"How to execute tests on a frontend page and debug browser console issues" matching MCP tools:

• web_url_reader

  Inferventis MCP Server

  Fetches any public web page and returns clean, readable plain text stripped of HTML, navigation, scripts, advertisements, and boilerplate. Returns the page title, meta description, word count, and main body text ready for analysis or summarisation. Use this tool when an agent needs to read the content of a specific web page or article URL — for example to summarise an article, extract facts from a page, verify a claim by reading the source, or convert a web page into plain text to pass to another tool. Pass article URLs returned by web_news_headlines to this tool to read full article content. Do not use this tool to discover current news headlines — use web_news_headlines instead. Does not execute JavaScript — best suited for standard HTML content pages. Will not work with paywalled, login-protected, or JavaScript-rendered single-page applications.

• getPagePostInsights

  NotFair-MetaAds

  Aggregate engagement metrics for a Page post (typically the post backing a boosted-post ad). Returns impressions, reach, reactions, and aggregate like / comment / share counts — never individual user data. Pair with `getInsights` to compare paid + organic performance on a boosted post.

  Connector

• end_session

  sncro

  Explicitly close a sncro session — "Finished With Engines". Call this when you are done debugging and will not need the sncro tools again in this conversation. After this returns, all sncro tool calls on this key will refuse with a SESSION_CLOSED message — that is your signal to stop trying to use them and not apologise about it. Use it when: - The original problem is solved and the conversation has moved on - The user explicitly says "we're done with sncro for now" - You're entering a long stretch of work that won't need browser visibility The session can't be reopened. If you need browser visibility later, ask the user whether to start a new one with create_session.

• check_pricing

  Ground Truth

  Fetch a public pricing page and extract first-pass pricing signals before you quote plan costs, free tiers, or plan names. Use this when you already have a likely pricing URL and need a quick live scan of visible page text. It returns price-like strings, heuristic plan labels, free or free-trial signals, and cache information. It does not map prices to exact plans, normalize currencies, execute checkout flows, or guarantee that a price applies to a specific region or customer type. JavaScript-rendered, logged-in, or heavily obfuscated pricing details can be missed. Results are cached for 5 minutes.

• test_hypothesis

  Ground Truth

  Run a small verification plan made of concrete live checks and summarize whether a hypothesis is supported. Use this when one conclusion depends on multiple simple checks such as endpoint reachability, npm search counts, or whether a page contains an exact substring. This is a coordination tool, not an open-ended research agent: every test must be explicitly defined in advance, and tests run in order with no branching or early exit. The final verdict is mechanical: all tests passing => SUPPORTED, zero passing => REFUTED, otherwise PARTIALLY SUPPORTED. Use verify_claim when you already have evidence URLs, estimate_market for category sizing, and compare_competitors when you already know exact package names.

• create_edit_session

  mcp

  Creates a visual edit session so the user can upload and manage images on their published page using a browser-based editor. Returns an edit URL to share with the user. When creating pages with images, use data-wpe-slot placeholder images instead of base64 — then create an edit session so the user can upload real images.

• get_about

  Follow On Tours

  Get information about Follow On Tours — who we are, how we work, our experience, and how the bespoke cricket travel service operates. Use this when someone asks who Follow On Tours is or how the service works.

  Connector

• audit

  mcp

  Perform comprehensive audit of a website URL. Fetches the URL content ONCE and provides a combined report with: - Classification: category, subcategory, language, sentiment, demographics - SEO Analysis: score, grade, issues, recommendations - EEAT Analysis: experience, expertise, authoritativeness, trustworthiness scores - AEO Analysis: AI answer engine optimization score, metrics, issues, signals (includes full Citation Readiness analysis in the nested 'citation' key) - Advertiser Matching: best-fit advertising networks with scores - Similar Sites: competitor/related sites from the same category This is more efficient than calling classify_url, analyze_seo, analyze_eeat, analyze_aeo, select_advertiser, and find_similar_sites separately as it only fetches the page once. Args: url: The website URL to audit (e.g., "https://example.com"). Returns: Comprehensive audit report with: - url: The analyzed URL - classification: Category, subcategory, language, sentiment, demographics - seo: Score, grade, issues, recommendations - eeat: EEAT score, grade, category scores, issues, signals - aeo: AEO score, grade, metrics, issues, signals (includes citation results) - advertisers: Matched advertising networks with scores - similar_sites: Related sites from the same category (up to 10) - cached: Whether result was from cache

• run_code

  Hatchable

  Execute arbitrary JS in the project's isolate runtime. The SDK is pre-imported into local scope — `db`, `auth`, `email`, `storage`, `ai`, `agent`, `cache`, `vector`, `memory`, `tasks`, `scheduler`, `browser`, `images`, `run`, `approval`, `mcp` are ready to use without import. `process.env` and global `fetch` also work. `return` to produce the `result` field. Top-level `import` and dynamic `import('hatchable')` are NOT supported in this REPL — the bindings above are how you reach the SDK. Use this as a REPL: probe the database, verify a computation, test an API shape before committing it to a file. Nothing is persisted — the snippet runs once and disappears. Caps: 5s default timeout (max 30s), 256 KB max source length. Example: run_code({ project_id, code: ` const { rows } = await db.query("SELECT count(*) FROM users"); return rows[0]; `})

• pageviews_count

  convalytics

  Count page views for a specific project in a time window. Page views are the automatic hits captured by the browser script tag (separate from custom events). Use this for web-traffic questions like 'how many pageviews in the last 24 hours'. Default window is the last 7 days. Pass `user` to scope to one visitor.

• web_url_reader

  Inferventis — Financial Data, News & Web MCP

  Fetches any public web page and returns clean, readable plain text stripped of HTML, navigation, scripts, advertisements, and boilerplate. Returns the page title, meta description, word count, and main body text ready for analysis or summarisation. Use this tool when an agent needs to read the content of a specific web page or article URL — for example to summarise an article, extract facts from a page, verify a claim by reading the source, or convert a web page into plain text to pass to another tool. Pass article URLs returned by web_news_headlines to this tool to read full article content. Do not use this tool to discover current news headlines — use web_news_headlines instead. Does not execute JavaScript — best suited for standard HTML content pages. Will not work with paywalled, login-protected, or JavaScript-rendered single-page applications.

  Connector

• create_funnel

  convalytics

  Create a new funnel on a project. Steps are 2–10 ordered events or pageview paths. conversionWindowMs caps how long a visitor has between consecutive steps (default 7 days); this is the step-to-step limit, without which a funnel is just event co-occurrence. Returns { id } on success.

  Connector

• setup_account

  Hatchable

  Associate an email and handle with your account. Step 1: Call with just email — sends a 6-digit verification code. Step 2: Call with email + code + handle — verifies and completes setup. This lets you log in to the console and sets your permanent @handle.

  Connector

• query_element

  sncro

  Query a DOM element by CSS selector. Returns bounding rect, attributes, computed styles, inner text, and child count. Use this to debug layout, positioning, and visibility issues. Requires a connected browser session. If you get BROWSER_NOT_CONNECTED, call check_session first and wait for "connected" status. If you get BROWSER_TIMEOUT, the page may be navigating — wait a moment and retry. Args: key: The sncro session key secret: The session secret from create_session selector: CSS selector (e.g. "#photo-wrap", ".toolbar > button:first-child") styles: Optional list of CSS properties to read (e.g. ["transform", "width", "display"])

  Connector

• set_confirmation_mode

  AI Agents Overflow

  Toggle confirmation mode for write operations. When ON (default): submit_problem, submit_solution, and upvote_answer return a preview for user approval before executing. You must then call confirm_action(action_id) or cancel_action(action_id). When OFF: write operations execute immediately as before. The user can ask you to turn this on or off at any time.

• ask_kamy

  Kamy

  Ask Kamy Brain a question about Kamy itself — how to use it, why something failed, which plan to pick, what fields a template needs. Returns a paragraph answer drawing on the full Kamy documentation. For rendering a PDF, use render_pdf instead.

• mimiq.test_flow

  Mimiq - Synthetic User Testing

  Deep interactive simulation of a multi-step user flow (signup, onboarding, checkout, multi-page funnel). Each simulated persona navigates the page interactively — clicking links, filling forms, reading content, making decisions at each step. Use this for complex flows where you need to find exactly WHERE users get stuck or abandon. Slower than test_page (uses real browser sessions) but reveals step-by-step journey issues. Returns: raw per-persona journey data with step-by-step actions and drop-off points.

  Connector

• get_network_log

  sncro

  Get network performance data from the browser. Returns resource timing entries (URLs, durations, sizes) sorted by duration (slowest first), plus page navigation timing. Use this to find slow API calls, large assets, or overall page load performance. Requires a connected browser session. If you get BROWSER_NOT_CONNECTED, call check_session first and wait for "connected" status. Args: key: The sncro session key secret: The session secret from create_session limit: Max resources to return (default 50) type: Filter by initiator type (e.g. "fetch", "xmlhttprequest", "img", "script", "css")
