Claude Extensions

Reads the Messages history on this Mac and sends messages through the Messages app.

Setup: macOS protects the Messages database behind Full Disk Access. Claude does not need it: a small helper app, iMessage Reader, holds that access alone and keeps a private copy of your messages for this extension. Ask Claude to run the iMessage helper-install tool (or run imsg helper-install --yes): it installs the helper and opens System Settings → Privacy & Security → Full Disk Access. Switch on "iMessage Reader" there (drag it in from the Finder window if it is not listed). No restart needed. Sending asks once for permission to control Messages.

Connects to your WhatsApp account as a linked device, like WhatsApp Desktop.

Setup: in Claude, ask "link my WhatsApp". A page with a QR code opens in your browser. On your phone: WhatsApp → Settings → Linked devices → Link a device, and scan it. Then ask Claude to pull your messages.

Your keys and messages stay on this Mac. You can unlink it any time from WhatsApp → Settings → Linked devices.

Connects to your Telegram account as a linked device, like Telegram Desktop.

Setup:

1. Go to https://my.telegram.org, log in with your phone number, open API development tools and create an app (any name). Copy its App api_id and App api_hash into this extension's settings.
2. In Claude, ask: "link my Telegram". A page with a QR code opens in your browser. On your phone: Telegram → Settings → Devices → Link Desktop Device, and scan it.

Your session stays on this Mac. You can disconnect it any time from Telegram → Settings → Devices.

Reads, searches and answers your email: lists and searches messages, reads them, saves attachments, and writes replies and drafts. Nothing is ever sent without your confirmation in Claude.

Setup with Gmail (about five minutes, free, once):

1. Install Claude in Chrome and sign in to Google in Chrome with the address to connect.
2. In Claude, ask: "set up my email". Claude calls google_setup and walks you through Google Cloud Console in Chrome, click by click: a project of your own, the Gmail API, and a sign-in client of type Desktop app. You type passwords and accept terms yourself.
3. Paste the Client ID and Client secret Google shows into this extension's settings (or just leave the downloaded file in Downloads).
4. Claude calls connect: a Google page opens, you choose your account and allow access. Your sign-in stays on this Mac.

The same Google project and client also work for the Google Drive extension. Connect more addresses by asking Claude to connect another account.

On a Mac without Google: accounts already set up in the Mail app (iCloud, Outlook, any IMAP, Gmail too) work with no Google project. Ask Claude to connect your Mail app account, and allow Claude to control Mail when macOS asks. Search is slower there.

Search your Notion workspace, read pages and databases (with filters and chosen columns), list comments including resolved ones, and create or edit pages, rows and comments.

Unlike Notion's official connector, this extension acts as the account you are signed in with: it sees every page and database that account can see, with no integration to add page by page. Every change it makes appears in Notion under your name.

Setup:

1. In Google Chrome (or Arc, Brave or Edge) on this Mac, sign in at https://www.notion.so.
2. In Claude, ask: "connect my Notion". The first time, macOS asks whether security may use the "Chrome Safe Storage" keychain item: type your Mac password and click Always Allow. This copies your Notion session from Chrome into the extension; nothing is sent anywhere but Notion.
3. Ask away, for example: "search my Notion for the onboarding checklist".

Several workspaces: Claude picks the first one and tells you the others. Ask "connect my Notion workspace <name>" to switch, or type the workspace name in this extension's settings.

When Notion signs you out (Claude will say the session expired), sign in at notion.so in Chrome again and ask Claude to connect once more.

Creating, editing or deleting anything in Notion always asks you first. Exported agent settings are saved in Downloads/Notion.

Searches your Google Drive (including shared drives), reads Google Docs, PDFs and spreadsheets, and can write to Google Sheets when you ask it to. Several Google accounts can be connected side by side.

It signs in through your own Google Cloud project, so your files are only shared between Google and this Mac. Claude sets it up with you, once, in about ten minutes:

1. Open Claude in Chrome (the Claude extension for Google Chrome), in the Chrome profile where you are signed in to your Google account.
2. Ask Claude: "set up Google Drive". Claude reads the current steps from this extension and goes through Google Cloud Console with you, click by click: a project, the Drive and Sheets APIs, the sign-in screen, and a "Desktop app" client whose file lands in your Downloads folder. If you already set up the Email extension, Claude reuses that same project.
3. Claude then opens Google's sign-in page: pick your account, click Advanced → Go to ... (unsafe) when Google says it has not verified the app (it is your own app), tick every box and click Continue. If macOS asks whether Claude may read your Downloads folder, click Allow.

The settings below are optional: the client is found in Downloads on its own. To disconnect, ask Claude to disconnect Google Drive, or remove the app at https://myaccount.google.com/connections .

Brings your conversation history from ChatGPT, Claude (claude.ai chats), Codex cloud and Cowork into Claude: list your conversations, read one in full, and search everything across products.

Setup:

1. In Google Chrome (or Arc, Brave, Edge), sign in to the products you want to read: chatgpt.com, claude.ai.
2. In Claude, ask: "connect one-conv to my ChatGPT". macOS asks whether "credential-helper" may use the "Chrome Safe Storage" keychain item: type your Mac password and click Always Allow. This happens once; later reads never ask again.
3. Ask: "pull my ChatGPT history". Claude copies your conversations onto this Mac (100 by default, more on request), then can list, read and search them.

Your conversations stay on this Mac. If Claude says a session expired, sign in to the product in Chrome again and ask it to pull once more.

Reads cafeyn.co with your subscriber account: find a title, list the articles of today's (or any past) issue, read an article as text, save it as a PDF, or archive a whole issue as page images, a PDF and text.

Setup:

1. In Google Chrome (or Arc, Brave, Edge), sign in to https://www.cafeyn.co with your Cafeyn account.
2. In Claude, ask: "what is in today's Le Figaro on Cafeyn?". The first time, macOS asks whether security may use the "Chrome Safe Storage" keychain item: type your Mac password and click Always Allow. This is how the extension reuses your browser session; nothing is sent anywhere else.

If Claude says the Cafeyn session expired, sign in to cafeyn.co in Chrome again and ask once more. PDFs and issue archives are saved in Downloads/cafeyn.

Reads Franc-Tireur with your subscriber account: articles from franc-tireur.fr (paywalled ones included), the contents of each issue, site search, and the printed edition from the digital kiosk (liseuse) as a readable PDF.

Setup:

1. In Google Chrome (or Arc, Brave, Edge), sign in to https://www.franc-tireur.fr with your subscriber account. For the printed edition, also open https://digital.franc-tireur.fr and sign in there.
2. In Claude, ask: "who am I on Franc-Tireur?". The first time, macOS asks whether security may use the "Chrome Safe Storage" keychain item: type your Mac password and click Always Allow. This is how the extension reuses your browser session; nothing is sent anywhere else.

The site session lasts about a day: if Claude says the paywall refused the session, reload franc-tireur.fr in Chrome and ask again. PDFs, pages and issue archives are saved in Downloads/franc-tireur.

miLibris runs the digital kiosk (liseuse) of many French titles, on addresses like digital.franc-tireur.fr. This extension reads the issues you subscribe to: tables of contents, articles as text, full-text search, and readable PDFs of whole issues.

Setup:

1. In Google Chrome (or Arc, Brave, Edge), open your title's digital kiosk and sign in with your subscriber account.
2. In Claude, ask: "list my miLibris kiosks". The first time, macOS asks whether security may use the "Chrome Safe Storage" keychain item: type your Mac password and click Always Allow. This is how the extension reuses your browser session; nothing is sent anywhere else.
3. If you subscribe to several kiosks, put the one you read most in this extension's settings (Kiosk address), or name it when you ask.

PDFs and issue archives are saved in Downloads/milibris. If a request says the session is missing, sign in to the kiosk in Chrome again and ask once more.

Reads your EcoleDirecte account (parent or student): grades, homework, timetable and the school messaging. It can also reply to or send a message to the school, always asking you first.

Setup:

1. In Claude, ask: "connect my EcoleDirecte". A page opens in your browser.
2. Sign in there with your usual EcoleDirecte username and password. They stay on this computer and are never typed into the chat.
3. The first time, EcoleDirecte asks a security question (for example your year of birth): click the right answer on the page.
4. Back in Claude, ask for example: "what homework is due tomorrow?".

You only do this once: the extension signs in again by itself when the session expires.

Reads your MyOralia (Oralia) co-owner space: your building and shares, the account statement and balance, general meetings, the agency's contacts, the agenda, and every PDF document, which it can save to your Mac.

Setup:

1. In Google Chrome, sign in at https://myoralia.fr with your co-owner account.
2. In Claude, ask: "connect my MyOralia account". macOS asks whether security may use the "Chrome Safe Storage" keychain item: type your Mac password and click Always Allow. This copies your Chrome session into the extension; nothing is sent anywhere else.

When MyOralia signs you out (Claude will say the session expired), sign in at myoralia.fr in Chrome again and ask Claude to connect once more. Documents are saved in the Download folder from this extension's settings (Downloads/MyOralia by default).

Reads the RentalReady owner portal (pms.rentalready.io) as you: this month's occupancy and net revenue, every reservation with its financial breakdown (rent, commission, cleaning, platform fees, tourist tax), monthly totals, a year-end projection, and your property's details.

Setup:

1. In Google Chrome (or Arc, Brave, Edge), sign in to https://pms.rentalready.io with your owner account, including the two-factor code.
2. In Claude, ask: "how is my RentalReady rental doing this month?". The first time, macOS asks whether security may use the browser's "Safe Storage" keychain item: type your Mac password and click Always Allow. This is how the extension reuses your browser session; nothing is sent anywhere else.

The portal signs you out after about two weeks. When Claude says the session expired, sign in to pms.rentalready.io in Chrome again and ask once more.

Search tracks, albums and artists, browse charts and an artist's top tracks and radio: no setup needed.

To use your own account (likes, playlists, Flow, listening history):

1. Log in at https://www.deezer.com in Google Chrome (or Arc, Brave or Edge) on this Mac.
2. Ask Claude, for example: "what are my latest Deezer likes?". The extension reads your Deezer session from the browser.
3. The first time, macOS may ask whether to allow access to "Chrome Safe Storage": click Always Allow.

If that does not work, paste your arl cookie into this extension's settings instead (deezer.com → View → Developer → Developer Tools → Application → Cookies → arl).

Liking a track or changing a playlist always asks you first.

Reads Merkl's public campaign data: the campaigns a wallet created, the campaigns on a token, their budgets, APR targets, windows, scoring progress and cancellations. Read-only: it never signs or sends anything.

Setup: none. Ask Claude, for example: "list the live Merkl campaigns created by 0x…" or "show Merkl campaign 0x…".

Optional, to check whether a campaign paid through a confidential airdrop was really funded ("was this campaign paid?"), fill these settings (Claude Desktop → Settings → Extensions → Merkl → Configure):

1. Ethereum RPC URL: an archive-capable RPC endpoint, such as an Alchemy or Infura URL with its key. Public RPCs refuse the history reads this needs.
2. Airdrop campaign types and Airdrop factories: ask your team for the values.
3. Merkl API key (optional): the campaign creator's key, to net out what Merkl hands back to the creator.

Reads the audit reports of your project on audits.openzeppelin.com, and can submit or remove your team's official response to an issue.

Setup:

1. Install Google Chrome if it is not on this Mac, and sign in at https://audits.openzeppelin.com in it.
2. Open your project there and copy the part of the address after audits.openzeppelin.com/ (for example your-org). Paste it into this extension's Organization setting.
3. Ask Claude, for example: "list our OpenZeppelin audits". The extension reads your session from Chrome. The first time, macOS may ask whether to allow access to "Chrome Safe Storage": click Always Allow.

When the session expires, sign in again in Chrome and retry. Submitting or removing a response always asks you first.
