# Carbon Voice — AI Connector Carbon Voice publishes 28 MCP tools to Claude. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/communication/carbon-voice/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Communication](https://node8.ai/ai-connectors/communication/) # Carbon Voice Search and dictate against a Carbon Voice memo archive Listed in Claude · 28 published tools · Community-listed [Claude connector docs](https://getcarbon.app/mcp) [getcarbon.app](https://getcarbon.app/) 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. ### Who it is for People who capture thinking by voice and later need to retrieve it. ### 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. Availability ## 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. Publisher Phonon X, Inc. Verification Community-listed (61.5% of the Claude directory) Filed under Communication Endpoint `https://mcp.carbonvoice.app/` Documentation [Publisher setup docs](https://getcarbon.app/mcp) Published tools 28 · 21-50 tools band Depth rank in Communication 10 of 29 Snapshot August 2026 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. Quoted from the connector's own Claude directory listing as captured in August 2026. Node8 did not write it and does not vouch for it.
