Chorus is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
In Claude, open Settings, then Connectors.
Choose Add custom connector, give it a name, and paste the link.
If it needs a sign-in, Claude sends you to it. Then turn the connector on in a chat from the tools menu and ask.
Custom connectors are available on paid Claude plans; on Team and Enterprise accounts an admin may need to add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in Claude

Screened, no issues found
Screening looks for known threats and hidden instructions at the time of the check, and runs again weekly and whenever the tool list changes. It cannot see the server's code, so only connect what you need and review what Muse asks to do. How screening works.
start_bookStarts a book of voice, video and written messages and returns its handle and the single link the organiser sends to everyone taking part. The book is for one person or a couple, or it goes by a title when it is for nobody in particular: a family’s recipes, a class’s year, a teamget_linksReturns the link to forward to contributors, the link that plays every message straight through, and a short message the organiser can paste alongside.add_peopleRecords who is expected to record. A person with an email address can be emailed the invitation and the reminders; a person with only a name is reached in a group chat, and the reminder message names them. Adding a person sends nothing.send_it_outEmails the invitation once to every person added with an address, and returns a tap that opens WhatsApp, a text or a mail draft with the message and the link already written, for the family group and for anyone with no address. Nobody gets the invitation twice, and each caller hachase_the_missingWorks out who is still out, emails a reminder to the ones with an address, and hands back a message naming them, ready for the group chat and ready for one person. A person gets at most one reminder a day and three in all, and never one after they have said stop.book_statusReturns who is in with their name and relationship, how many voices, videos and written messages have come in, how many carried a photo, who the organiser is still waiting on, the days left before collecting stops, and next: the day to chase the ones still out and the day to closfind_my_bookGiven the email address a book belongs to, Chorus emails that address a six digit code and returns nothing about the books. Given the address and the code, it returns every book on that account with its handle. Holding the mailbox is the proof, so a book cannot be found by guessichange_the_bookChanges the settings the organiser can change on the site: the day collecting stops, the questions people answer, whether they may send voice, video or writing, which one the button offers first, and whether the people recording are offered to chip in towards the printed book. Noget_styleReads the book’s style file: every part of a person’s page, with its size, place, typeface, colour and alignment, what each part means, the limits the print rules keep, and the people who have pages.set_styleChanges any line of the book’s style file, for every page or for one person, and returns what was set, what a print rule changed with its reason, what was refused with its reason, and pictures of the pages as they now print. A path is a part and a property, such as codes.size_mm,preview_pagesReturns pictures of the spreads the book prints, laid out by the same code that makes the printer’s file: a page by its number, a person’s first page, or the first message when neither is given.arrange_the_bookSets the order the people print in, takes a person’s pages out or puts them back, and changes the book’s title and its cover: a photo or one of six colours on the front, the line under the title, and what the back carries. It moves pages and changes no word on them, and a person’their_own_linkReturns the second link, which puts questions to the person the book is for about their own life. It refuses on a memorial, a new baby and an as they grow book, where the person cannot answer. The link is for that one person, and a group chat gets the collecting link.read_the_messagesReturns every message with who left it and what they said. A written message reads back whatever was paid; a voice or a video is written out on the tier that includes the words, and where it is not, the tool says so rather than half-answering.close_collectingStops new messages arriving and returns the final counts with the gift link. Nothing is deleted and nothing is finished; it can be reopened.reopen_collectingReopens a book that was closed or whose date ran out, and returns the collecting link to send round again.orderReturns a payment link for one of the three ways to keep the book: voices, book, or keepsake, which is the printed hardcover. The price is on Stripe’s page, which takes the card and, on the keepsake, the postal address. This tool never takes a card and never names a price.order_statusReturns whether the book has been paid for and which option was bought, and on a printed one the stage the printer is at with the tracking.send_feedbackSends a short note to the people who make Chorus about a tool that failed or returned something unexpected, a request no tool covers, or a description that was unclear. Email addresses and phone numbers are taken out before the note is kept.
