GoodBarber MCP

Connect ChatGPT and Codex to your GoodBarber app

GoodBarber speaks MCP, the open standard for AI assistants. Plug in ChatGPT or OpenAI Codex and run your app in plain language — products, content, members, push.

GoodBarber has its own MCP server. ChatGPT reaches it through the GoodBarber plugin in its directory, and Codex connects to it natively. Set it up once with your GoodBarber account, then drive your app from the assistant you already use.

GoodBarber is in the ChatGPT plugin directory

The GoodBarber plugin is listed in the ChatGPT directory: search for GoodBarber, connect, and manage your app in plain language. No Developer mode needed. The steps are below, along with Codex and the full MCP server connection.

For developers

Codex

The OpenAI Codex app is a full MCP client. Add GoodBarber once in its settings and it stays available across your projects.

A GoodBarber app

  • An active GoodBarber app
  • Admin access to the app you want to connect

The Codex app

  • The OpenAI Codex app installed on your computer
  • A signed-in OpenAI account

  1. Open MCP servers in Codex

    In the Codex app, go to Settings, then Integrations, then MCP servers.

  2. Add a custom MCP

    Click Connect to a custom MCP to open the connection form.

  3. Name the connector

    Enter GoodBarber in the Name field.

  4. Choose Streamable HTTP

    For Transport, select Streamable HTTP (not STDIO).

  5. Paste the server URL

    https://mcp.goodbarber.dev/mcp/sse

  6. Leave the Bearer token empty

    Do not fill in the Bearer token field. Leaving it blank is what triggers the secure sign-in step.

  7. Save

    Click Save. Codex opens your browser to authorize the connection.

  8. Authorize GoodBarber

    Sign in to GoodBarber and approve access. You are sent back to Codex, connected.

  9. You are connected

    GoodBarber's tools are now available in Codex. Ask it to manage your app in plain language.

Heads up: the Bearer token field must stay empty. If you paste a token there, Codex skips the GoodBarber sign-in and the connection will not authorize.

Using Codex CLI?

Two commands: the first registers the GoodBarber server, the second opens the authorization page where you paste your Public API key.

For everyone

ChatGPT (desktop & web)

Two methods: install the GoodBarber plugin from the ChatGPT directory, or add the full MCP server as a custom plugin in developer mode.

picto-services-mcms

A GoodBarber app

  • An active GoodBarber app
  • Admin access to the app you want to connect

A ChatGPT account

  • A ChatGPT account. For method B, access to developer mode depends on your account and workspace policies.
  • Developer mode enabled, only for the custom plugin method.

Route A: the GoodBarber plugin from the ChatGPT directory

The recommended route for everyone: no Developer mode, and the free plan works.

  1. Find GoodBarber in ChatGPT

    In ChatGPT, open the plugin directory and search for GoodBarber, or open its listing directly using the button above.

  2. Connect and sign in

    Click Connect. Sign in to GoodBarber with an API key from your back office and approve access. Each key is tied to one app: that is the app ChatGPT will manage.

  3. Ask in any chat

    Mention GoodBarber, or just ask: create an article, look up a member, send a push. Write actions ask for your confirmation before they run.

Method B: the full MCP server as a custom plugin

Add the GoodBarber MCP server to ChatGPT by following the steps below. This method requires access to developer mode.

  1. Enable developer mode

    In ChatGPT, open Settings, then Security and login. In the Developer mode section, turn on Developer mode.

  2. Add a new plugin

    In settings, open Plugins, then click Browse plugins. On the Plugins page, click the + button in the top right to open the New plugin form.

  3. Name the plugin

    In the Name field, enter GoodBarber. The icon and description are optional.

  4. Enter the server URL

    https://mcp.goodbarber.dev/mcp/sse

  5. Choose OAuth

    Set authentication to OAuth so ChatGPT signs you in to GoodBarber securely.

  6. Create the plugin and authorize GoodBarber

    Read the ChatGPT warning, then select I understand and want to continue and click Create. Follow the steps to sign in to GoodBarber and approve access to your app.

  7. Use GoodBarber in a conversation

    Start a new conversation in ChatGPT and add GoodBarber from the tools menu. You can then ask, for example: “List the articles in my app.”

Developer mode is a beta feature, so the screens may change over time, and write actions ask you to confirm before they run. Access to Developer mode may depend on your account and workspace policies.

What you can do with it

Plain-language requests; GoodBarber does the work in your app. A few things our team ran while testing:

Content

Create a published article titled Spring Sale announcing 20% off the whole catalog until June 30.

Created and published the article, with the 20% off announcement.

Push notifications

Send a push to all my customers to announce the spring sale.

Created the push and queued it for broadcast, after you approved the wording.

Prefer a Custom GPT?

You can also connect GoodBarber through a Custom GPT with Actions — a different route from MCP, handy when you would rather share a ready-made assistant with your team. We will link the GoodBarber GPT here once it is live in the GPT Store.

Good to know

A few honest limits before you start.

Codex uses Streamable HTTP

In Codex, pick the Streamable HTTP transport — the setup steps above use the right option.

Available actions depend on your plan

Which GoodBarber actions the assistant can run depends on your GoodBarber plan and your admin rights.

Developer mode is in beta (custom connector route)

Developer mode is a beta feature in ChatGPT; availability and behavior can change, so it is worth a quick check on OpenAI's side. The plugin route does not use it.

You stay in control

Write actions ask for your confirmation before they run, and you can revoke access at any time.

Your app stays yours

Connecting an assistant does not hand over the keys.

Secure sign-in

You connect through OAuth: you sign in to GoodBarber and approve access. No password or token is shared with the assistant.

Scoped to your rights

The assistant can only do what your own GoodBarber account already allows — nothing more.

Revoke anytime

Disconnect GoodBarber from Codex or ChatGPT whenever you want; access ends immediately.

Privacy by design

GoodBarber keeps its privacy commitments for every connection. See our privacy policy.
