npm version npm downloads License: MIT MCP Badge

MCP server for Rendex — render raw HTML, Markdown, or any URL to an image or PDF via AI agents using the Model Context Protocol.

Quick Start

Claude Desktop / Cursor / Windsurf (npx)

Add to your MCP client config:

{
  "mcpServers": {
    "rendex": {
      "command": "npx",
      "args": ["-y", "@copperline/rendex-mcp"],
      "env": {
        "RENDEX_API_KEY": "your-api-key"
      }
    }
  }
}

Where to add this:

Client	Config location
Claude Desktop	`~/Library/Application Support/Claude/claude_desktop_config.json` (macOS)
Cursor	`.cursor/mcp.json` in project root, or Settings > MCP
Windsurf	Settings > MCP Servers

Claude Code (CLI)

Add a .mcp.json to your project root with the same config above. Then restart Claude Code.

Important: Add .mcp.json to your .gitignore — it contains your API key.

Remote (zero-install, OAuth or API key)

Connect to the hosted server at https://mcp.rendex.dev/mcp — no install needed. It's fronted by OAuth 2.1 (authorization-code + PKCE S256), so OAuth-capable clients (ChatGPT, Claude, Cursor, the MCP Inspector) connect with no API key — you sign in with a one-time email code and each caller bills against their own Rendex plan and credit pool.

Clients that prefer a static key can still pass one directly:

{
  "mcpServers": {
    "rendex": {
      "url": "https://mcp.rendex.dev/mcp",
      "headers": {
        "Authorization": "Bearer your-api-key"
      }
    }
  }
}

`rendex_extract`

Extract 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 — handling 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.

"Extract the article text from https://example.com/post as Markdown"
"Pull the readable content from this SPA as JSON so I can summarize it"

Parameters:

Parameter	Type	Default	Description
`url`	string	required	Webpage URL to extract readable content from
`extractFormat`	`"markdown"` \| `"json"` \| `"html"`	`"markdown"`	Output shape — `markdown` (LLM-friendly prose), `json` (structured: title/byline/excerpt/siteName/length), or `html` (cleaned reader-mode HTML)
`device`	string	—	Device preset (`desktop`, `iphone_15`, `iphone_se`, `pixel_8`, `ipad`, `ipad_pro`) — extract the mobile/tablet version of a page
`blockAds`	boolean	`true`	Block ads and trackers before extraction
`blockCookieBanners`	boolean	—	Hide common cookie/consent walls before extraction
`hideSelectors`	string[]	—	CSS selectors to hide before extraction, e.g. `['.modal', '#newsletter-popup']`. Max 50
`waitUntil`	string	`"networkidle2"`	Page readiness: `load`, `domcontentloaded`, `networkidle0`, `networkidle2`
`timeout`	number	`30`	Max seconds to wait for page load (5-60)

`rendex_render_link`

Render a URL, raw HTML, or Markdown and get 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 parameters as rendex_screenshot, plus an optional expiresIn. Returns { url, expiresAt, format, cacheTtl }.

"Make me a hosted OG-image URL for this Markdown release note"
"Give me a render link for this HTML card that I can drop into og:image"

Parameter	Type	Default	Description
(all `rendex_screenshot` params)	—	—	Same source (`url`/`html`/`markdown`), format, sizing, and templating options
`expiresIn`	number	server TTL	Seconds until the signed URL expires (60–2592000)

`render_artifact`

Turn Markdown or HTML into a branded, downloadable artifact — a PDF, a PNG, and a hosted share page — in one call. Ideal for agent outputs: reports, invoices, summaries, release notes, dashboards. Apply a logo, accent color, font, header, and footer; choose PDF page size/orientation/margins. Returns hosted URLs { pdfUrl, pngUrl, shareUrl, expiresAt } — no storage needed on your side. Each requested format costs 1 render credit.

"Turn this Markdown report into a branded PDF and PNG with our logo and an orange accent"
"Render this invoice HTML to a PDF and give me a share link that expires in a week"

Parameter	Type	Default	Description
`content`	string	required	The Markdown or HTML body to render (up to ~4MB)
`inputFormat`	`"markdown"` \| `"html"`	`"markdown"`	How to interpret `content` — `markdown` is converted to styled HTML; `html` is used as a body fragment
`formats`	`("pdf" \| "png")[]`	`["pdf","png"]`	Which formats to produce. Each costs 1 credit
`accentColor`	string	—	CSS accent color for the bar, links, and headings (e.g. `#EA580C`)
`logo`	string	—	http(s) URL of a logo image shown in the header
`header`	string	—	plain-text header line shown beside the logo
`footer`	string	—	plain-text footer line shown at the bottom
`font`	string	—	CSS font-family stack for the body
`pageSetup`	object	—	`{ size, orientation, margin{top,right,bottom,left}, scale, width, height, fullPage }`
`data`	object	—	Mustache data — when set, `content` is rendered as a logic-less Mustache template (plus `{{logo}}`/`{{header}}`/… from `branding`) before conversion
`expiresIn`	number	`86400`	Seconds until the hosted URLs expire (3600–2592000). Default 24h

Rendex Watch

Monitor a URL on a schedule and get notified when it changes — real-Chrome visual diff (with a highlighted overlay), an extracted-text diff, or both. Eight tools let an agent set up, inspect, edit, and tear down watches on the shared Rendex platform (one rdx_ key, one credit pool).

"Watch https://example.com/pricing for visual changes and alert my webhook"
"Before I save it, test whether you can capture #pricing on that page"
"Show me the last few runs of watch <id> — did anything change?"

Tool	Purpose	Key inputs
`watch_create`	Create a watch (active → captures its baseline now)	`url`, `name?`, `intervalMinutes?`, `diffMode?` (visual/text/both), `threshold?`, `renderParams?`, `webhookUrl?` (Starter+), `notifyEmail?`, `paused?`
`watch_test`	Dry-run a config first (creates nothing)	same as `watch_create`
`watch_list`	List your watches	`status?` (active/paused/all), `cursor?`, `limit?`
`watch_get`	Fetch one watch (+ baseline URL)	`id`
`watch_run`	Run a check now (1 credit)	`id`
`watch_runs`	Run history with signed before/after/overlay URLs	`id`, `cursor?`, `limit?`
`watch_update`	Edit a watch in place — interval, diff mode, channels, render params	`id`, plus any `watch_create` field; `webhookUrl`/`notifyEmail` accept `null` to clear a channel
`watch_delete`	Delete a watch + its runs	`id`

renderParams carries the per-check capture knobs (fullPage defaults to true, selector, device, geo (Pro+), plus noise controls ignoreRegions/ignoreText/minTextChars/suppressWhilePresent and uaMode). Interval floors are per-plan (Free 1440 / Starter 180 / Pro 30 / Enterprise 5). Watch metadata + signed image URLs are returned as JSON text.

`rendex_account`

Check the account from inside the agent: which plan it's on, how many render credits have been used this month vs. the limit (and when it resets), the per-minute rate limit, and a one-tap upgrade link. Lets an agent answer "how much have I used?" or "how do I get more renders?" without sending the user to the dashboard. Read-only — costs no credits.

"How many Rendex renders do I have left this month?"
"What plan am I on, and how do I upgrade for more?"

Returns { plan, usage: { used, limit, remaining, unlimited, resetsAt }, rateLimitPerMinute, upgrade: { recommendedPlan, recommendedPlanCredits, upgradeUrl, manageBillingUrl } }.

Data templating

Turn one reusable template into many documents. Pass a data object alongside html or markdown, and Rendex renders the string as a logic-less Mustache template before capture — {{var}} interpolation, {{#items}}…{{/items}} loops, and nested {{a.b}} access. Great for invoices, reports, certificates, and OG cards.

"Render this HTML invoice template to a PDF, filling it with this data:
 <h1>Invoice {{number}}</h1><p>Total: {{total}}</p>
 data = { number: 'INV-014', total: '$2,400' }"

data is valid only with html or markdown — combining it with url returns a validation error.

Authentication

Get your API key at rendex.dev.

Set the RENDEX_API_KEY environment variable in your MCP client configuration.
