Retention Playbook

A human-guided MCP App for building and checking customer retention playbooks. It collects a retention brief, requires explicit in-app approval, validates six retention plays, and exports an approved playbook as Markdown or CSV.

Local development

npm ci --ignore-scripts
APPROVAL_HMAC_KEY="replace-with-at-least-32-random-characters" npm test
APPROVAL_HMAC_KEY="replace-with-at-least-32-random-characters" npm start

APPROVAL_HMAC_KEY signs brief approvals. Set it explicitly for local runs; production receives it from the deployment environment file.

The local server listens on port 8790 by default. Its MCP endpoint is /mcp, health endpoints are /health and /ready, and public product pages start at /.

Data boundary

The service is stateless and closed-world. It does not fetch URLs, change accounts, send messages, make outbound network requests during tool execution, or intentionally retain briefs and exports. It writes and checks text only and does not promise churn outcomes.
