Sello MCP by usefulapi

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:

{
  "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.
