Domain policies in Stagehand 3.7

Stagehand 3.7.0 is live.

Use setDomainPolicy() to allowlist or blocklist the domains your agent can visit. Stagehand automatically closes any popup that tries to violate the policy.

await stagehand.context.setDomainPolicy({
  allowedDomains: ["www.browserbase.com"],
});
