Chorus MCP server

Which MCP servers are Chorus's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry namecom.choruskeepsake/chorusverified in the MCP registry

The registry name sits under choruskeepsake.com. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-24 the server answered initialize and tools/list without a sign-in. First answer in 336 ms.

Should an agent connect itNot proven either way yet
  • Its tools do every use case we checked: send one link so everyone can add a message; turn recorded messages into a printed hardcover book.
  • Checked on 3 of the 7 days it takes to judge reliability.

Once connected

  • For "send one link so everyone can add a message", the likely first call is start_book.
  • add_people, send_it_out change data without a sign-in: anyone with the address can call them.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

  • Tools that change data, on a server that answers without a sign-in: add_people, send_it_out

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

Tools it offers14 tools · read 2026-10-24
  • start_book

    Starts a book of voice, video and written messages and returns the single link the organiser sends to everyone taking part. The book is for one person or a couple, or it is called by a title when it is for nobody in particular: a family’s…

  • get_links

    Returns the link to forward to contributors, the link that plays every message straight through, and a short message the organiser can paste alongside.

  • add_people

    Records who is expected to record. Somebody with an email address can be written to by send_it_out and reminded by chase_the_missing; somebody with only a name is reached in a group chat and their name is what the chase reads out. Adding…

  • send_it_out

    Emails the invitation once to every person added with an address, and hands back 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…

  • chase_the_missing

    Works 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…

  • book_status

    Returns who is in with their name and relationship, how many voices, videos and written messages have landed, how many carried a photo, who the organiser is still waiting on, and the days left before collecting stops.

  • find_my_book

    Call it with the email address the book belongs to and Chorus sends that address a six digit code, returning nothing about the books. Call it again with the address and the code and it hands back every book on that account with its…

  • change_the_book

    Changes the settings the organiser can change on the site: the day collecting stops, the questions people are asked, whether they may send voice, video or writing, and which one the button offers first. Nobody is told about a change.

  • their_own_link

    Returns the second link, which asks the person the book is for about their own life rather than about somebody else. It refuses on a memorial, a new baby and an as they grow book, where the person cannot answer, and it is never the link…

  • read_the_messages

    Returns 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…

  • close_collecting

    Stops new messages arriving and returns the final counts with the gift link. Nothing is deleted and nothing is finished; it can be reopened.

  • reopen_collecting

    Reopens a book that was closed or whose date ran out, and returns the collecting link to send round again.

  • order

    Returns a payment link for one of the three ways to keep the book: voices, book, or keepsake, which is the printed hardcover. Stripe shows the price and takes the card and, on the keepsake, the postal address. This tool never takes a card…

  • order_status

    Returns 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.

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "chorus": {
      "type": "http",
      "url": "https://choruskeepsake.com/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http choruskeepsake https://choruskeepsake.com/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://choruskeepsake.com/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
