What this server can do
13 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
render_artifact(data, font, logo, footer, header, content, formats, expiresIn, pageSetup, accentColor, inputFormat)- Use this when the user asks to make or create a branded report, invoice, summary, release notes, or document — or to 'turn this Markdown/HTML into a PDF and PNG' (optionally with a logo or accent color). Do NOT use to screenshot an existing URL (use rendex_screenshot). Turns Markdown or HTML into a branded, downloadable artifact — a PDF, a PNG, and a hosted share page — in one call. Apply a logo, accentColor, font, header, and footer. Returns hosted URLs { pdfUrl, pngUrl, shareUrl, expiresAt }. Each requested format costs 1 render credit. Required: content.
rendex_account- Check the Rendex account: which plan it's on, how many render credits have been used vs. the monthly limit (and when it resets), the per-minute rate limit, and a one-tap link to upgrade to a higher tier. Use this whenever the user asks about their usage, remaining quota, current plan, or how to get more renders / stop hitting limits. Read-only — costs no credits.
rendex_extract(url, device, timeout, blockAds, waitUntil, extractFormat, hideSelectors, blockCookieBanners)- Use this when the user asks to read, extract, get the text/content/article of, or summarize a webpage/URL. Do NOT use for a visual screenshot (use rendex_screenshot). Extracts clean reader-mode content from any webpage as Markdown, JSON, or HTML. Runs the same Chromium render pass as a screenshot, so it captures content after JavaScript runs — handles SPAs that fetch-only readers miss. Strips nav, ads, and boilerplate, returning the article body plus title, byline, and excerpt. Great for feeding page content to an LLM, summarization, or RAG ingestion. Costs 1 render credit per call. Required: url.
rendex_render_link(js, css, geo, url, data, html, delay, width, device, format, height, cookies, geoCity, headers, quality, timeout, blockAds, darkMode, fullPage, geoState, markdown, pdfScale, selector, expiresIn, pdfFormat, pdfMargin, userAgent, waitUntil, bestAttempt, resizeWidth, pdfLandscape, resizeHeight, hideSelectors, waitForSelector, deviceScaleFactor, blockCookieBanners, blockResourceTypes, pdfPrintBackground)- Use this when the user wants a reusable, HOSTED image URL — an og:image or a link to embed in an <img> tag — rather than the image bytes. Do NOT use for a one-off inline screenshot (use rendex_screenshot). Renders a URL, raw HTML, or Markdown and gives back a signed, hosted, edge-cached image URL instead of the bytes — ideal for dynamic OG images: drop the URL into <meta property="og:image"> or an <img> tag and Rendex serves a cached copy on every share. Takes the same options as rendex_screenshot, plus an optional expiresIn. Returns { url, expiresAt, format, cacheTtl } as JSON. Costs 1 render credit per fresh render; cached repeat hits don't re-charge.
rendex_screenshot(js, css, geo, url, data, html, delay, width, device, format, height, cookies, geoCity, headers, quality, timeout, blockAds, darkMode, fullPage, geoState, markdown, pdfScale, selector, pdfFormat, pdfMargin, userAgent, waitUntil, bestAttempt, resizeWidth, pdfLandscape, resizeHeight, hideSelectors, waitForSelector, deviceScaleFactor, blockCookieBanners, blockResourceTypes, pdfPrintBackground)- Use this when the user asks to screenshot, capture, or take a picture of a webpage/URL, or to render raw HTML or Markdown to an image or PDF. Do NOT use to get a reusable hosted image URL (use rendex_render_link) or to make a branded multi-format document (use render_artifact). Captures a screenshot or PDF of any webpage, raw HTML, or Markdown. Supports full-page capture, dark mode, ad blocking, custom viewports, CSS/JS injection, cookie/header injection, PDF output, HTML and Markdown rendering, and progressive fallback for heavy sites. Returns partial renders on timeout by default (bestAttempt mode). Costs 1 render credit per call. Cookie/header injection requires Starter+; geo-targeting requires Pro+.
watch_create(url, name, paused, diffMode, aiSummary, threshold, webhookUrl, notifyEmail, renderParams, intervalMinutes)- Use this when the user asks to monitor, watch, or track a webpage for changes, or to be alerted/notified when a page changes. Do NOT use for a one-time capture (use rendex_screenshot). Creates a Rendex Watch — monitors a URL on a schedule and notifies when it changes (real-Chrome visual diff with a highlighted overlay, an extracted-text diff, or both). An active watch captures its baseline immediately. Returns the created watch as JSON. Required: url.
watch_delete(id)- Delete a watch and its run history. Irreversible. Required: id.
watch_get(id)- Fetch one watch by ID, including its current baseline image URL and status. Returns JSON. Required: id.
watch_list(limit, cursor, status)- List your watches (newest first), optionally filtered by status and paged. Returns { items, nextCursor }.
watch_run(id)- Run an immediate check now (charges 1 credit). Returns the queued run; poll watch_runs for the result or receive a watch.changed webhook. Required: id.
watch_runs(id, limit, cursor)- Read a watch's run history (newest first), paged. Each run includes changed, diffScore, and signed before/after/overlay image URLs. Returns { items, nextCursor }. Required: id.
watch_test(url, name, paused, diffMode, aiSummary, threshold, webhookUrl, notifyEmail, renderParams, intervalMinutes)- Dry-run a watch config BEFORE creating it — render the proposed config once and report what was captured + whether the page is reachable (and the text a text-watch would compare). Creates no watch, no baseline, no diff. Use this to validate a selector/scope/identity first. Returns JSON. Required: url.
watch_update(id, url, name, paused, diffMode, aiSummary, threshold, webhookUrl, notifyEmail, renderParams, intervalMinutes)- Update a watch in place — pause/resume (paused), re-point (url), change schedule/diff/notify settings, or turn a channel off (webhookUrl/notifyEmail = null). Only the fields you send change; renderParams is deep-merged over the existing config. A scope change (url/selector/fullPage/size/device) re-baselines on the next check. Returns the updated watch as JSON. Required: id.

Signals
These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
| Signal | Value | What it measures | Window | Observed | Source |
|---|---|---|---|---|---|
| GitHub stars | 7 | Number of GitHub accounts that bookmarked this repository since it was created. It is a bookmark count, not installs, not active users and not quality. | cumulative, all time | GitHub | |
| Last commit | 2026-08-04 | Date of the most recent push to any branch. This is the strongest cheap indicator of whether the project is still maintained. | point in time | GitHub | |
| Open issues | 1 | Open issues plus open pull requests, as GitHub counts them together. A high number can mean an active project or an abandoned one. | as of fetch | GitHub | |
| Latest published version | 1.8.2 | Latest version string the maintainer published to the registry. | as of fetch | Model Context Protocol | |
| Registry record last updated | 2026-07-20 | When the registry record was last updated by its maintainer. | point in time | Model Context Protocol | |
| License | MIT | Licence GitHub detected in the repository. Detection can be wrong; the LICENSE file is authoritative. | as of fetch | GitHub | |
| First listed in the MCP Registry | 2026-07-20 | Date this server was first published to the official MCP Registry. Not a usage or quality measure. | point in time | Model Context Protocol | |
| repository status | active | The repository exists on GitHub and is not archived. This says nothing about how recently it was worked on. | as of fetch | GitHub | |
| mcp tools declared | 13 tools | Number of functions the server itself declared when asked to list them. This is what the server offers an agent, not a measure of how well any of them work. | as of probe | mcp.rendex.dev | |
| mcp endpoint status | ok | The server listed 13 functions when asked. | as of probe | mcp.rendex.dev |
