Scored across 35 tools
Most core browser and debugging tools are distinct (navigate, click, fill, evaluate), but there is notable overlap between lifecycle and state tools (stop_chrome vs close_instance, restart vs close, get_network_logs vs get_custom_events) and between stepping commands (step_over description incorrectly mentions 'step_over enters functions' while 'step_out' is mentioned but not defined). This ambiguity can cause agent misselection in edge cases.
Tool names mostly follow a consistent verb_noun pattern (open_tab, close_tab, list_tabs, set_breakpoint, resume, step_over). There are minor inconsistencies: 'webmcp_*' prefix is a different convention, and some verbs like 'restart', 'stop', 'close' create near-synonyms. Overall pattern is predictable and readable.
With 35 tools, the count is on the heavier side, but the server covers a broad scope: browser lifecycle, tab management, DOM interaction, debugging, performance, network, console, and experimental CDP. Most tools earn their place; a few like enable_proxy_auth and webmcp_* could be bundled, but none feel redundant.
The tool surface covers the full browser automation lifecycle (open/close instances and tabs, navigate, interact, inspect, debug, monitor performance, and network). Missing operations include no explicit 'step_out' despite being referenced, and limited screenshot options (no element-specific capture). Minor gaps that agents can work around with evaluate_js or send_cdp_command.
