MCP Server Overview
The retain-so/mcp-server MCP server connects AI agents to Retain's customer analytics and churn-prevention platform. It translates MCP tool calls into HTTP requests against Retain's public agent API, providing read access to risk, customer, alert, and churn data. With a read-and-write agent key, it can also mark alerts as contacted or archive resolved alerts. Use it when an MCP client needs Retain data or limited retention workflow actions without opening the Retain dashboard.
- Identify customers at critical or high churn risk
- Review MRR exposure from active churn alerts
- Inspect a customer's full Retain health profile
- Summarize churn and net revenue retention metrics
