TDQS
Scored across 23 tools
Most tools target distinct browser actions (click, type, hover, drag, drop, etc.), and descriptions clarify edge cases like snapshot vs screenshot. However, browser_drag vs browser_drop and browser_type vs browser_press_key could still cause occasional misselection without careful reading.
All tools share a consistent browser_ prefix and snake_case style, but the action part is mixed: verbs (browser_close, browser_evaluate) coexist with nouns (browser_snapshot, browser_network_requests, browser_tabs). This is readable but not a uniform verb_noun pattern.
23 tools is on the heavier side but justified for a full-featured browser automation server covering navigation, input, inspection, network, tabs, and dialogs. A few tools like browser_network_requests/request could arguably be merged, but the count is not excessive.
The toolset covers most core browser automation workflows, including navigation, clicking, typing, forms, screenshots, and network inspection. Minor gaps like dedicated checkbox/radio interaction or page reload are missing, but agents can work around them via browser_click or browser_evaluate.
