What churnkey does

@churnkey/mcp is the Model Context Protocol package inside the churnkey/sdk repo. Point Claude, Cursor or another agent at it and the agent can query your Churnkey sessions, analytics and DSR records. The endpoint is https://mcp.churnkey.co/mcp over HTTP, so there is no local build step.

You need a Data API key. Without it the connection is there but the data calls fail. Grab the key from your Churnkey account; the same account hands out an appId if you want analytics.

The repo ships three packages: @churnkey/react for the cancel flow component on React 18 and 19, @churnkey/node for server-side token generation, and @churnkey/mcp for the server itself. MIT licensed.

What it helps with

check cancel sessions without opening the dashboard
pull retention numbers into a chat with the agent
locate open DSR requests in Churnkey
cross-check churn data while reviewing billing code
