Claude Connector vs Claude Code vs Codex for Websites

One MCP server, several front doors. The Beste server works from Claude on the web, desktop or phone, from ChatGPT, from Claude Code or Codex in a terminal, and from Cursor, Gemini CLI or Grok. They all call the same tools and build the same site. They differ in where you sit, how long a session can run, where your rules live and how much you can automate.

This post is part of our MCP guide. It is about picking a client, not about picking a model.

The short answer

Quick edits, content work, anything from a phone: Claude with the connector.
You already live in ChatGPT, or want to watch a new site appear: the ChatGPT plugin.
Long builds, bulk changes, repeatable work: Claude Code or Codex in a terminal.
You already work in Cursor: Cursor, connected from the dashboard.

Most people end up using two of these. We use the connector for small changes and Claude Code for everything that takes more than ten minutes.

Side by side

Claude with the connector runs on the web, on the desktop and on your phone. You add the connector once. It is best for quick edits, content work and anything you do from a phone, and your rules live in the project instructions.

ChatGPT with the plugin runs inside ChatGPT. You install the plugin once. It is best for new sites with a live preview and for everyday edits, and your rules live in the project instructions.

Claude Code runs in a terminal and is set up with npx beste-agent@latest. It is best for long builds, bulk work and anything that uses local files, and your rules live in CLAUDE.md or AGENTS.md.

Codex runs in a terminal, in the IDE extension and in the ChatGPT desktop app, and is set up with the same npx beste-agent@latest. It is best for long builds if your subscription is with OpenAI, and your rules live in AGENTS.md.

Cursor, Gemini CLI and Grok run in their own apps and connect from the Beste dashboard. They are best for people who already work there, and your rules live in each tool's own rules files.

Claude with the connector

What it is. A connector added to Claude. Anthropic's support article on custom connectors describes how remote MCP connectors work in Claude and Claude Desktop, on Free (limited to one custom connector), Pro, Max, Team and Enterprise plans. On Team and Enterprise, an owner adds the connector to the organization first, and each person then connects with their own account.

How it connects. Add the connector once, sign in with your Beste account and approve the projects Claude may work on. Nothing to install and no key to copy. You can switch connectors on or off per conversation from the "+" menu, and remove access to a project at any time. The Connector for Claude page has the steps.

Where it shines. Anything you would otherwise do by opening the editor for five minutes. Fix a typo, change a price, add a team member, draft a post, check how a page reads in Spanish. From a phone, on a Sunday, while the client's message is still open in another app. Because it is Claude, it also has whatever else you have connected: your files, your calendar, your notes.

Where it is limited. Long sessions. A full site build or a 46-page translation is a lot of tool calls in a chat window, and you will want a terminal for that. It also runs only when you are in a conversation; it is not a script you can schedule.

One habit worth keeping. Claude asks before it uses a tool, and offers to allow it always. Anthropic's guidance is to choose "Allow always" only for servers and tools you trust to run unsupervised. For Beste, every change lands in the draft, so allowing writes is low risk. Publishing still needs your request.

ChatGPT with the plugin

What it is. The Plugin for ChatGPT, which runs on the same server as everything else in this post.

How it connects. Install the plugin from its page in ChatGPT and sign in with your Beste account once. As with Claude, you approve the projects ChatGPT may touch and can remove access per project.

Where it shines. Starting a site. Describe the business and you watch the sections land in a live preview next to the chat, then get a link to keep working on it. It is also good for everyday edits: new hours, a new price, a page for a new service, found everywhere it appears, including the shared footer.

Where it is limited. The same as the connector: it is a conversation, not a long-running job. New sites start with placeholder images, and ChatGPT generates images with your Beste AI credits only when you ask for them.

Claude Code

What it is. Anthropic's agent for the terminal. It connects to MCP servers through its own configuration, described in the Claude Code MCP documentation. The /mcp command inside a session shows which servers are connected.

How it connects. One command: npx beste-agent@latest. It signs you in through the browser and configures the server. Signing out revokes the access.

Where it shines. Long, structured work. Build a whole site from a brief. Translate every page. Rewrite every meta description to a rule. Add a redirect for every URL from an old site, read from a CSV in the same folder. Claude Code keeps working through a long task list without losing the thread, and it reads local files, so your brief, your product list and your rules document can sit next to the project.

It also fits repeatable work. A CLAUDE.md file in the project folder is read at the start of every session, which is how we keep the tone consistent across months. Anthropic's memory documentation recommends keeping that file under about 200 lines and writing instructions concrete enough to check. If a project already has an AGENTS.md and no CLAUDE.md, recent versions of Claude Code read the AGENTS.md instead, so one file can serve both Claude Code and Codex. What goes in that file is the subject of Writing Rules for Your Website Agent.

Where it is limited. It is a terminal. If you do not already work in one, the connector is the better place to start. And it is as careful as the rules you give it, so give it rules.

Codex

What it is. OpenAI's coding agent. It runs in the Codex CLI, the IDE extension and the ChatGPT desktop app, and OpenAI's MCP documentation explains that those three share one MCP configuration, stored in ~/.codex/config.toml. Set up the server once and you can switch between them without redoing it.

How it connects. The same command, npx beste-agent@latest, sets it up. Codex is included in the ChatGPT plans listed on OpenAI's Codex pricing page.

Where it shines. The same long, structured work as Claude Code, for people whose subscription is with OpenAI rather than Anthropic. The Beste tools do not care which model calls them, so the steps in our multilingual post are the same in either.

Codex also has an approval setting per MCP server, default_tools_approval_mode. Its writes mode asks before any tool that is not marked read-only, which pairs well with a server that labels every tool as read or write. Reads run freely; changes wait for you.

Rules. Codex reads AGENTS.md files before it starts: a global one in ~/.codex/AGENTS.md, then one per directory from the project root down to where you are working. OpenAI's AGENTS.md documentation notes a default combined limit of 32 KiB, another reason to keep the rules short.

Where it is limited. The same as Claude Code: it is a terminal or an IDE, and it needs rules.

Cursor, Gemini CLI and Grok

Cursor, Gemini CLI and Grok connect from the Beste dashboard, or from an empty page in the editor, where you copy a ready sentence to start. They fit people who already do their work in those tools and do not want another one. The tool set is the same as everywhere else.

How we split our own week

A rough picture of how this plays out on beste.co:

Claude Code for anything with a list. New pages, new languages, site-wide SEO changes, the redirects after a URL change, the blog posts in this guide.
The connector in Claude for everything that is one thing. A changed number on the pricing page, a sentence that read wrong on a phone, a new post idea captured before it is lost.
Bestie in the editor when we are already in the editor and the change is right there.

The decisions, the rules and the final read are the same in all three. Only the chair changes.

Using more than one client on the same site

Because every client calls the same server, you can start a change in one and finish it in another. Two things keep that from getting messy:

One rules document, copied to each place. Keep the master as an AGENTS.md in your project folder and paste the same text into your Claude or ChatGPT project instructions. When you change one, change the others the same day.
One draft. All clients write to the same draft. If two sessions are open at once, finish and review one before starting the next, so you always know whose change you are reading.

What to look for in any client

Whichever you pick, the server should behave the same way behind it. The assistant should read before it writes, changes should land in a draft, publishing should happen only when you ask, and mistakes should be undoable. Those are properties of the server, not the client, and they are described on the MCP server page. If a client lets the assistant skip the reading step, that is a prompt problem, and the fix is in your rules.
