Manual Client Operations Limit Browser Task Scale
When profile creation, launch, proxy configuration, and status checks depend on manual clicks, larger workflows become slower and harder to integrate.

More tasks lead to more repeated clicks
- 01
Profile Operations Stay Manual
Large profile sets require repeated opening, closing, and maintenance.
- 02
Scripts Lack One Integration Point
Without a standard local interface, systems need additional adapters.
- 03
Proxies and Groups Are Repeatedly Maintained
Profiles, groups, and proxies may be duplicated across tools.
- 04
Large Workflows Are Harder to Scale
UI-only management becomes inefficient as task volume grows.
Manage the Browser Workflow through One Local API
Expose profile, group, and proxy operations through a local interface for scripts and internal systems.

MasBrowser Skill and Local API Key require the Professional plan or above. Actions remain limited by team member permissions.
Local-Only Access with Controlled Permissions
The Local API listens only on 127.0.0.1 and does not directly expose itself to LAN or internet clients. API Key checks add another control layer.
Current Computer
MasBrowser ClientLocal API
127.0.0.1:30520API KeyExternal networks cannot connect directly
Localhost Only
The service listens on 127.0.0.1, so external networks cannot connect directly.
API Key Validation
When security validation is enabled, requests must provide a valid API Key.
Old Keys Become Invalid
Refreshing a key immediately revokes the previous key.
Team Permissions Apply
API actions inherit the signed-in desktop account and member permissions.
Credentials Removed on Disconnect
Skill credentials are stored for the current system user and removed when disconnected.
Local API in the MasBrowser Client
Start the desktop client to use the Local API locally, enable API Key validation, or connect the MasBrowser Skill.
API Entry
Open Local API from the API entry in the MasBrowser desktop client. No separate service deployment is required.
Less Manual Work, More Automation
Control profiles, proxies, and groups through one API and connect browser work to scripts, frameworks, and supported AI tools.
Make Browser Profiles Programmable
Turn browser profiles into local resources your system can schedule and control.
Profile Management
Control profile lifecycle through scripts.
Automation Frameworks
Retrieve debugging connections for existing scripts.
Internal Integration
Connect profile, proxy, and group management to internal workflows.
AI Skill

More Than an API: a Multi-Account Operations Workspace
Local API works with isolated profiles, proxies, groups, team collaboration, and automation in one anti-detect browser.
Isolated Browser Profiles
Give each task its own browser profile and configuration.
Unified Resource Management
Manage profiles, proxies, groups, and collaboration centrally.
Automation Connections
Connect scripts through local debugging interfaces.
Team Permission Boundaries
Keep actions within current account and member permissions.
