Does this work on the free Claude plan?

Yes. Custom connectors work on every Claude plan. Free accounts can add one custom connector, so Plek.je can be that one.

What can the assistant change on my site?

Almost everything you can do in your Ghost admin: posts, pages, tags, members, newsletters, tiers and offers, comments, your theme and design, staff and integrations — whatever you allow on the consent screen. It cannot delete your site, change your plan, read your password, transfer ownership or connect payments.

Does it ask before doing something big?

Yes. Deleting a member or staff user, bulk changes, imports, themes, redirects, webhooks, integrations and anything involving money wait for your own confirmation: your assistant gives you a link to Plek.je and waits while you decide there, then carries on. Nothing happens until you confirm, and a request stays open for a day.

Can it sign readers up to my newsletter?

Only with their consent. When you ask it to add someone to a newsletter, your site emails them a confirmation link and they are subscribed once they click it. It never re-subscribes someone who unsubscribed.

How do I take access away?

Open your Plek.je account page and click Disconnect next to the app. To remove access to just one site, use Assistant access in that plekje's Advanced settings, or suspend the "Plek.je assistant" staff user in your Ghost admin.

Which assistants work?

Claude (web, desktop, mobile and Claude Code), ChatGPT (Plus and up, in Developer mode on the web), Codex, Gemini Spark, Gemini CLI and any other app that can add a remote MCP server with sign-in. It is the same address for all of them.

Is my writing used to train AI?

Plek.je never uses your content to train anything. What the assistant you connect does with it is between you and its provider; check their data settings.

Features & pricing Use with AI

Included with every plekje

Run your Ghost blog from Claude or ChatGPT.

Every plekje has a built-in AI connector. Add one address to your assistant, sign in once, and ask it to write, publish and look after your site — no API keys, no code, nothing to install. It works on every Claude plan, including Free.

Your connector address

https://plek.je/mcp

What you can ask

Your assistant can read and change posts, pages, tags, members, newsletters, images and site settings on every plekje in your account. A few things people ask:

“Draft a post about our spring workshop from these notes, add the tag “events” and save it as a draft.”
“Publish yesterday's draft and send it to the newsletter.”
“Which of my posts from last year had no feature image? Add suitable ones from these links.”
“How many members signed up this month, and who are they?”
“Rename the “Misc” tag to “Notes” and move the navigation link for About to the end.”
“Change the site description to something shorter and friendlier.”

Connect your assistant

Takes about two minutes. You need a Plek.je account with a plekje, and an account with the assistant you use. Pick yours:

Claude on the web, desktop and mobile

Works on every Claude plan, including Free.

Open Connectors in Claude
In Claude on the web, desktop or mobile, open Customize, then Connectors.
Add a custom connector
Click "+" (or "Add custom connector"). Give it the name Plek.je.
Paste the Plek.je address
Enter https://plek.je/mcp as the MCP server URL. If Claude asks how it should identify itself, keep "Use Claude's published identity". Leave client ID and secret empty.
https://plek.je/mcp
Connect and sign in
Click Add, then Connect. A Plek.je window opens: sign in with the account that owns your plekje.
Choose what Claude may do
Plek.je shows exactly what Claude asks for. Untick changes if you only want it to read, then click Allow.
Use it in a chat
In a new chat, open "+" → Connectors and make sure Plek.je is switched on. Then just ask, for example: "List my plekjes" or "Draft a post about…".

Good to know

On the Free plan you can add one custom connector. Plek.je counts as that one.
On a Team or Enterprise plan, an owner adds the connector under Organization settings → Connectors first; everyone then connects it for themselves.
Connectors are per chat: if Claude says it has no Plek.je tools, switch the connector on under “+” → Connectors.
Claude asks before running anything that changes your site. You can set tools to “Always allow” in the connector's settings.

Claude Desktop extension

Prefer an extension in Claude Desktop instead of a custom connector (for example because your Free plan's connector slot is taken)? Download the Plek.je extension and open it: Claude Desktop installs it with one click. The first time it is used, your browser opens to sign in to Plek.je, exactly as above.

Download plekje.mcpbClaude Desktop on macOS or Windows · Settings → Extensions also accepts it by drag and drop

Claude Code

Add the connector once from your terminal, then run /mcp inside Claude Code to sign in.

claude mcp add --transport http plekje https://plek.je/mcp

ChatGPT

ChatGPT adds your own connectors as apps in Developer mode: on the web, on the Plus, Pro, Business, Enterprise and Edu plans.

Turn on Developer mode
In ChatGPT on the web, open Settings → Security and login and switch on Developer mode. On a Business, Enterprise or Edu workspace an admin has to allow it first.
Create an app for Plek.je
Open Plugins in the sidebar and click "+" (Create MCP app). Give it the name Plek.je.
Paste the Plek.je address
Enter https://plek.je/mcp as the MCP server URL and choose OAuth for authentication. Leave client ID and secret empty: ChatGPT registers itself. Accept the notice about custom apps and click Create.
https://plek.je/mcp
Sign in and choose what ChatGPT may do
A Plek.je window opens: sign in with the account that owns your plekje. Untick changes if you only want it to read, then click Allow.
Use it in a chat
In a new chat, type @ and pick Plek.je (or choose it under "+" → Developer mode). Then ask, for example: "List my plekjes". ChatGPT asks you to confirm before anything changes.

Good to know

ChatGPT's Free plan cannot add custom apps. Claude's Free plan can, so that is the free way in.
Developer mode is for the web version of ChatGPT. Apps you add there are marked “custom” and are not available in the mobile app.
ChatGPT shows a warning for every custom app: it is ChatGPT's standard notice, not something specific to Plek.je.
On a Business, Enterprise or Edu workspace, an admin allows custom apps under Workspace settings → Permissions & roles first.

Codex

Add the connector to the Codex CLI or IDE extension, then sign in; your browser opens to Plek.je.

codex mcp add plekje --url https://plek.je/mcp

codex mcp login plekje

Gemini (with Spark)

Gemini connects your own apps through Gemini Spark, its always-on agent. Spark comes with Google AI Pro in the US, and with Google AI Ultra in most countries — not yet in the EU, the UK or Switzerland.

Open Connected apps in Gemini
On a computer, open gemini.google.com with your personal Google account, then Settings → Connected apps → Custom apps for Spark.
Add a custom app
Click "Add a custom app" and give it the name Plek.je.
Paste the Plek.je address
Enter https://plek.je/mcp as the server URL. Leave client ID and secret empty: Gemini registers itself.
https://plek.je/mcp
Sign in and choose what Gemini may do
A Plek.je window opens: sign in with the account that owns your plekje. Untick changes if you only want it to read, then click Allow.
Ask Spark
Ask Gemini Spark, for example: "List my plekjes". Gemini asks you to confirm before anything changes. Once connected, it also works in the Gemini mobile app.

Good to know

Custom apps need a personal Google account aged 18 or over with Keep Activity on; work and school accounts cannot add them.
You add the app on the web; after that it is available wherever you use Spark.
In Europe? Gemini CLI below works everywhere, and so do Claude and ChatGPT.
Using Gemini Enterprise at work? Its admin adds Plek.je with a client ID and secret: email support@plek.je to get them.

Gemini CLI

Add the connector once from your terminal, then run /mcp auth plekje inside Gemini CLI to sign in through your browser.

gemini mcp add --transport http --scope user plekje https://plek.je/mcp

Cursor, VS Code and other MCP apps

The same address works in any app that can add a remote MCP server with sign-in (OAuth). No client ID or secret is needed: apps register themselves. Add an MCP server of type HTTP (sometimes called “Streamable HTTP”) with the address below; the app opens Plek.je in your browser to sign in.

https://plek.je/mcp

What it can reach, and how to stop it

You decide

When you connect, Plek.je shows exactly what the app asks for. Reading and changing are separate: untick changes and it can only look. It never sees your password.

A visible staff user

Inside each site the assistant works as a staff user called “Plek.je assistant”. You can see it under Settings → Staff in your Ghost admin, and suspend it there.

Disconnect any time

Your account page lists every connected app with a Disconnect button, which works at once. To remove access to one site only, use Assistant access in that plekje's Advanced settings. Plek.je never uses your writing to train AI (privacy policy).

It says it couldn't connect: Check the address has no typo and starts with https. If your assistant connects but a tool says your site is paused or not online, start it from your plekjes. Still stuck? Email support@plek.je — a person will answer.
