LeServiteur
An MCP server that drives Chrome and the native desktop — An enriched fork of chrome-devtools-mcp (upstream history merged up to v1.3.0) that gives your AI agents full control of a Chrome browser and, beyond it, the native desktop — under a single policy and audit plane.
LeServiteur
Browser & desktop automation
- Works with MCP code agents (Claude, Cursor, Copilot, Antigravity)
- Multi-OS: X11, Wayland and Windows (UI Automation), with a dedicated installer
- Accessibility -> vision -> pixel routing to target elements
What LeServiteur does
Full Chrome DevTools
Performance traces, network and console inspection, memory snapshots, screencast, Lighthouse, light mode and WebMCP — the entire upstream toolset.
Video recording
start_recording, stop_recording, record_clip and get_recording_status. CDP screencast capture with ffmpeg encoding instructions.
Visual regression testing
save_baseline, visual_diff, check_regression: pixel-by-pixel comparison against stored baselines, with pass/fail verdict and a diff image.
56 native desktop tools
The desktop_* tools drive the real desktop over X11: screen and window capture, change monitoring via XDamage, native XTest input (click, type, drag).
Vision-driven control
desktop_act for a one-off action, desktop_agent for an autonomous loop driven by a vision model, targeting the active window by default.
Live streaming
MJPEG or h264-NVENC desktop stream, plus recording and visual regression applied to native apps, not just the browser.
