Chrome DevTools Adds a WebMCP Panel for Inspecting and Testing Page Tools

Chrome DevTools’ Application panel includes a WebMCP pane where developers can inspect the tools a page exposes to AI agents, review invocation history, and run tools manually. The panel helps check whether a tool’s registration, inputs, and behavior match what the developer intended. Chrome’s documentation describes a live list of available tools alongside a chronological log of invocations. Developers can inspect tool names and descriptions, filter calls by status or tool type, and run a tool with entered parameters—or reuse parameters from an earlier invocation.
