Can't be undone 1Claude Code: ask
  • capture_contextReturns the structured representation of a web page: visible text with coordinates, interactive elements, forms and tables.No findings

    Why it is in this group

    • The name "capture_context" says "capture": a word that usually means money moves, which cannot be taken back.
    Description, as the server wrote it
    Returns the structured representation of a web page: visible text with coordinates, interactive elements, forms and tables. Use this to let an agent read and understand a page without parsing raw HTML.
Changes things 2Claude Code: ask
  • check_monitorTriggers an immediate check for a monitor instead of waiting for its next scheduled run, and returns any detected changes.No findings

    Why it is in this group

    • The description's first verb is "trigger": a word for a change.
    Description, as the server wrote it
    Triggers an immediate check for a monitor instead of waiting for its next scheduled run, and returns any detected changes.
  • create_semantic_monitorWatches a URL on a schedule and reports what changed and whether it matters, explained by AI — not just a pixel-diff percentage.No findings

    Why it is in this group

    • The name "create_semantic_monitor" says "create": a word for a change.
    Description, as the server wrote it
    Watches a URL on a schedule and reports what changed and whether it matters, explained by AI — not just a pixel-diff percentage. Use this for competitor pricing pages, changelogs, status pages, or any page whose changes should trigger a workflow.
Only reads 3Claude Code: allow
  • find_elementsReturns only the interactive elements of a page (buttons, links, inputs) with role, label, CSS selector and pixel coordinates.No findings

    Why it is in this group

    • The name "find_elements" says "find": a word for reading.
    Description, as the server wrote it
    Returns only the interactive elements of a page (buttons, links, inputs) with role, label, CSS selector and pixel coordinates. Use this before acting on a page (computer-use / Set-of-Marks style grounding) instead of capture_context when you only need to know what can be clicked and where.
  • get_monitor_changesReturns the recent check history for a monitor, including detected changes with their relevance and explanation.No findings

    Why it is in this group

    • The name "get_monitor_changes" says "get": a word for reading.
    Description, as the server wrote it
    Returns the recent check history for a monitor, including detected changes with their relevance and explanation.
  • list_monitorsLists your active monitors and their IDs, URLs and schedules.No findings

    Why it is in this group

    • The name "list_monitors" says "list": a word for reading.
    Description, as the server wrote it
    Lists your active monitors and their IDs, URLs and schedules.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
