## MCP tools (4)

### `analyze_churn` (~92 tokens)

Analyze Churn

Analyze customer cancellation feedback to identify churn patterns, severity, and actionable recommendations. Paste raw feedback text (one response per line) or CSV data.

Input parameters:

- `feedback` (string, required): 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')

### `analyze_stripe_churn` (~127 tokens)

Analyze Stripe Churn

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.

Input parameters:

- `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.

### `analyze_sql_churn` (~206 tokens)

Analyze Churn from SQL Database

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.

Input parameters:

- `dialect` (string, required): 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, required): Schema mapping that tells the tool which columns hold what.

### `get_example_analysis` (~62 tokens)

Example Churn Analysis

See an example churn analysis to understand what RetentionCheck produces. Returns a pre-computed analysis ,  no API key required.

Input parameters:

- `scenario` (string): Which example scenario to show. Options: b2b-saas (default), consumer-app, pricing
