Public x402 pay-per-call MCP server behind https://papacasper.com/mcp/.
Discovery documents
scripts/gen-discovery.ts generates openapi.json and .well-known/x402 from the live tool
registry (src/tools) and writes them into ../site/public/, since discovery crawlers probe the
domain root (papacasper.com/openapi.json), not /mcp/. Re-run it and redeploy the site
(~/dev/papacasper/site, ./scripts/deploy.sh) whenever a tool is added, removed, or repriced:

x402 protocol
Payments run on x402 v2 via @x402/hono, facilitated by https://facilitator.xpay.sh
(zero fees, gas-sponsored, no API key) on Base mainnet (eip155:8453). Configured through
X402_FACILITATOR_URL and X402_NETWORK env vars.
