  },
  {
    q: 'Do I need to write code?',
    a: 'No. You describe the tool in natural language. We generate the TypeScript server, run static checks, build a Docker image and deploy it to a public OAuth-protected URL.',
  },
  {
    q: 'Which clients work?',
    a: 'Claude Desktop, Cursor, ChatGPT Custom Connectors, VS Code Copilot, Continue.dev — anything that speaks the MCP spec.',
  },
  {
    q: 'How is auth handled?',
    a: 'Every generated server is an OAuth 2.1 Resource Server. Our control plane is the Authorization Server (PKCE + Dynamic Client Registration + Resource Indicators per RFC 8707).',
  },
  {
    q: 'Can I self-host?',
    a: 'Yes. The runner is a plain Docker container; the control plane is open to BYO Postgres + Redis. See the self-hosting guide in docs.',
  },
  {
    q: 'What about secrets?',
    a: 'AES-256-GCM at rest in Postgres, injected as environment variables into the runtime container. Never logged, never echoed back.',
  },
  {
    q: 'Cold starts?',
    a: 'No cold starts. Containers stay warm. Sub-50ms tool-call overhead on average for in-region requests.',
  },
  {
    q: 'Rate limits?',
    a: 'Default 100 requests/min/IP per tool. Configurable per server. Quota enforced at the Traefik layer before hitting your container.',
  },
  {
    q: 'How fast is generation?',
    a: 'Spec → image → live URL typically completes in 45-90 seconds.',
  },
  {
    q: 'Logs and metrics?',
    a: 'Live log streaming to the dashboard, structured tool-call metrics (P50/P95/P99 latency, error rate, per-tool throughput) — all retained for 30 days.',
  },
  {
    q: 'What if I cancel?',
    a: 'You can export the full TypeScript source of every server you built. No vendor lock-in.',
  },
  {
    q: 'Custom domain?',
    a: 'Pro plan and above. Add a CNAME, we provision Let’s Encrypt automatically.',
