Tools Stripe exposes

STRIPE_ACCEPT_QUOTE

Accept quote

Tool to accept a quote in Stripe. Use when you need to accept a finalized quote, which will create an invoice, subscription, or subscription schedule based on the quote's configuration.

STRIPE_ACTIVATE_BILLING_ALERT

Activate billing alert

Reactivates a billing alert, allowing it to trigger again. Use when you need to resume monitoring usage thresholds and receiving notifications for a previously deactivated alert.

STRIPE_ADD_INVOICE_LINES

Add lines to invoice

Tool to add multiple line items to a draft Stripe invoice. Use when you need to add additional charges, services, or credits to an existing invoice that is still in draft status.

STRIPE_ADVANCE_TEST_CLOCK

Advance test clock

Advance a test clock to a future timestamp. Use for testing time-based billing scenarios. Requires test mode API keys (test_helpers endpoints are only available in test mode). The advancement is asynchronous; monitor the status field to track completion (status changes from 'advancing' to 'ready').

STRIPE_APPLY_CUSTOMER_BALANCE

Apply customer balance to payment intent

Manually reconciles remaining amount for a customer_balance PaymentIntent by applying funds from customer's cash balance. IMPORTANT: This action only works with PaymentIntents that have 'customer_balance' in their payment_method_types. The customer_balance payment method type must be enabled in your Stripe account settings. Use this when you need to apply funds from a customer's cash balance account to complete or partially fund a PaymentIntent.

STRIPE_ARCHIVE_BILLING_ALERT

Archive billing alert

Tool to archive a billing alert in Stripe, removing it from list views and APIs. Use when you need to permanently archive a billing alert. This action is non-reversible.

STRIPE_ATTACH_CUSTOMER_SOURCE

Attach source to customer

Attach a payment source (card token or source object) to a customer for future charges. IMPORTANT: This is a legacy API. For new integrations, use the PaymentMethods API instead (STRIPE_ATTACH_PAYMENT_METHOD). The source parameter accepts: - Card tokens (tok_xxxx) created client-side via Stripe.js or mobile SDKs - Source objects (src_xxxx) for alternative payment methods NOTE: PaymentMethod objects (pm_xxxx) cannot be used with this endpoint. Use STRIPE_ATTACH_PAYMENT_METHOD for those. In test mode, you can use test tokens like 'tok_visa'. In live mode, tokens must be created client-side for PCI compliance.

STRIPE_ATTACH_INVOICE_PAYMENT

Attach payment to invoice

Attaches a PaymentIntent or Out of Band Payment to an invoice's payments list. When the PaymentIntent status changes to succeeded, the payment is credited to the invoice. Use when you need to associate an existing payment with a specific invoice.

Events your agent can react to

STRIPE_CHARGE_FAILED_TRIGGER

Charge Failed Trigger

Triggered when a direct charge fails in Stripe's legacy Charges API

STRIPE_CHECKOUT_SESSION_COMPLETED_TRIGGER

Checkout Session Completed Trigger

Triggered when a checkout session is completed in Stripe

STRIPE_INVOICE_PAYMENT_SUCCEEDED_TRIGGER

Invoice Payment Succeeded Trigger

Triggered when an invoice payment is successful in Stripe

STRIPE_PAYMENT_FAILED_TRIGGER

Payment Intent Failed Trigger

STRIPE_PRODUCT_CREATED_TRIGGER
