Documented steps
Host behind a stable HTTPS endpoint with dependable TLS; local or testing endpoints are rejected at submission.
Ensure the `/mcp` endpoint supports low-latency streaming, long-lived requests, and server-sent events, and returns appropriate HTTP status codes.
Pick hosting accordingly: Vercel (preview environments, automatic HTTPS), Fly.io / Render / Railway (automatic TLS, streaming), Google Cloud Run or Azure Container Apps (scale-to-zero), or Kubernetes with SSE-capable ingress.
Store API keys and OAuth client secrets in the platform's secret manager and inject them as environment variables — never in the repository.
Instrument observability: log tool-call IDs, request latency, and error payloads, and monitor CPU, memory, and request counts.
Redact PII before writing logs — store correlation IDs rather than raw prompt text.
Verify auth and storage configuration against the production environment, then re-test in developer mode against the production URL before broad release.

Known gotchas
Plain request/response static hosting is insufficient — the `/mcp` endpoint must support streaming/SSE and long-lived connections.
Scale-to-zero platforms add cold-start latency to the first tool call of a session, which reads to users as the app hanging; pre-warm or budget for it.
Submission requires a publicly accessible domain with a defined CSP; tunnels and testing endpoints will not pass review.
