What you can do with it

• Debug complex JavaScript code on a webpage using an AI agent.
• Analyze network requests and WebSocket communications for web scraping or security research.
• Bypass anti-bot measures on websites for automated data collection.

Verified live · 24 tools

We started this MCP server in an isolated sandbox and it exposed these tools:

• break_on_xhr

  Sets a URL-substring breakpoint for a future XHR/Fetch when runtime request arguments, local variables, or payload construction must be inspected. For an already captured request, call get_request_ini

• clear_network_requests

  Discard captured HTTP(S) evidence for the currently selected page after confirm=true. Use this immediately before reproducing an action when a clean network capture window is needed; do not use it to

• clear_site_data

  Irreversibly clear browser state after confirm=true to create a clean replay environment for the selected page. Use this before replaying login, session creation, storage initialization, or other stat

• click_element

  Performs one verified, auditable click in the currently selected frame. Use it when the task requires activating a known button, link, or control after selecting the correct page/frame and identifying

• evaluate_script

  Evaluates one focused JavaScript function for DOM/page state, web storage, page-defined globals, a paused-frame expression, or browser-side processing of one local file. Use it when those runtime valu

• get_paused_info

  Inspects the current call stack, source locations, and selected call-frame scopes after a code/XHR breakpoint or explicit pause has stopped execution. It neither creates a pause nor resumes one. Retur

• get_request_initiator

  Non-pausing first action for tracing which JavaScript initiated a retained HTTP request when CDP initiator evidence was active. Pass the reqid from list_network_requests; because initiator capture sta

• get_script_source

  Reads a small source region around a search match, paused location, or known statement without executing or pausing the page. Select by URL when available because URL-backed scripts can be resolved ag

• get_websocket_messages

  Inspect captured bidirectional WebSocket connections and frame payloads for the selected page. Use this for WebSocket, socket, live-update, push, streaming, or realtime message flows; use list_network

• list_breakpoints

  Inspects code and XHR/Fetch breakpoints managed by this MCP session before reproducing an action or cleaning up debugger state. Returns current code breakpointIds and the exact XHR URL patterns needed

• list_console_messages

  Inspects console messages and uncaught page errors captured for the selected page. Use it to diagnose runtime failures, warnings, application logs, or values already emitted by page code; use search_i

• list_network_requests

  Inspect captured HTTP(S) traffic for the currently selected page. Use this for API calls, request or response headers and bodies, redirects, authentication/session flows, replay or signing inputs, and

• list_scripts

  Discovers JavaScript currently loaded in the selected debugger context—the main frame by default, or the frame chosen with select_frame. Use select_frame first for iframe-specific source/debugger work

• navigate_page

  Navigates, reloads, or moves through history in the currently selected page. Use it to reproduce requests, trigger configured breakpoints, refresh scripts, or continue a workflow in the same tab; use

• new_page

  Opens a separate browser page for a URL, reusing an existing about:blank startup tab when available. Use this when the task needs another tab or should preserve the currently selected page; use naviga
