GoodBarber Public MCP Server

GoodBarber is a no-code app builder for mobile and web apps: eCommerce, content, community and membership apps. GoodBarber MCP is the hosted Model Context Protocol server that lets an AI assistant connect to a GoodBarber app and manage it in natural language: catalog, orders, promo codes, articles and events, push notifications, customers, subscriptions and analytics. Everything is scoped to the app you authorize.

What is GoodBarber MCP?

• A remote MCP server hosted by GoodBarber at https://mcp.goodbarber.dev/mcp/sse. Nothing to install, no runtime on your machine.
• 150 tools organized in three families: shop (58), content (61) and community & membership (30), plus a guidance tool.
• MCP 2026-07-28 over Streamable HTTP. Earlier handshake-era clients still connect. The /mcp/sse path name is historical and kept for backward compatibility.
• OAuth 2.1 with Dynamic Client Registration and PKCE. You sign in with the Public API key of your app; the token is bound to that single app.
• Listed in the official MCP Registry as dev.goodbarber/goodbarber-public-mcp. The full tool catalog is published as a server card at https://mcp.goodbarber.dev/.well-known/mcp/server-card.json.

A GoodBarber app combines at most two product families, and the API key carries the rights granted in the back office. A session therefore only sees the tools that match the app and the key: a shop app exposes the shop, orders, customers and analytics tools, a content app the CMS and push tools, and so on.

Who is it for?

• App owners and teams who run a shop, a media or a community app and want to handle routine tasks from their assistant instead of the back office.
• Agencies and resellers who manage several client apps: one server entry per app, each with its own key.
• Developers and agent builders who need a documented, annotated tool surface over the GoodBarber Public API.

How to use GoodBarber MCP?

1. Create a Public API key in your app's back office, on the Public API / MCP server page. The rights you grant to that key define what the assistant can do.
2. Add the server to your client.

3. Authorize. On the first call, the client opens the GoodBarber authorization page. Paste your Public API key and validate. Do not open the /authorize URL by hand: the client generates the OAuth parameters (redirect URI, PKCE challenge, state) itself.
4. Ask. "Show me this month's best sellers", "create a 20% promo code on the summer collection and announce it with a push", "publish this article in the News section with a cover image".

Key features

Shop (58 tools). Products, variants and options (shop_list_products, shop_create_product, shop_create_variant, shop_update_option), collections and tags, product paragraphs and media, PDF attachments and slides, promo codes by amount, product, collection or tag (shop_create_promocode_amount, shop_create_promocode_collections), orders and shipping (shop_list_orders, shop_update_order_shipping), loyalty, customers and prospects, push broadcasts and notifications, and analytics (downloads, launches, page views, session times).

Content (61 tools). Sections, articles, events, places on maps, photos, videos and sounds, each with full create, read, update and delete, plus paragraph blocks you can add, edit and reorder (cms_create_article, cms_create_article_paragraph, cms_reorder_article_paragraphs, cms_create_event, cms_create_map).

Community & membership (30 tools). Push broadcasts and targeted push by user group (classic_create_push_broadcast, classic_create_push_by_groups), user groups and users, prospects with notes, active, expired and internal subscriptions (classic_list_active_subscriptions, classic_create_internal_subscription), and audience analytics (devices, OS versions, mobile OS distribution, launches, page views, session times).

Guidance built in. meta_get_tool_plan returns, for any tool, the recommended discover, call and verify sequence and the failure policy, so agents chain calls safely.

Annotated tools. Every tool carries a title and read-only, destructive and idempotent hints. Clients that honor annotations ask for confirmation before a write.

Adaptive surface. Only the families of the app and the rights of the key are exposed, which keeps the tool list short and relevant for the model.

Hosted and standard. No local process, no Node.js, HTTPS only, OAuth 2.1, official registry listing, published server card.

Use cases

• Rank the shop's best sellers this month and reorder the low-stock ones.
• Create a promo code and schedule a push notification announcing it.
• Publish an article with a cover image in the right section of the app.
• Create the next events of the season with their descriptions and visuals.
• Audit the catalog: products without image, description or price, orphan products.
• List the subscriptions expiring in the next 30 days and draft the follow-ups.
• Send a targeted push to one user group or subscription tier.
• Get a weekly digest of traffic, sales and content activity.

Resellers can rebrand the skills. Repository: https://github.com/goodbarber/goodbarber-skills

Several apps

Each API key is tied to one app. Add one server per app with the per-app URL https://mcp.goodbarber.dev/<app_id>/mcp/sse and authorize each one with its own key.

Security

You sign in before anything happens, and every action is scoped to your own app: an assistant connected to your app cannot reach anyone else's. The key's rights limit the tools, and revoking the key from the back office disconnects the assistant at any time. Write tools are flagged destructive so clients can confirm before acting. Never paste your API key in a prompt: it belongs only on the GoodBarber authorization page.
