Give Claude Sonnet 4 access to your churn feedback
ChurnWin exposes your Stripe churn metrics, cancellation feedback, at-risk customers, and retention action plan through a read-only MCP server. Add it to Claude Code or any Claude Sonnet 4 MCP client so your agent can answer: “what should we fix to reduce churn?”
Claude can read churn reasons, cancellation feedback, and ChurnWin's action plan before recommending product fixes.
Turn repeated churn themes into backlog-ready issues with evidence, acceptance criteria, and metrics to watch.
ChurnWin's v1 agent surface is read-only, so Claude can investigate without changing billing or customer data.
Copy-paste MCP config
Use this shape in your Claude MCP client configuration. Replace the placeholder with a key from Settings → Agent Access.

"churnwin": {
"url": "https://api.churnwin.com/mcp/",

}Keep the trailing slash on /mcp/ to avoid redirect issues in strict MCP clients.
Prompts that work well
Using ChurnWin, inspect churn reasons and cancellation feedback for the last 90 days. Rank themes by MRR impact and tell me the smallest product fixes to try first.
Create three GitHub issue drafts from ChurnWin churn feedback. Include evidence, acceptance criteria, and metrics to watch. Do not include customer emails, names, or raw Stripe IDs.
Claude gets context, not control
The ChurnWin MCP server is designed for safe agent analysis: read churn signals, synthesize themes, and draft action plans while leaving billing changes, customer outreach, and production deploys under human review.
