Stripe Automation via Rube MCP

Automate Stripe payment operations through Composio's Stripe toolkit via Rube MCP.

Toolkit docs: composio.dev/toolkits/stripe

Prerequisites

• Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
• Active Stripe connection via RUBE_MANAGE_CONNECTIONS with toolkit stripe
• Always call RUBE_SEARCH_TOOLS first to get current tool schemas

Setup

Get Rube MCP: Add https://rube.app/mcp as an MCP server in your client configuration. No API keys needed — just add the endpoint and it works.

1. Verify Rube MCP is available by confirming RUBE_SEARCH_TOOLS responds
2. Call RUBE_MANAGE_CONNECTIONS with toolkit stripe
3. If connection is not ACTIVE, follow the returned auth link to complete Stripe connection
4. Confirm connection status shows ACTIVE before running any workflows

Core Workflows

1. Manage Customers

When to use: User wants to create, update, search, or list Stripe customers

Tool sequence:

1. STRIPE_SEARCH_CUSTOMERS - Search customers by email/name [Optional]
2. STRIPE_LIST_CUSTOMERS - List all customers [Optional]
3. STRIPE_CREATE_CUSTOMER - Create a new customer [Optional]
4. STRIPE_POST_CUSTOMERS_CUSTOMER - Update a customer [Optional]

Key parameters:

• email: Customer email
• name: Customer name
• description: Customer description
• metadata: Key-value metadata pairs
• customer: Customer ID for updates (e.g., 'cus_xxx')

Pitfalls:

• Stripe allows duplicate customers with the same email; search first to avoid duplicates
• Customer IDs start with 'cus_'

2. Manage Charges and Payments

When to use: User wants to create charges, payment intents, or view charge history

Tool sequence:

1. STRIPE_LIST_CHARGES - List charges with filters [Optional]
2. STRIPE_CREATE_PAYMENT_INTENT - Create a payment intent [Optional]
3. STRIPE_CONFIRM_PAYMENT_INTENT - Confirm a payment intent [Optional]
4. STRIPE_POST_CHARGES - Create a direct charge [Optional]
5. STRIPE_CAPTURE_CHARGE - Capture an authorized charge [Optional]

Key parameters:

• amount: Amount in smallest currency unit (e.g., cents for USD)
• currency: Three-letter ISO currency code (e.g., 'usd')
• customer: Customer ID
• payment_method: Payment method ID
• description: Charge description

Pitfalls:

• Amounts are in smallest currency unit (100 = $1.00 for USD)
• Currency codes must be lowercase (e.g., 'usd' not 'USD')
• Payment intents are the recommended flow over direct charges

3. Manage Subscriptions

When to use: User wants to create, list, update, or cancel subscriptions

Tool sequence:

1. STRIPE_LIST_SUBSCRIPTIONS - List subscriptions [Optional]
2. STRIPE_POST_CUSTOMERS_CUSTOMER_SUBSCRIPTIONS - Create subscription [Optional]
3. STRIPE_RETRIEVE_SUBSCRIPTION - Get subscription details [Optional]
4. STRIPE_UPDATE_SUBSCRIPTION - Modify subscription [Optional]

Key parameters:

• customer: Customer ID
• items: Array of price items (price_id and quantity)
• subscription: Subscription ID for retrieval/update (e.g., 'sub_xxx')

Pitfalls:

• Subscriptions require a valid customer with a payment method
• Price IDs (not product IDs) are used for subscription items
• Cancellation can be immediate or at period end

4. Manage Invoices

When to use: User wants to create, list, or search invoices

Tool sequence:

1. STRIPE_LIST_INVOICES - List invoices [Optional]
2. STRIPE_SEARCH_INVOICES - Search invoices [Optional]
3. STRIPE_CREATE_INVOICE - Create an invoice [Optional]

Key parameters:

• customer: Customer ID for invoice
• collection_method: 'charge_automatically' or 'send_invoice'
• days_until_due: Days until invoice is due

Pitfalls:

• Invoices auto-finalize by default; use auto_advance: false for draft invoices

5. Manage Products and Prices

When to use: User wants to list or search products and their pricing

Tool sequence:

1. STRIPE_LIST_PRODUCTS - List products [Optional]
2. STRIPE_SEARCH_PRODUCTS - Search products [Optional]
3. STRIPE_LIST_PRICES - List prices [Optional]
4. STRIPE_GET_PRICES_SEARCH - Search prices [Optional]

Key parameters:

• active: Filter by active/inactive status
• query: Search query for search endpoints

Pitfalls:

• Products and prices are separate objects; a product can have multiple prices
• Price IDs (e.g., 'price_xxx') are used for subscriptions and checkout

6. Handle Refunds

When to use: User wants to issue refunds on charges

Tool sequence:

1. STRIPE_LIST_REFUNDS - List refunds [Optional]
2. STRIPE_POST_CHARGES_CHARGE_REFUNDS - Create a refund [Optional]
3. STRIPE_CREATE_REFUND - Create refund via payment intent [Optional]

Key parameters:

• charge: Charge ID for refund
• amount: Partial refund amount (omit for full refund)
• reason: Refund reason ('duplicate', 'fraudulent', 'requested_by_customer')

Pitfalls:

• Refunds can take 5-10 business days to appear on customer statements
• Amount is in smallest currency unit

Common Patterns

Amount Formatting

Stripe uses smallest currency unit:

• USD: $10.50 = 1050 cents
• EUR: 10.50 = 1050 cents
• JPY: 1000 = 1000 (no decimals)

Pagination

• Use limit parameter (max 100)
• Check has_more in response
• Pass starting_after with last object ID for next page
• Continue until has_more is false

Known Pitfalls

Amount Units:

• Always use smallest currency unit (cents for USD/EUR)
• Zero-decimal currencies (JPY, KRW) use the amount directly

ID Prefixes:

• Customers: cus_, Charges: ch_, Subscriptions: sub_
• Invoices: in_, Products: prod_, Prices: price_
• Payment Intents: pi_, Refunds: re_
