Working with Stripe MCP Server

Once set up, you can start interacting with the Stripe MCP Server through your AI assistant. Here are some practical examples of how to use it:

Creating a New Customer

Simply ask your AI assistant: "Create a new customer with email customer@example.com and name John Doe"

The AI will use the Stripe MCP Server to execute the customer_create function with the appropriate parameters.

Processing a Payment

To process a payment, you might say: "Create a payment intent for $50 in USD for customer John Doe"

This will trigger the payment_intent_create function with the specified amount, currency, and customer details.

Viewing Transaction History

To check recent transactions: "Show me the recent charges on our Stripe account"

This will invoke the charge_list function to retrieve transaction history.

Processing a Refund

When you need to issue a refund: "Process a refund for charge ch_123456789"

The AI will utilize the refund_create function to process the refund for the specified charge.

Integrating Stripe MCP Server in Development Workflows

The Stripe MCP Server can be integrated into various development workflows to enhance productivity and reduce the time spent on payment integration tasks.

Code Generation

When working with code editors that support AI, you can use the Stripe MCP Server to generate code snippets for Stripe integration:

"Generate JavaScript code to create a payment intent for $100"

The AI will provide code that correctly implements Stripe API patterns, saving you time and reducing the risk of implementation errors.

Documentation Assistance

When you need information about Stripe features:

"How do I implement Strong Customer Authentication in my Stripe integration?"

The AI can access Stripe documentation through the MCP server and provide detailed guidance tailored to your question.

Troubleshooting

For help with debugging issues:

"Why am I getting an 'invalid_request_error' when creating a payment intent?"

The AI can analyze common causes of the error and suggest solutions based on Stripe's best practices.
