What's in here

This repository is a Codex marketplace (qrstuff-codex-plugins) that distributes:

Plugin	Description
qrstuff-mcp-server	Official QRStuff plugin for OpenAI Codex. Connects the QRStuff MCP server to generate and manage QR codes and retrieve scan analytics.

When you install the plugin, Codex CLI registers the remote MCP server at https://mcp.qrstuff.ai/mcp for you.

Requirements

• OpenAI Codex CLI installed and signed in.

Installation

You can add the marketplace and install the plugin either from within an interactive Codex CLI session (using /marketplace slash commands) or from your terminal (using codex subcommands).

From within Codex CLI

1. Add this marketplace:

/marketplace add qrstuff/codex-plugins

2. Install the plugin:

/plugin install qrstuff-mcp-server@qrstuff-codex-plugins

From the terminal

codex marketplace add qrstuff/codex-plugins
codex plugin install qrstuff-mcp-server@qrstuff-codex-plugins

The qrstuff/codex-plugins shorthand resolves to this GitHub repository (https://github.com/qrstuff/codex-plugins). You can also pass the full URL:

codex marketplace add https://github.com/qrstuff/codex-plugins.git

Usage

Once the plugin is installed, the QRStuff MCP server is available to Codex automatically. Start (or restart) a Codex CLI session and the qrstuff MCP server will be connected.

You can then ask Codex to use QRStuff in natural language, for example:

"Generate a QR code for https://qrstuff.com using QRStuff."

To confirm the server is connected, list the active MCP servers:

codex mcp list

You should see qrstuff in the list of connected servers.

Updating

When a new version of the plugin or marketplace is published, refresh your local copy:

codex marketplace update qrstuff-codex-plugins

Uninstalling

Remove the plugin:

codex plugin uninstall qrstuff-mcp-server@qrstuff-codex-plugins

Remove the marketplace entirely:

codex marketplace remove qrstuff-codex-plugins

Troubleshooting

• Marketplace not found: make sure you ran codex marketplace add qrstuff/codex-plugins and that you have network access to GitHub.
• qrstuff server not listed in codex mcp list: restart your Codex CLI session after installing.
• Plugin not updating: versions are pinned via .codex-plugin/plugin.json. Run codex marketplace update qrstuff-codex-plugins to fetch the latest catalog.
