Carbon Voice
Search and dictate against a Carbon Voice memo archive
Overview
What Carbon Voice does
Carbon Voice records spoken material: voice memos, conversations and direct messages. The connector makes that archive searchable, so a question about what was said in a given week can be answered, a long thread summarised, and a new memo dictated or a reply sent without leaving the conversation. Twenty-eight tools are published, a wide surface for a product whose vendor description runs to two sentences, which means the listing copy is a poor guide to what the connector actually reaches. Community tier, with documentation available. A Carbon Voice account holding the recordings is required.
Tool surface
The gap between a two-line description and twenty-eight claimed tools cannot be closed from outside, because the endpoint requires credentials before it will enumerate anything.

Where Carbon Voice is listed
Carbon Voice is listed in the Claude connectors directory only. Phonon X, Inc. has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one.
Claude listing
In the Claude connectors directory
Carbon Voice publishes 28 tools to Claude, deeper than 79.2% of the 1,253 Claude-listed connectors.
The median Claude-listed connector filed under Communication publishes 11, so this one runs 17 tools above its bucket's median and ranks 10th of 29 by tool count.
It falls in the 21-50 tools band, which holds 20% of the Claude directory.
Carbon Voice publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.
Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.

Carbon Voice is community-listed in the Claude directory, the tier 770 of 1,253 connectors sit in (61.5%). It is the default for a self-published server, and says nothing either way about quality.
In the publisher's words
How Phonon X, Inc. describes it
Carbon Voice captures the ideas you speak out loud: voice memos, conversations, and direct messages. Claude makes them searchable. Ask what was said last week, summarize a long thread, then dictate a new memo or send a reply without leaving the chat.
