TDQS
Scored across 42 tools
Many tools have overlapping purposes, such as browser_interact vs click_by_overlay_id/hover_by_overlay_id, browser_fill_form vs smart_fill_form, and several detection tools (popups, ads, captcha, login). The visual/interactive map tools also overlap heavily. Agents will struggle to choose the right tool.
Tool names mix snake_case (click_by_overlay_id, detect_popups) with camelCase (browser_navigate, browser_take_screenshot), and some use the 'browser_' prefix while others do not. There is no consistent verb_noun pattern, making the API feel chaotic.
42 tools is excessive for a browser automation server, especially when many could be consolidated (e.g., unified interaction tool, unified form tool, unified detection tool). The high count with redundancy suggests the set is not well-scoped.
The server covers a wide range of browser automation needs: navigation, interaction, forms, screenshots, popups, ads, captchas, cookies, storage, network, console, performance, tabs, windows, dialogs, and extensions. Minor gaps exist (e.g., explicit element selection or file upload tool, though browser_interact covers them), but overall the surface is quite comprehensive.
