GoodBarber Skills

30 AI-powered skills to manage your GoodBarber app with any MCP-compatible client — eCommerce, Community, and Membership.

These skills connect to the GoodBarber MCP server and give your AI assistant structured workflows to manage your products, orders, customers, promotions, subscriptions, analytics, and more — all from a conversational interface.


What are Skills?

Skills are instruction files (.md) that teach an AI assistant how to perform specific tasks using your GoodBarber app's API via MCP (Model Context Protocol). Instead of manually calling API tools one by one, a skill orchestrates the full workflow — from data retrieval to formatted report — in a single natural-language request.

For example, asking "Show me my best sellers this month" triggers the best-sellers skill, which automatically fetches your orders and catalog, computes rankings, and returns a formatted report.


Quick Start

1. Connect the GoodBarber MCP

You need to add the GoodBarber MCP server as a custom connector in your client. The MCP server uses Server-Sent Events (SSE).

MCP Server URLs:

Setup URL
Single app https://mcp.goodbarber.dev/mcp/sse
Multiple apps https://mcp.goodbarber.dev/<app_id>/mcp/sse

Replace <app_id> with your GoodBarber app ID if you manage multiple apps.

Authentication: the GoodBarber MCP server uses a browser-based OAuth flow.

When your MCP client connects to the SSE endpoint, it may open an authorization page on mcp.goodbarber.dev. On that page, you will be asked to paste your GoodBarber Public API key and validate the authorization. Generate your Public API key from your app's GoodBarber backoffice, on the Public API / MCP server page.

Important:

  • Do not open the /authorize URL manually in your browser.
  • Start from the MCP client by connecting to the SSE endpoint.
  • The client generates the full authorization request parameters automatically (redirect_uri, client_id, state, code_challenge, etc.).

If you open the authorization page manually without those parameters, the authentication will fail.

Claude Desktop (Cowork):

  1. Open Settings > Connectors
  2. Click Add custom connector
  3. Enter the MCP server URL above
  4. The connector opens the GoodBarber authorization page — paste your Public API key there and validate

Claude Code (CLI):

# Single app
claude mcp add goodbarber --transport sse https://mcp.goodbarber.dev/mcp/sse

# Multiple apps
claude mcp add goodbarber --transport sse https://mcp.goodbarber.dev/<app_id>/mcp/sse

Then start a Claude Code session — on the first GoodBarber tool call, the CLI will open the GoodBarber authorization page in your browser. Paste your Public API key there and validate to complete the OAuth flow.

Cursor / VS Code / Windsurf:

Add to your MCP configuration file (.cursor/mcp.json, .vscode/mcp.json, etc.):

{
  "mcpServers": {
    "goodbarber": {
      "url": "https://mcp.goodbarber.dev/mcp/sse"
    }
  }
}

The first connection from your client triggers the OAuth flow in your browser — paste your Public API key on the GoodBarber authorization page and validate.

Any other MCP-compatible client:

Point your client to the SSE endpoint above. The GoodBarber MCP server follows the standard MCP protocol and works with any compliant client.

2. Install the skills

Clone this repo and copy only the skills for your app type:

git clone https://github.com/goodbarber/goodbarber-skills.git

Note: the examples below use Claude's local skills directory (~/.claude/skills/). If you use another client, copy the skill folders to the directory expected by that client.

eCommerce app:

cp -r goodbarber-skills/skills/ecommerce/* ~/.claude/skills/

Community app:

cp -r goodbarber-skills/skills/community/* ~/.claude/skills/

Membership app:

cp -r goodbarber-skills/skills/membership/* ~/.claude/skills/

Tip: If your GoodBarber app combines multiple types (e.g. eCommerce + Membership), install skills from both directories.

Warning: some skill names are shared across app types (for example weekly-digest, traffic-report, or push-broadcast). If you install skills from multiple directories into the same destination, rename them or place them in separate namespaces to avoid collisions.

3. Verify

Ask your AI assistant: "What skills do you have?" — it should list the installed GoodBarber skills.

Design Principles

All skills follow these rules:

  • Pagination-aware — Large datasets are filtered server-side, not blindly paginated
  • Fuzzy matching — Mention a product or collection by name; the skill resolves it
  • Workflow chaining — Every skill suggests 2–3 related skills to run next
  • No destructive actions without confirmation — Mutations always require explicit user validation
  • Structured output — Every skill returns a formatted report, not a one-liner

Compatibility

These skills work with any MCP-compatible AI client, including:

  • Claude Desktop (Cowork)
  • Claude Code (CLI)
  • Cursor
  • VS Code (Copilot, Claude, Cline, etc.)
  • Windsurf
  • Codex CLI
  • Gemini CLI
  • Any client supporting the Model Context Protocol
