New in MCP: action items, shareable voice memos, and smarter search

The Carbon Voice Team
Phonon X, Inc.

We've updated the Carbon Voice MCP server with a big batch of new capabilities, which means you can use Claude and ChatGPT to do more with Carbon Voice than ever before.

If you've already connected Carbon Voice to Claude or ChatGPT, the new capabilities are there automatically, with nothing to install or update. If you haven't connected yet, follow the setup instructions for Claude or ChatGPT, and you'll have all of it from the start.

Here's what's new.

✅ Turn conversations into to-dos, automatically​

Claude can now pull action items straight out of your voice memos and conversations, and manage them. They're the same action items you see in Notebook → Action Items, so anything your assistant creates or checks off is there in the app too.

Try:

  • "What action items came out of my last team huddle?"
  • "Pull the to-dos from that voice memo and add them to my list."
  • "What's still open on my plate this week?"
  • "Mark the budget review action item as done."

🎙️ Turn any text into a voice memo, in your own voice​

If you've cloned your voice in Carbon Voice, Claude and ChatGPT can generate a voice memo from written text and hand you a link to send, so you can fire off a personal-sounding message without recording anything.

Try:

  • "Create a Carbon Voice memo that says 'Running 10 minutes late, see you soon!' and give me a link I can share."
  • "Turn this paragraph into a voice memo in my voice and share it with the sales team."

🔗 Share a message with one line​

Generate a shareable link to any voice memo or message: public, restricted to specific people, or forwarded into another conversation.

Try:

  • "Create a shareable link to this voice memo."
  • "Forward this message to the Marketing conversation."
  • "Share this update with just Sarah and the design team."

📝 Get the gist without listening to everything​

Claude can summarize a whole conversation, not just one message.

Try:

  • "Summarize what I missed in the Product conversation today."
  • "Give me the TL;DR of this thread."
  • "What's the overall takeaway from this week's standups?"

🔍 Find messages faster​

New search covers listened and unlistened status, mentions, and labels, not just keywords.

Try:

  • "Show me messages I haven't listened to yet."
  • "Find anything where I was mentioned this week."
  • "Pull up everything tagged 'urgent' in the last few days."

The tools behind it​

If you like knowing what your assistant is actually calling, this is what it now has to work with.

Action items

  • suggest_action_items_from_message: pull the action items out of one message.
  • suggest_action_items_from_messages: do the same across several messages at once, catching commitments that span more than one.
  • list_my_action_items: everything assigned to you, plus what you created and haven't assigned.
  • list_action_items: the items in one conversation or folder.
  • get_action_item, create_action_item, update_action_item, delete_action_item.
  • set_action_item_status: move an item between suggested, to-do, and done.

Voice memos from text

  • create_voicememo_message: create a voice memo from text, spoken in your text-to-speech or cloned voice, or from an audio file.

Sharing and forwarding

  • create_message_share_link: a public link, one restricted to specific people or a workspace, or a forward onto another message.
  • get_message_share_link: look up a link you already created.

Summaries

  • summarize_conversation: run a summary AI Action over a conversation's recent messages.

Search and inbox

  • search_message_ids: filter by mention, label, sender, conversation, or whether you were notified.
  • search_messages_by_heard_status: listened or unlistened, with unheard counts per conversation.
  • list_inbox_notifications: your mentions, invites, and workspace activity.
