unified-pay-cli
This server is a payment gateway CLI and MCP server that lets you create payment links, manage transactions and refunds, verify webhooks, and analyze payments across Stripe, Razorpay, and LemonSqueezy.
Create payment and checkout links (single or itemized invoices) with custom amounts, currencies, descriptions, customer details, expiry, and tax breakdowns.
Inspect transactions – list recent charges and check payment status for a given ID.
Issue refunds – partial or full refunds for a payment ID across supported providers.
Verify webhook signatures – authenticate HMAC-SHA256 signed Stripe/Razorpay payloads.
Trigger mock webhooks – simulate signed events (e.g., payment.captured, payment.failed) to test local endpoints.
Get payment analytics – retrieve revenue, success rates, and performance across gateways.
Manage provider configuration via CLI credentials (Stripe, Razorpay, LemonSqueezy).
Run as an MCP server – expose tools (create_payment_link, list_transactions, get_payment_status, create_refund, verify_webhook_signature, etc.) to AI assistants like Claude, Cursor, or Copilot.
Provides tools for creating payment links, listing and inspecting transactions, issuing and tracking refunds, and verifying webhook signatures.

💳 unified-pay-cli
The Universal Payment Gateway CLI & Model Context Protocol (MCP) Server for Stripe, Razorpay & LemonSqueezy.
🚀 Highlights
⚡ Zero Installation Required: Run instantly on demand via
npx unified-pay-cli.🎯 Multi-Provider Engine: Standardized interface across Stripe, Razorpay, and LemonSqueezy.
🛠️ Smart Payment Link Generation: Interactive terminal UI prompts or direct scripted CLI flags.
🔄 Full Transaction & Refund Lifecycle: Live status checks, recent transaction listings, partial/full refunds, and dedicated refund progress tracking.
📡 Webhook Station & Forwarding Proxy: Built-in HTTP listener (
pay listen) that intercepts, color-codes, and forwards webhook events directly to your local backend (--forward http://localhost:3000/api/webhooks).🔒 Cryptographic Signature Verification: Built-in HMAC-SHA256 verification (
--secret) protecting your local development from forged or tampered webhook payloads.🤖 Native Model Context Protocol (MCP): Connect your payment stack to GitHub Copilot, Cursor, or Claude Desktop so AI can create links, verify signatures, and track invoices from natural language prompts.

⚡ Quick Start
1. Installation
Install globally or run on demand via npx:
# Global install (recommended for daily CLI use)
npm install -g unified-pay-cli
# Or run instantly with npx
npx unified-pay-cli --help2. Configure Credentials
# Stripe
pay config --stripe-key sk_test_51...
# Razorpay
pay config --razorpay-id rzp_test_... --razorpay-secret ...
# LemonSqueezy (Optional)
pay config --lemonsqueezy-key lms_... --lemonsqueezy-store 12345💻 CLI Command Reference
1. Create Payment Links (pay link)
# Interactive mode (prompts for provider, amount, description)
pay link
# Scriptable flag mode
pay link --provider razorpay --amount 350000 --currency INR --desc "2-Hour Technical Consultation"
pay link --provider stripe --amount 2500 --currency USD --desc "Pro Tier Subscription"2. Inspect Transactions (pay txn)
# List recent transactions
pay txn list --provider razorpay --limit 5
# Check specific payment details
pay txn status pay_Oq7Jk8LmNx9 --provider razorpay3. Issue & Track Refunds (pay refund)
pay handles the separate lifecycle of charges vs. refund entities:
# Issue a refund (full or partial in minor units)
pay refund create pay_Oq7Jk8LmNx9 --provider razorpay --amount 10000
# Track live refund progression
pay refund status rfnd_TRNTRFvhQ6NDKx --provider razorpay
# List all past refunds
pay refund list --provider razorpay4. Webhook Station, Verification & Proxy (pay listen)
Catch real-time webhook events during local development without complex tunneling setups:
# 1. Basic listener
pay listen --port 4242
# 2. Listener with HMAC-SHA256 signature verification
pay listen --port 4242 --secret my_webhook_signing_secret
# 3. Listener with signature verification + proxy forwarding to local backend
pay listen --port 4242 --secret my_webhook_secret --forward http://localhost:3000/api/webhooks🤖 Model Context Protocol (MCP) Integration
Turn your AI assistant into an autonomous billing and payment operator.
