Plug your AI into your churn.
ChurnWin collects cancellation feedback and churn signals from your Stripe customers. The developer API and MCP server let your AI agent read that data and tell you what to build or fix to reduce churn — without writing a single SQL query.
Two ways to connect
Both options use the same API key, scoped to your ChurnWin account.
Connect any MCP-compatible AI client (Claude, Cursor, Windsurf…) directly to ChurnWin. Your agent discovers all available tools automatically — no hand-written prompts needed.
MCP setup guideStandard JSON over HTTPS. Point any HTTP-capable agent at https://api.churnwin.com/api/v1/agent and start querying. A machine-readable OpenAPI spec is available too.
What your agent can read
All endpoints are read-only in v1. Your data never leaves ChurnWin — the API key only grants read access.

Who it's for
Indie SaaS founders
Drop your MCP config into Claude and ask it what's driving churn this month — no dashboard diving.
Developer-led teams
Pipe churn data into your own AI workflows, internal tools, or Slack bots via the REST API.
AI-native builders
Build agents that cross-reference churn feedback with your product roadmap and suggest what to ship next.
Authentication
Every request requires an Authorization: Bearer cwk_live_… header. Keys are minted — and revoked — from Settings → Agent Access. You need an active ChurnWin plan to create keys.
Read-only scope — API keys cannot modify or delete your data.
