You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Create, update, list, get, and delete browser sessions, and read archived telemetry for active or deleted sessions. Supports headless/stealth modes, profiles, proxies, viewports, extensions, and SSH tunneling.
manage_profiles
Setup (with guided live browser session), search/list with pagination, get, and delete browser profiles for persisting cookies and logins.
manage_projects
Create, list, get, update, and delete organization projects. Inspect and update per-project resource limits.
manage_api_keys
Create, list, get, update, and delete org-wide or project-scoped API keys. Create returns the plaintext key once.
manage_browser_pools
Create, list, get, delete, and flush pools of pre-warmed browsers. Acquire and release browsers from pools.
Start, stop, and list MP4 video replay recordings for a browser session. Session-scoped: start once, run your automation, then stop. Requires a paid Kernel plan.
manage_extensions

manage_apps
List/search apps, invoke actions, get/list/delete deployments, and get invocation results.
manage_auth_connections
Create, list, get, delete, login, submit, and wait for managed-auth connections in every client. Use domain-filtered `list` for discovery. App-capable clients additionally receive `open_auth_login`; the programmatic actions remain available there too.
manage_credentials
Create, list, get, update, and delete stored credentials; fetch a current TOTP code for credentials with a configured totp_secret.
manage_credential_providers
