[Tool] mcp-x402-gateway — wrap any MCP server with USDC + Stripe + license keys (no fork)

Just published v0.1.0 of `mcp-x402-gateway` — drop-in paywall layer for any stdio or HTTP MCP server.

**Three monetization paths in one package:**

- **x402 micropayments** — per-call USDC on Base via Coinbase CDP facilitator (zero protocol fee)

- **License keys** — HMAC-signed tokens for tiered access (Pro/Business/Enterprise)

- **Stripe fallback** — fiat subscriptions for non-crypto users

**Per-route pricing via JSON** — no code changes to your existing MCP.

```bash

npm install mcp-x402-gateway
