This gateway has no owner password yet. In the Cloudflare dashboard open this Worker, then Settings → Variables and Secrets, add a secret named OWNER_PASSWORD with a long random value, and reload this page.
Add a secret to this Worker named ACCOUNT_<SERVICE>_<ACCOUNT> holding the account's API key, for example ACCOUNT_RESEND_WORK. Built in: linear, resend. Any other MCP server that takes an API key works with a SERVICE_<NAME>_URL variable. Docs.
