- No malware found by supply-chain analysis.Pass
- Only part of the dependency tree could be resolved (123 of 127), so this covers what we could see, not the whole tree.Partial
- No install/post-install scripts declared.Pass

analyze_churn Analyze Churn ~92
Analyze customer cancellation feedback to identify churn patterns, severity, and actionable recommendations. Paste raw feedback text (one response per line) or CSV data.
| Name | Type | Req | Description |
|---|---|---|---|
| feedback | string | yes | Raw cancellation feedback. One response per line. Example: Too expensive Missing features we need Switched to competitor |
| focus | string | — | Optional focus area to narrow the analysis (e.g., 'pricing', 'onboarding') |
No output schema declared.
No examples provided.
analyze_sql_churn Analyze Churn from SQL Database ~206
Pull canceled subscriptions directly from a Postgres or MySQL database and analyze them for churn patterns. Requires POSTGRES_URL or MYSQL_URL env var (use a read-only database user , see retentioncheck.com/integrations for the exact SQL to create one). You describe your schema in plain arguments (table, cancelled_at_column, reason_column, etc.) and the tool generates a safe parameterized SELECT query. Includes plan MRR, sub age, and schema-mismatch detection with actionable errors. Defaults to last 90 days.
| Name | Type | Req | Description |
|---|---|---|---|
| dialect | string | yes | Which SQL dialect. Reads POSTGRES_URL or MYSQL_URL from env accordingly. |
| focus | string | — | Optional focus area to narrow the analysis (e.g., 'pricing', 'onboarding'). |
| lookback_days | integer | — | How many days back to analyze. Defaults to 90. Min 7. Max 365. |
| schema | object | yes | Schema mapping that tells the tool which columns hold what. |
No output schema declared.
No examples provided.
analyze_stripe_churn Analyze Stripe Churn ~127
Pull canceled subscriptions directly from Stripe and analyze them for churn patterns. Requires STRIPE_SECRET_KEY env var (use a restricted read-only key with Subscriptions, Customers, and Prices read access). Includes plan, MRR, sub age, and voluntary/involuntary context for each cancellation. Defaults to last 90 days.
| Name | Type | Req | Description |

get_example_analysis Example Churn Analysis ~62
See an example churn analysis to understand what RetentionCheck produces. Returns a pre-computed analysis , no API key required.
| Name | Type | Req | Description |
|---|---|---|---|
| scenario | string | — | Which example scenario to show. Options: b2b-saas (default), consumer-app, pricing |
