• publish_website

  Yeetit - POST HTML, get a URL. No account needed.

  Publish HTML content to a live URL instantly. No account or API key required. Returns a public URL that anyone can visit. Sites expire after 24 hours unless the owner claims them. Use this when a user asks you to build, create, or deploy a website, landing page, invitation, portfolio, report, or any HTML content they want to share as a link. Supports bundled assets (CSS, JS, images) and multi-page sites (include additional .html files in assets, accessible at /{slug}/{pagename}). IMPORTANT: After publishing, always share the live URL and the claim URL with the user. The claim URL lets them take permanent ownership of the site. Store the edit_key from the response silently — do not show it to the user — you will need it if they ask you to make changes to the site later. If you lose the edit_key, ask the user to claim the site first (via the claim URL in the page footer), then provide you with their API key from the dashboard — you can use that instead.

• get_starter

  pdfzen

  Fetch the full HTML body, CSS, sampleData, and pageOptions for one starter template by slug. Use this when you need to understand the exact shape of `data` the template expects before calling render_template_to_pdf, or when you want to fork a starter into custom HTML. Free, no payment, no auth required.

• 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.

• validate_html

  Dock

  Pre-flight check on html / css / js BEFORE writing via update_html. Returns { ok, errors, warnings, parsed } where parsed has byte counts per field and `dropped` (true if the sanitizer would strip anything from `html`). Errors cover cap breaches (`html_too_large`, `css_too_large`, `js_too_large`, `total_too_large`) and sanitizer rejection (`html_sanitize_rejected`, `html_sanitize_empty`). At v2 the sanitizer accepts `<script>` and `<link>` — those used to be smells but are now first-class agent markup; isolation lives in the opaque render iframe, not the sanitizer. The smells still stripped: inline `on*=` attributes, `javascript:`/`data:text/html` URIs, `<meta http-equiv>` tags. NEVER writes anything. Use when iterating on a payload so you don't burn a write on something the surface would reject.

• fetch_url

  SteadyFetch

  Fetch a URL with full reliability — retry, circuit breaker, cache, and anti-bot bypass. Returns both raw HTML and clean markdown. Automatically retries on failure with exponential backoff, falls back to plain HTTP if browser fetch fails, and circuit-breaks domains that are consistently down. Args: url: The URL to fetch use_cache: Whether to use cached results (default: true, TTL 1 hour) js_render: Whether to render JavaScript (default: true, disable for speed) wait_for: CSS selector to wait for before capturing (e.g., '.results-loaded')

• switch_dannet_server

  dannet

  Switch between local and remote DanNet servers on the fly. This tool allows you to change the DanNet server endpoint during runtime without restarting the MCP server. Useful for switching between development (local) and production (remote) servers. Args: server: Server to switch to. Options: - "local": Use localhost:3456 (development server) - "remote": Use wordnet.dk (production server) - Custom URL: Any valid URL starting with http:// or https:// Returns: Dict with status information: - status: "success" or "error" - message: Description of the operation - previous_url: The URL that was previously active - current_url: The URL that is now active Example: # Switch to local development server result = switch_dannet_server("local") # Switch to production server result = switch_dannet_server("remote") # Switch to custom server result = switch_dannet_server("https://my-custom-dannet.example.com")

• get_html

  Dock

  Read an HTML surface's body. HTML surfaces (Surface.kind="html") store mockup or full-page content as three text fields (html, css, js) rendered together inside a sandboxed iframe. Use `list_surfaces` to enumerate html surfaces in a workspace. Omit `surface_slug` to read the primary html surface; pass it to target a specific tab. Empty (never-written) html surfaces return { html:"", css:"", js:"" }. 404 when `surface_slug` doesn't match a live html surface. Requires viewer role.

  Connector

• create_surface

  Dock

  Create a new surface (tab) inside a workspace. `kind` picks `table`, `doc`, or `html`. Optional `slug` (lowercase kebab-case, 3-64 chars); when omitted the server slugifies `name` and appends a numeric suffix on collision. Optional `columns` overrides the default Title/Status/Notes triple for `table` kinds; ignored for `doc` and `html`. `html` surfaces start with an empty body — write content via `update_html`. Editor role required. Emits `surface.created` so live listeners on the workspace stream see the new tab without a refetch.

  Connector

• read_display_html

  agentView

  Reads the raw HTML source code currently shown on a display. Use this to inspect, modify or reuse existing content. Typical workflow: read_display_html to get the HTML, make changes, then send_html to push it back. Returns the complete HTML string plus metadata. If no live content is active, returns idle content if set. Requires content_only scope.

  Connector

• report_get

  Kash.click

  Download a synthetic HTML sales report for a given period. Period logic: omit all date fields to get yesterday's report; provide y only for a full-year report; y + m for a full-month report; y + m + d for a specific day. Returns an HTML summary including total revenue, number of orders, breakdown by department, VAT summary, and payment methods.

  Connector

• send_html

  agentView

  Pushes raw HTML to one display, replacing current content. Prefer send_url only when the user explicitly wants an external web page. Include a human-readable description so get_display_content can summarize intent without reading raw HTML. Before complex content, call get_display_capabilities to match the real browser/runtime. When no design system is supplied, use premium digital-signage quality: full-screen layout, strong hierarchy, refined typography, robust fallback data, and no action buttons unless touch is requested. Exactly one of html or base64_html is required. Requires content_only scope and display management access. Returns id, name, duration, file and version.

• intel_stack

  TunnelMind Data API

  Fetches up to 32KB of the domain's HTML and response headers from the edge, then fingerprints the content for known CMS platforms, JavaScript frameworks, CDN providers, and analytics tools. Detection is based on meta generator tags, script src patterns, response headers, and cookie names. Use this tool when: - You need to know what CMS (WordPress, Drupal, Shopify) a site runs. - You are assessing a domain's infrastructure before a security review. - You want to identify analytics or marketing tools a site embeds. Do NOT use this tool when: - You want HTTP headers and security posture — use `intel_http` instead. - You want tracker database classification — use `get_domain` instead. - You need robots.txt AI policy — use `intel_robots` instead. Inputs: - `domain` (query, required): Domain to fingerprint. Returns: - `cms`: detected content management system, or null. - `frameworks`: JavaScript/backend frameworks detected. - `cdn`: CDN provider detected, or null. - `analytics`: analytics and tracking tools detected. - `meta_generators`: raw meta generator tag values. Cost: - Free. No API key required. Latency: - Typical: 2-4s (HTML fetch), p99: 7s.

• 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"])

• get_install_instructions

  petal-components-mcp

  Get the canonical steps for installing petal_components in a Phoenix project. Call this when the user asks to install petal_components, when you are setting up a new Phoenix project that needs UI components, or when verifying an existing installation. Returns step-by-step instructions covering mix.exs, mix deps.get, Tailwind v4 CSS config, and the web module import. Steps are idempotent - safe to follow on a project that is partially configured.

  Connector

• test_display_content

  agentView

  DRY-RUN validator for HTML payloads. Pushes the HTML through agentView's size + description checks WITHOUT touching any real display. Use this when an LLM has just generated HTML and you want to confirm it is well-formed and within limits BEFORE risking a real send_html call (e.g. after composing a complex layout, or before broadcasting to many displays). No display_id is needed; the response carries simulated=true and a safe size summary. Capped at 1 MB. Authenticated, but no display-scope check — only verb-level enforcement.

• fetch_ddo_definition

  dannet

  Fetch the full, untruncated definition from DDO (Den Danske Ordbog) for a synset. This tool addresses the issue that DanNet synset definitions (:skos/definition) may be capped at a certain length. It retrieves the complete definition from the authoritative DDO source by following sense source URLs. WORKFLOW: 1. Get synset information to find associated senses 2. Extract DDO source URLs from sense data (dns:source) 3. Fetch DDO HTML pages and parse for definitions 4. Find elements with class "definitionBox selected" and extract span.definition content IMPORTANT NOTES: - Looks for CSS classes "definitionBox selected" and child span.definition - DDO and DanNet have diverged over time, so source URLs may not always work - This implementation uses httpx for web requests and regex-based HTML parsing Args: synset_id: Synset identifier (e.g., "synset-1876" or just "1876") Returns: Dict containing: - synset_id: The queried synset ID - ddo_definitions: List of definitions found from DDO pages - source_urls: List of DDO URLs that were attempted - success_urls: List of URLs that successfully returned definitions - errors: List of any errors encountered - truncated_definition: The original DanNet definition for comparison Example: result = fetch_ddo_definition("synset-3047") # Check result['ddo_definitions'] for full DDO definitions # Compare with result['truncated_definition'] from DanNet
