onyx_browser_eval
InactiveTool of onyx-paid-mcp
Evaluate a JavaScript expression on the current CDP-controlled Chrome page and return the result by value. Use as a power-tool when the specific click/extract/type tools don't fit — pull deeply nested DOM data, dispatch synthetic events, read computed styles. Demo mode echoes the expression length without executing. (price: $0.004 USDC, tier: metered)
