    SummaryIntent-aware visual verification for coding agents: the agent declares what a UI change should affect, and SnapDiff diffs the page against a baseline and flags anything that changed outside that intent for review or rollback — local screenshot capture via Playwright.MCP server for screenshots, PDFs, OG images, and narrated video recording from Claude Desktop, Cursor, and Windsurf.

    Tools & Capabilities Breakdown

    Snapdiff Mcp Tools (4)

    snapdiff_verify_ui_change
    Checks whether a visual change matches the agent's stated intent. Returns `verdict` (`pass` / `expected_change_detected` / `unexpected_regression` / `no_change_detected` / `needs_human_review`) and a `next_action`. Requires a project + baseline. **Use this in the verification loop.
    snapdiff_compare_pages
    Raw visual diff between two URLs, or a URL vs. a stored project baseline. Use for ad-hoc diffs that don't fit the verify-ui-change verdict shape.
    snapdiff_capture_screenshot
    Single screenshot of a URL.
    snapdiff_html_to_image
    Render HTML/CSS to an image (OG cards, social images, email headers).

    Pagebolt Mcp Tools (17)

    take_screenshot
    Capture a screenshot of a URL, HTML, or Markdown content. Supports device emulation, ad/chat/tracker blocking, metadata extraction, geolocation, timezone, styling (macOS/Windows frames, gradient/glass backgrounds, shadows), and more. Returns an image (PNG, JPEG, or WebP).
    generate_pdf
    Generate a PDF from a URL or HTML content. Supports custom margins, headers/footers, page ranges, and scaling. Saves the PDF to disk and returns the file path.
    create_og_image
    Generate an Open Graph / social card image. Returns an image using built-in templates or custom HTML.
    run_sequence
    Execute a multi-step browser automation sequence. Navigate pages, interact with elements (click, fill, select), and capture multiple screenshots/PDFs/diffs in a single browser session. Use the "diff" step to compare the current page state against another URL after automation. Each output counts as 1 API request.
    record_video
    Record a professional demo video of a multi-step browser automation sequence. Produces MP4/WebM/GIF with cursor highlighting, click effects, smooth movement, step notes, browser frame (macOS/Windows), gradient/glass backgrounds, and more. Costs 3 API requests. Saves to disk. BEST PRACTICE: Keep videos concise (5-15 action steps). Do NOT add wait steps between every action — the pace parameter handles timing. Only use wait for page loads or narration holds. Do NOT use zoom unless the user explicitly asks for it.
    inspect_page
    Inspect a web page and get a structured map of all interactive elements, headings, forms, links, and images — each with a unique CSS selector. Use this BEFORE run_sequence or record_video to discover what elements exist on the page and get reliable selectors. Returns text (not an image), so it is fast and cheap. Costs 1 API request.
    observe_page
    Get a compact, token-budgeted "observation" of any web page, purpose-built for AI agents. In ONE request it returns: id-indexed interactive elements (role, name, CSS selector, state), a heuristic page-type classification (login, signup, search, article, form, generic), and grouped "suggested actions" (login flow, search, primary buttons, navigation). Optionally include readable content (Markdown), the ARIA tree, and a screenshot. This is the fastest way for an agent to understand and act on an un-instrumented page — far more token-efficient than a raw screenshot or full DOM. Use the returned selectors with run_sequence to act. Costs 1 API request.
    import_agent_trace
    Convert a page-agent/browser-use action trace into a re-runnable PageBolt sequence. Give it the array of actions a page-agent produced (each entry may be either {action, index|selector, value, ...} or the {action_name: {...}} shape) plus, optionally, the selectors map from observe_page with format:"flatdomtree" to resolve indices to CSS selectors. Set save:false for a dry run that returns the translated steps without persisting. This endpoint does NOT consume request quota. Pair with observe_page (format:"flatdomtree") → run an agent → import_agent_trace to turn an ad-hoc agent run into a deterministic, replayable sequence.
    act_on_page
    Give PageBolt a URL and a plain-English GOAL; it runs an observe→plan→act→verify loop server-side until the goal is met, then returns a structured trace of every action it took plus a success/failure status. This is the "hands" on top of observe_page (the "eyes") — you do NOT author selectors or a step list yourself. Use act_on_page when you only know the OUTCOME you want (e.g. "log in and open billing", "accept the cookie banner and start a trial"); use run_sequence when you already know the exact deterministic steps/selectors (cheaper). Available on Starter+ plans. Cost is metered: 2 requests base + 1 per step taken. SECURITY: page text is treated as untrusted — the agent pursues only your goal and ignores instructions embedded in the page. Scope allowedDomains tightly and avoid destructive flows.
    visual_diff
    Compare two web pages (or HTML strings) pixel-by-pixel and return a diff image highlighting all visual differences. Supports full-page capture, device emulation, element selectors, and all screenshot-like options. Returns the diff image, changed pixel count, and percentage changed. Costs 1 API request.
    list_devices
    List all available device presets for viewport emulation (e.g. iphone_14_pro, macbook_pro_14). Use the returned device names with the viewportDevice parameter in take_screenshot.
    check_usage
    Check your current PageBolt API usage and plan limits.
