinations` | Products, texts per language, categories, attributes and combinations |
| Customers and orders | `search_customers`, `list_orders`, `get_order` | Customer details, orders with gross margin |
| Analysis | `sales_report`, `stock_report`, `restock`, `seo_report` | Sales, stock valuation, restock, SEO audit, tables |
| Accounting | `accounting_summary`, `accounting_order` | Summary with VAT by country and rate, entries for one order |
| Journal | `list_journal`, `list_proposals` | Past operations, status of proposals |
| Catalog proposals | `propose_price_change`, `propose_texts`, `propose_product_create` | Prices, fields, texts and SEO, categories, product creation (disabled) |
| Combination proposals | `propose_combinations_create`, `propose_combination_stock` | Attributes, values, combinations, stock |
| Order proposals | `propose_order_state`, `propose_order_tracking` | Statuses, tracking numbers, new order |
| Undo | `propose_undo` | Undo an operation from the journal |

The `propose_*` tools write nothing to the shop: they compute the change and file it as a proposal in the AI log. You open the before/after preview, then click Apply. Read-only mode hides every proposal tool from the AI.

## What security guarantees?

- **Access disabled by default**, turned on in the software settings; "Test access" checks the connection.
- **Local server**: it only listens on the computer (`127.0.0.1`), and every request needs an access key. "New token" revokes the current key.
- **Credentials out of reach**: the shop keys and passwords stay in the system keychain.
- **Limited data**: only the data needed for the question goes to the AI provider; with your own Claude, it goes directly to Anthropic.
- **Undo**: everything can be undone from the journal, except an order created by the AI.

Details in [docs/security.md](https://github.com/oneshopmanager/prestashop-mcp/blob/main/docs/security.md).

## How do you install it, client by client?

First turn on access: in One Shop Manager, AI › AI settings, card AI access (MCP), check "Enable AI access", then click "Test access". The software must stay open on the shop.

### Claude Desktop

Quit Claude Desktop completely, click "Connect Claude Desktop", then reopen Claude. Alternatively, install the `prestashop-mcp.mcpb` extension published on [GitHub](https://github.com/oneshopmanager/prestashop-mcp/releases), which asks for the access key and the port.

### Claude Code

Copy the command shown by the software and run it in a terminal, once per computer:

```bash
claude mcp add --scope user --transport http one-shop-manager http://127.0.0.1:47715/mcp --header "Authorization: Bearer <ACCESS_KEY>"
```

In Claude Code, `/mcp` shows `one-shop-manager` as connected. It also works in the VS Code extension.

### ChatGPT desktop app and Codex

Choose ChatGPT (Codex) and click "Connect ChatGPT and Codex". In the ChatGPT app, then install the One Shop Manager plugin once from Plugins; restart Codex. ChatGPT in the browser cannot reach a local server.

### Cursor and other MCP clients

Add the block given by the software to `~/.cursor/mcp.json`:

```json
{
  "mcpServers": {
    "one-shop-manager": {
      "url": "http://127.0.0.1:47715/mcp",
      "headers": { "Authorization": "Bearer <ACCESS_KEY>" }
    }
  }
}
```

Other clients connect the same way (HTTP), or over stdio with the software executable. The software shows the real key and port.

## Where can you find it?

- Official MCP registry: `io.github.oneshopmanager/prestashop-mcp`.
- GitHub repository: [oneshopmanager/prestashop-mcp](https://github.com/oneshopmanager/prestashop-mcp), with documentation for each client and the Claude Desktop extension.

## What can you ask it?

- "Which products in stock have not sold in the last 90 days?"
- "Lower the price of these products by 15%, rounded to .90, without going under a 25% margin."
- "Write the missing meta descriptions for the Shoes category, in French and English."
- "Add the S, M, L and XL combinations to this sweatshirt."
- "Which paid orders have not shipped yet?"
- "VAT collected by country in the third quarter?"

More examples in [examples/prompts.md](https://github.com/oneshopmanager/prestashop-mcp/blob/main/examples/prompts.md).

## Frequently asked questions

### Do I need to install a module on the shop?
Yes. A small PrestaShop module bridges One Shop Manager and the shop webservice. The MCP server itself runs on your computer.

### Does the server work without the software?
No. The MCP server is part of One Shop Manager: the software must stay open on the shop for the AI to reach it.

### Which PrestaShop versions?
PrestaShop 1.6, 1.7, 8 and 9, on macOS 11+ and Windows 10+.

### Is the MCP server paid?
It is included in One Shop Manager at no extra cost: you use your own Claude or ChatGPT subscription. The software price is on the [Pricing](/en/pricing.md) page.
