Features

Time Simulation Tools

• Test Clock Management - Create and advance Stripe test clocks for time-based testing
• Subscription Testing - Test billing cycles and subscription renewals by controlling time

Customer Management

• Bulk Customer Creation - Create multiple test customers with customizable properties
• Customer Cleanup - Delete test customers to maintain clean test environments
• Test Clock Association - Link customers to test clocks for time-controlled testing

Product Management

• Product Archiving - Archive test products by ID or URL
• Product Deletion - Permanently delete test products to clean up test data

Subscription Testing

• Test Subscription Creation - Create subscriptions with configurable proration behavior
• Time-based Testing - Test subscription billing cycles using test clocks

Setup

Prerequisites

1. A Stripe account with test mode enabled
2. Node.js and npm installed
3. 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.

MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "stripe-test-mcp": {
      "command": "npx",
      "args": ["stripe-test-mcp"],
      "env": {
        "STRIPE_API_KEY": "sk_test_your_test_key_here"
      }
    }
  }
}

Usage Examples

Time-based Subscription Testing

1. Create a test clock:

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

2. Create customers associated with the test clock:

   Use create_stripe_test_customers with test_clock: clock_id_from_step_1
   

3. Create subscriptions for the customers:

   Use create_stripe_test_subscription with customer IDs and subscription items
   

4. Advance time to trigger billing:

   Use advance_stripe_test_clock to move forward by billing cycle periods
   

Clean Up Test Data

1. Delete test customers:

   Use delete_stripe_test_customers with customer IDs
   

2. 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:

1. Clone the repository:

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

2. Install dependencies:

npm install

3. Build the server:

npm run build

4. 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
