browser-devtools-mcp

The browser-devtools-mcp skill enables integration with browser automation and Chrome DevTools through the Model Context Protocol (MCP). It is designed to support live UI inspection, screenshot-based analysis, and visual debugging by connecting language models to running browser environments. This approach allows direct observation of real interfaces, making it possible to analyze layouts, styles, and rendering behavior in context rather than relying solely on static code.

The skill highlights capabilities such as capturing screenshots of live pages, extracting accessibility snapshots, inspecting CSS and computed styles, interacting with page elements, navigating between pages, resizing the browser viewport, and performing evaluations within the browser context. It supports workflows like screenshot-to-code conversion, visual regression testing, design token extraction, and debugging layout issues with immediate visual feedback. Through MCP’s standardized interface and stateful sessions, these interactions can be managed consistently while maintaining controlled permissions.

This skill is intended for developers, engineers, designers, and automation specialists who work on user interfaces and need reliable tools for bridging design and implementation. It is particularly useful in scenarios involving UI validation, automated visual testing, rapid prototyping, and iterative interface development where direct browser-level feedback improves accuracy and efficiency.
