What is a Model Context Protocol (MCP) server?

The Sellfy MCP (Model Context Protocol) Server securely bridges your Sellfy store and your favorite AI desktop tools or assistants (such as Claude).

Instead of logging into Sellfy and manually navigating through your dashboard to look up sales figures, review products, or check customer orders, the MCP server allows your AI assistant to read and manage your store data securely through natural language commands.

Examples:

  • "Create a digital product called Autumn Presets at 19.99."
  • "Attach this file to Autumn Presets and publish it."
  • "Create a landing page for my new product, Autumn Presets."
  • "How did last week compare with the week before?"
  • "Which five products earned the most this month?"
  • "Show the orders from [email protected]."
  • "Create a 20 percent discount code NEWSLETTER valid until Friday."
  • "Draft an email campaign announcing Autumn Presets and send me a test."
  • "List the reviews from the last 30 days with fewer than four stars."
  • "Start a new draft of my store, add a page for the course bundle, and give me a preview link."
  • "Publish the draft."
  • "Add these license keys to Autumn Presets."

What AI can I connect with Sellfy?

  • Claude Desktop App
  • Cursor IDE
  • Codex
  • Gemini CLI
  • VS Code
  • Zapier AI Agents
  • And more!

The Sellfy MCP server isn't tied to a single AI model or provider. Instead, it works with any AI assistant application or client that supports MCP.

You can use it with any AI model as long as it's through an MCP-compatible host app or interface.

How does it work?

The Model Context Protocol (MCP) acts like a secure adapter. It allows your AI client to communicate with Sellfy's backend securely:

  1. You ask a question in your AI client (e.g., "How many digital downloads did I sell this week?").
  2. The AI requests data from the Sellfy MCP Server using secure authentication.
  3. The Sellfy MCP Server responds with the accurate data, allowing the AI to give you a clear, precise answer.

Steps to connect your AI agent

Connecting is super simple! It will be three steps.

  1. Add the server URL
  2. Sign in to Sellfy and approve access (a browser window will open)
  3. Re-authorize when prompted by Sellfy

Your AI agent may even be able to do the setup for you. Copy and paste this code:

Set up the Sellfy MCP server for me by following https://api.sellfy.com/agent-setup.md

For more specific instructions based on which AI you're using, read below.

Claude (claude.ai or the desktop app)

  • Add: Settings → Connectors → Browse connectors, find Sellfy and click Connect. If it is not listed for your organization, choose Add custom connector and paste the URL above.
  • Sign in: click Connect on the Sellfy connector and approve in the browser.
  • Re-authorize: Settings → Connectors → Sellfy → Disconnect, then Connect again.

Claude Code

claude mcp add --transport http sellfy https://api.sellfy.com/mcp
  • Sign in: inside a session run /mcp  , pick sellfy   and choose Authenticate; the browser opens on Sellfy.
  • Re-authorize: /mcp   → sellfy   → Clear authentication, then Authenticate again. Or remove and re-add the server:
claude mcp remove sellfy
claude mcp add --transport http sellfy https://api.sellfy.com/mcp

Codex CLI

codex mcp add sellfy --url https://api.sellfy.com/mcp
codex mcp login sellfy
  • codex mcp login   opens the browser on Sellfy; approve the access and return to the terminal. codex mcp get sellfy   shows the connection.
  • Re-authorize:
codex mcp logout sellfy
codex mcp login sellfy

ChatGPT and Codex app

  • Add: open the plugin directory, find Sellfy and choose Connect. Without the directory entry, open chatgpt.com/plugins, click + → Add custom MCP server, paste the URL above with OAuth as the authentication, then Create as a plugin.
  • Sign in: ChatGPT opens Sellfy in the browser when you first use the connector.
  • Re-authorize: remove the connector and create it again.

Cursor — add to .cursor/mcp.json  :

{"mcpServers": {"sellfy": {"url": "https://api.sellfy.com/mcp"}}}
  • Sign in: Cursor Settings → MCP shows sellfy   with a Login button; click it and approve in the browser.
  • Re-authorize: the same MCP settings entry offers Logout, then Login again.

VS Code — add to .vscode/mcp.json  :

{"servers": {"sellfy": {"type": "http", "url": "https://api.sellfy.com/mcp"}}}
  • Sign in: VS Code prompts to sign in when the server starts; the browser opens on Sellfy.
  • Re-authorize: Command Palette → MCP: List Servers   → sellfy   → Sign out, then start the server again.

Any other OAuth-capable MCP client connects the same way: give it the URL, then sign in when it asks.

What can I manage through AI?

Once connected, your AI assistant can perform store management tasks on your behalf.

Examples include:

  • Storefront design
    • Create and edit store pages, such as About pages, FAQs and landing pages, including each page’s title, URL, SEO fields, visibility and place in the navigation.
    • Add and edit page blocks: hero sections, text panels, product grids, newsletter signups, contact forms, social links, embed code and spacing, plus your store’s navigation and footer.
    • Change your theme, including fonts, colors, and button and background styles. On plans that support custom code, Claude can also edit your custom head and footer code.
    • Work on a draft copy of your storefront that you can preview before publishing, and restore an earlier backup if you need to undo a change.
  • Products
    • Look up your products and their details.
    • Create new products as unpublished drafts, and edit names, descriptions, prices, compare-at prices, SEO fields and stock.
    • Publish or unpublish products.
    • Upload downloadable files and organize what buyers receive, including folders, files, text notes and links.
    • Add, reorder or remove product images, and add video or audio previews from YouTube, Vimeo, SoundCloud or Spotify.
    • Manage product variants and bundles.
  • License keys
    • Turn license keys on or off for a product, using either generated keys or a pool of keys you upload.
    • Upload keys, view issued keys, revoke or reactivate a key, and remove unsold keys.

    • Set flat shipping rates by region for a product, or create reusable shipping profiles and apply them to products.
