Setup

Prerequisites

• A Stripe account with test mode enabled
• Node.js and npm installed
• Claude Desktop or another MCP-compatible client

Installation

No installation is required! You can use this MCP server directly with npx:

npx stripe-test-mcp

This will automatically download and run the latest version of the server.

Configuration

Environment Variables

Set your Stripe test API key as an environment variable:

export STRIPE_API_KEY=sk_test_your_test_key_here

Important: Only test keys are allowed. The server will reject live API keys for security.

Usage Examples

Time-based Subscription Testing

• Create a test clock:

  Use create_stripe_test_clock with frozen_time: 1704067200 (Jan 1, 2024)
  

• Create customers associated with the test clock:

  Use create_stripe_test_customers with test_clock: clock_id_from_step_1
  

• Create subscriptions for the customers:

  Use create_stripe_test_subscription with customer IDs and subscription items
  

• Advance time to trigger billing:

  Use advance_stripe_test_clock to move forward by billing cycle periods
  

Clean Up Test Data

• Delete test customers:

  Use delete_stripe_test_customers with customer IDs
  

• Archive test products:

  Use archive_stripe_test_products with product IDs or URLs
  

Development

Local Development

If you want to contribute or modify the server locally:

• Clone the repository:

git clone <repository-url>
cd stripe-testing-tools

• Install dependencies:

npm install

• Build the server:

npm run build

• For development with auto-rebuild:

npm run watch

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. Use the MCP Inspector:

npm run inspector

The Inspector provides a web interface for testing and debugging MCP tools.

Security

• Only Stripe test API keys are accepted
• Live API keys are rejected to prevent accidental charges
• All operations are performed in Stripe's test mode

Error Handling

• Missing API keys will throw descriptive error messages
• Live API keys are blocked with security warnings
• Test clock customer limits are enforced (max 3 customers per clock)
• Invalid parameters are validated using Zod schemas
