Environment

Name	Required	Notes
ANTHROPIC_API_KEY	No	Anthropic API key for running churn analysis (required for analyze_churn, analyze_stripe_churn, and analyze_sql_churn; get_example_analysis works without it). Secret.
STRIPE_SECRET_KEY	No	Stripe API key for analyze_stripe_churn. Use a RESTRICTED (read-only) key with these permissions: Subscriptions Read, Customers Read, Prices Read. Create one at https://dashboard.stripe.com/apikeys/create. Optional — only required for the analyze_stripe_churn tool. Secret.
POSTGRES_URL	No	Postgres connection string for analyze_sql_churn when dialect='postgres'. Format: postgres://user:pass@host:5432/db?sslmode=require. Use a READ-ONLY user — see retentioncheck.com/integrations for the exact GRANT SQL. Optional — only required for the analyze_sql_churn tool with postgres dialect. Secret.
MYSQL_URL	No	MySQL connection string for analyze_sql_churn when dialect='mysql'. Format: mysql://user:pass@host:3306/db?ssl=true. Use a READ-ONLY user — see retentioncheck.com/integrations for the exact GRANT SQL. Optional — only required for the analyze_sql_churn tool with mysql dialect. Secret.
RETENTIONCHECK_TELEMETRY	No	Set to 0 to opt out of anonymous usage telemetry. Telemetry tracks tool invocations and aggregate counts — never the feedback text, financial values, or any PII.
