Chrome DevTools and browser automation through MCP for live UI work: screenshots, DOM and computed-style inspection, screenshot-to-code, design token extraction, Lighthouse and accessibility audits, and visual regression checks. Use when Claude should look at a running interface instead of guessing from code.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Browser DevTools MCP Integration Leverage browser automation and DevTools through MCP (Model Context Protocol) for live UI inspection, screenshot-to-code workflows, and visual debugging. This skill enables direct observation and manipulation of running interfaces. --- ## When to Use This Skill - Capturing screenshots of live UIs for analysis - Inspecting CSS and computed styles programmatically - Implementing screenshot-to-code workflows - Debugging layout issues with visual feedback - Extracting design tokens from existing sites - Automating visual regression testing - Building live preview workflows --- ## MCP Architecture Overview ### What is MCP? Model Context Protocol (MCP) is Anthropic's standard for connecting LLMs to external tools. It provides: - **Standardized tool interface** - Consistent way to expose capabilities - **Bidirectional communication** - Tools can query the model - **Stateful sessions** - Maintain context across interactions - **Permission boundaries** - Control what tools can do ### Browser MCP Landscape ``` +-------------------+ +-------------------+ +-------------------+ …

How to install
mdr add hermeticormus/libreuiux-claude-code/browser-devtools-mcp@sha256:142fdff517b389f1The line at the top of this page pins the label git:20260930.9d3b6c4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
