What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

• polar_list_organizations

  List the organisations the token can act for. Start here — most other tools take an organization_id. Polar: GET /v1/organizations/.

• polar_list_products

  List products, optionally filtered by archived state, recurrence or a text query. Polar: GET /v1/products/.

• polar_get_product

  Fetch a single product with its prices and attached benefits. Polar: GET /v1/products/{id}.

• polar_list_customers

  List customers, optionally by email or a text query. Polar: GET /v1/customers/.

• polar_get_customer

  Fetch a single customer by Polar id. Polar: GET /v1/customers/{id}.

• polar_get_customer_state

  Fetch everything about one customer in a single call — active subscriptions, granted benefits and entitlements. The best answer to 'what does this customer currently have?'. Polar: GET /v1/customers/{id}/state.

• polar_get_customer_state_by_external_id

  Same as polar_get_customer_state, but looked up by YOUR external id rather than Polar's — the usual path when you hold your own user id. Polar: GET /v1/customers/external/{external_id}/state.

• polar_list_orders

  List orders, filtered by customer, product, subscription, status or a date window. Polar: GET /v1/orders/.

• polar_get_order

  Fetch a single order with its line items, discount and tax. Polar: GET /v1/orders/{id}.

• polar_list_subscriptions

  List subscriptions, filtered by customer, product, status, active state or cancellation window. Polar: GET /v1/subscriptions/.

• polar_get_subscription

  Fetch a single subscription with its product, price and period. Polar: GET /v1/subscriptions/{id}.

• polar_get_metrics

  Fetch revenue and subscription metrics over a date range, bucketed by interval — orders, revenue, MRR, active subscriptions. Polar: GET /v1/metrics/.

• polar_list_benefits

  List benefits — the things a product grants, such as licence keys, file downloads or Discord roles. Polar: GET /v1/benefits/.

• polar_list_benefit_grants

  List who has been granted one benefit, and whether the grant is still active. Polar: GET /v1/benefits/{id}/grants.

• polar_list_discounts

  List discount codes and their redemption limits. Polar: GET /v1/discounts/.

• polar_list_meters

  List the usage meters that aggregate events into billable quantities. Polar: GET /v1/meters/.

• polar_get_meter_quantities

  Fetch the aggregated quantities a meter has recorded over a window — what usage-based billing will charge for. Polar: GET /v1/meters/{id}/quantities.

• polar_list_events

  List the raw usage events ingested for metering, filtered by customer, meter, name or time. Polar: GET /v1/events/.

• polar_list_webhook_deliveries

  List webhook delivery attempts with their HTTP results — the tool for 'why did my webhook not arrive?'. Polar: GET /v1/webhooks/deliveries.

• polar_list_webhook_endpoints

  List the configured webhook endpoints and their subscribed events. Polar: GET /v1/webhooks/endpoints.

• polar_redeliver_webhook_event

  Queue one webhook event for redelivery after your endpoint recovered. Polar: POST /v1/webhooks/events/{id}/redeliver.

• polar_create_refund

  Refund an order, in full or in part. This moves real money back to the customer. Polar: POST /v1/refunds/.

• polar_cancel_subscription

  Cancel a subscription at the end of its current period. The customer keeps access until then. Polar: PATCH /v1/subscriptions/{id}.

• polar_create_checkout_link
