# StopChurn — AI Connector StopChurn publishes 31 MCP tools to Claude. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/sales-marketing/stopchurn/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Sales & Marketing](https://node8.ai/ai-connectors/sales-marketing/) # StopChurn Retention campaign drafting and sending through StopChurn Listed in Claude · 31 published tools · Community-listed [Claude connector docs](https://stopchurn.com/docs/integration/claude-connector/) [stopchurn.com](https://stopchurn.com/) Overview ## What StopChurn does StopChurn runs retention marketing across email, SMS, and WhatsApp: segments, broadcasts, and multi step journeys built on a customer base a business already has. The connector puts that workflow in the assistant, covering template generation as brand aware MJML carrying hosted images and coupon codes unique per recipient, audience groups defined by behavioural filters, broadcast drafting, scheduling, sending, and cancellation, and journey creation and activation. A brand book keeps voice and colours consistent across what gets generated. Authorisation runs OAuth 2.1 scoped to one client and brand, with separate read and write permission scopes over five functional areas. The listing states reads are unrestricted while anything capable of messaging customers begins as a draft needing explicit confirmation. ### Who it is for Retention marketers and agencies running lifecycle campaigns on StopChurn. ### Tool surface Thirty one tools are claimed across templates, audiences, broadcasts, journeys, and coupons, and the endpoint returns 401 rather than confirming any of it, which matches a server tied to one brand's customer list. Availability ## Where StopChurn is listed StopChurn is listed in the Claude connectors directory only. Stopchurn LTD 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 StopChurn publishes 31 tools to Claude, deeper than 81.4% of the 1,253 Claude-listed connectors. The median Claude-listed connector filed under Sales & Marketing publishes 18, so this one runs 13 tools above its bucket's median and ranks 31st of 94 by tool count. It falls in the 21-50 tools band, which holds 20% of the Claude directory. StopChurn 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 Stopchurn LTD Verification Community-listed (61.5% of the Claude directory) Filed under Sales & Marketing Endpoint `https://integrations.stopchurn.com/mcp` Documentation [Publisher setup docs](https://stopchurn.com/docs/integration/claude-connector/) Published tools 31 · 21-50 tools band Depth rank in Sales & Marketing 31 of 94 Snapshot August 2026 StopChurn 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 Stopchurn LTD describes it > StopChurn is a retention marketing platform that turns your existing customer base into repeat revenue with segmented, automated campaigns across email, SMS, and WhatsApp. This connector puts your whole retention workflow inside Claude. Instead of clicking through dashboards, just describe what you want: - "Draft a win-back email for customers who haven't purchased in 30 days" — Claude generates an on-brand MJML template from your brand book and shows you a pixel-accurate preview to iterate on. - "Create a segment of VIPs who spent over $500 this quarter" — build and update audience groups conversationally. - "Schedule this campaign for Tuesday 9am to the churn-risk segment" — draft, schedule, send, or cancel broadcasts. - "Set up a three-step onboarding journey for new signups" — create and activate automated lifecycle flows. - "How are our templates and recent campaigns organized?" — list and inspect templates, broadcasts, journeys, audiences, and coupons. What Claude can work with: - Templates: AI-generated, brand-aware email (MJML), with hosted images and per-recipient coupon codes - Audiences: customer groups with behavioral filters - Broadcasts: draft, schedule, send, cancel - Journeys: build and activate multi-step automations - Brand book: keep voice, colors, and guidelines consistent across everything Claude creates Built for safety: OAuth 2.1 authorization scoped to a single client and brand, with granular read/write permission scopes across five functional areas. Reads are unrestricted; anything that could message customers starts as a draft and requires explicit confirmation with audience acknowledgment before sending. Connecting alone never sends anything.
