# Circleback — AI Connector Circleback publishes 9 MCP tools to Claude and is listed in the ChatGPT apps directory. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/communication/circleback/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Communication](https://node8.ai/ai-connectors/communication/) # Circleback Retrieves meeting notes, transcripts, and action items Listed in ChatGPT and Claude · 9 published tools · Verified partner [ChatGPT listing](https://chatgpt.com/plugins/circleback?open_in_app) [Claude connector docs](https://circleback.ai/docs/mcp) [circleback.ai](https://circleback.ai) Overview ## What Circleback does Circleback is a notetaker that sits on meetings, transcribes them, writes up notes, and pulls out action items. Beyond the notes themselves, it supports automations that extract specified information from each meeting and push it into other systems such as a CRM, an issue tracker, or Slack. The ChatGPT app is the retrieval side of that. It searches and returns context from meeting notes and transcripts, calendar entries, action items, people and company records, support articles, and email threads from connected accounts. Questions can span everything a team has recorded rather than a single meeting, which is how the product describes itself as an organizational memory. ### Who it is for Teams that record their meetings in Circleback and want that history queryable alongside email and calendar context. ### What stands out Retrieval reaches past transcripts into calendar events, contacts, support articles, and connected email. Availability ## Where Circleback is listed Circleback ships this on both marketplaces: Circleback is listed in the Claude connectors directory and in the ChatGPT apps directory, under the same publisher domain. Only 392 of the 3,150 products in this directory are listed in both marketplaces. One MCP server can serve both surfaces; what differs is each platform's listing and review process. ChatGPT listing ## In the ChatGPT apps directory Developer Circleback AI, Inc. Filed under Productivity Listed since May 2026 Authentication Authenticates when installed Website [circleback.ai](https://circleback.ai) Policies published Privacy policy · Terms of service Official listing [Open in ChatGPT](https://chatgpt.com/plugins/circleback?open_in_app) Snapshot August 2026 Claude listing ## In the Claude connectors directory Circleback publishes 9 tools to Claude. That is a mid-sized surface: 41.3% of the 1,253 Claude-listed connectors expose fewer. The median Claude-listed connector filed under Communication publishes 11, so this one sits 2 tools below its bucket's median, 19th of 29. It falls in the 7-10 tools band, which holds 14.6% of the Claude directory. Circleback 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 Circleback Verification Verified partner (37.8% of the Claude directory) Filed under Communication Endpoint `https://circleback.ai/api/mcp` Documentation [Publisher setup docs](https://circleback.ai/docs/mcp) Published tools 9 · 7-10 tools band Depth rank in Communication 19 of 29 Snapshot August 2026 Circleback carries partner verification in the Claude directory, which 474 of 1,253 listings do (37.8%). That is a review step past self-publishing, not an Anthropic-built server. In the publisher's words ## How Circleback describes it > Bring context from Circleback into Claude.
