Overview

AI-generated overview

Hosted MCP server for Sello webshop and marketplace accounts: read orders, products, messages and sales stats, and update order status and stock.

What you can do
  • Read account details, orders with rows, deliveries and history, and order statuses
  • Browse products with prices, stock and change history, plus suppliers and connected marketplace integrations
  • Review marketplace sync messages and count unread ones
  • View sales summary, daily and monthly turnover, stock worth and top sellers
  • Update an order's status, notes or new-flag, and set a product's stock quantity
  • Check usage, request a feature, upgrade or cancel the subscription
When to use it
Useful when you run a Sello shop and want an assistant to answer questions about orders, stock and turnover, or to make small changes such as moving an order to another status or correcting stock levels without opening Sello.
Requirements
Remote streamable HTTP endpoint; no local install. Connect with the server URL only, then sign in via OAuth with your Sello credentials and provide a Sello API key from the account settings, which the server stores per user. A free plan allows 50 tool calls per month; paid plans are available.
Before you install
Two tools write to your shop: updating an order can trigger Sello automations such as mail and stock changes, and setting a product quantity syncs the new stock to all active marketplaces. The server stores your Sello API key, and your shop data passes through a third-party host. Paid plans are billed through a checkout link, and cancelling gives no refund for the current period.

Installation

In SourceWeft

  1. Open Sello MCP by usefulapi in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.usefulapi%2Fsello/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

Sello MCP by usefulapi

Use your Sello account from Claude, Cursor, or any MCP client. Read orders, products, messages and sales statistics, and update orders and product stock. Hosted, no local install: connect with your own credentials.

Live endpoint: https://sello.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://sello.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http sello https://sello.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
json
{  "mcpServers": {    "sello": {      "url": "https://sello.usefulapi.io/mcp"    }  }}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Sello credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/sello/

On first connect you provide a Sello API key (Sello → Account settings → API keys). The server validates it and stores it per user. No keys go in config files.
