Hey 👋 Solo dev (Jitendra & Kapil) from Indore. Just shipped V0 of an open-source MCP server for AI agents to safely issue refunds. Why we built it: Every team building AI customer support hits the same wall — agents can suggest refunds but can't safely execute them. Network retries → double charges. No audit. No kill switch. Every team rebuilds the same broken safety layer. What V0 has: ✓ Single MCP/HTTP endpoint for AI agents ✓ Built-in idempotency (same request_id never refunds twice) ✓ Kill switch (disable all refunds with one env var) ✓ Append-only audit log ✓ Sandbox-only — production keys rejected at startup V0 is Razorpay test mode. Stripe + Paddle are coming in V1 (2-3 weeks). 10-second taste, no setup needed: curl -X POST https://web-production-60b12.up.railway.app/demo/issue_refund \ -H "Content-Type: application/json" \ -d '{"payment_id":"pay_TEST","amount":1500,"request_id":"my-test","reason":"trying"}' Run twice — duplicate gets blocked at our layer. That's the safety in 5 seconds. Repo (MIT): https://github.com/jiten-github78/mcp-refund-v0 Looking for early feedback. Roast it. What's missing? What would make you actually use it in production?
