Fast, Low-Token Browser Automation
uBrowser is a high-performance automation skill designed for developers who need to control web browsers without the token bloat of standard LLM-web interactions. It solves the "chatty" nature of AI automation by batching multiple actions—like navigating, typing, and clicking—into a single execution window, significantly reducing latency and cost.
What it does
Instead of the AI thinking after every single click, uBrowser allows for browser_batch execution. It handles complex multi-step workflows like logging into dashboards, filling out multi-page forms, and scraping data behind authentication walls. It uses compact snapshots to provide the AI with a lightweight representation of the DOM, focusing only on interactive elements to stay within context limits.
Supported Capabilities
- Persistent Sessions: Maintain logins across different runs using local profile directories.
- Network/Console Inspection: Debug AJAX failures and JS errors directly from the agent.
- Intelligent Extraction: Pull structured data, tables, and links into clean JSON formats.
- Compact Snapshots: 70% smaller payloads compared to full DOM traces.
Why it's better than standard prompting
Most AI agents fail at web tasks because they get lost in large HTML files or run out of tokens during long flows. uBrowser provides a specialized MCP layer that optimizes the "vision" of the AI, making it faster, cheaper, and far more reliable for production-grade scraping and testing.
