Render tools (6, 1 write)

write = sends, deletes, buys or posts
  • accessibility_auditwrite actionFree

    Run a WCAG accessibility audit on a page using axe-core in a real browser, and report the violations with the elements responsible. Because it runs against a genuinely rendered page, colour-contrast and other rules that depend on layout and computed colour actually fire — these are silently skipped by audits that parse HTML without a layout engine. Use this to check a page meets WCAG before shipping.

  • inspect_elementFree

    Answer 'why isn't this element showing where I expect?' for a CSS selector on a live page. Returns the resolved box model, computed display/visibility/opacity/position/z-index, colours, whether the element is inside the viewport, and — crucially — whether another element is covering it. These are the values a browser computes after the full cascade and layout; they cannot be derived from reading HTML and CSS.

  • page_diagnosticsFree

    Load a page in a real browser and report what went wrong: JavaScript console errors and warnings, network requests that failed, and the HTTP status of the page itself. Use this when a site looks broken, a deployment might have shipped a bug, or a page loads blank and you need to know why. An agent cannot see a browser's console any other way.

  • rendered_htmlFree

    Fetch a page's HTML *after* JavaScript has executed. Use this when a plain HTTP fetch returns an empty shell or a loading spinner — single-page apps, sites that build their content client-side, or anything behind a framework. Returns the final DOM as HTML text.

  • screenshot_urlFree

    Take a screenshot of a web page as it actually renders in a real browser, after JavaScript has run. Use this when you need to see a page rather than read it — checking a layout, confirming a site is up and looks right, or capturing what a user would actually see. Returns a PNG image.

  • url_to_pdfFree

    Render a web page to PDF exactly as a browser would print it. Use this to archive a page, produce a document from a rendered report, or capture something for a record. Returns a PDF file.

What the publisher says

From the Render repository's README, as published. We do not edit it. Read it on GitHub

render-mcp

Gives an AI agent a real browser. Screenshots, PDFs, and the HTML a page produces after JavaScript has run.

No API key. No signup. No account. Point your client at a URL and it works.

https://render.makermargins.com/mcp

Why this exists

An agent can fetch a URL. It cannot see one.

Ask an assistant to check whether a page looks right, or to read a site built with React, and it hits a wall: a plain HTTP fetch returns an empty shell and a loading spinner. The content is built by JavaScript that never runs.

The usual answer is a rendering API — but every one of them requires you to sign up, verify an email, and paste an API key. An agent working on its own can't do any of that. It has no inbox and no card. A free tier it cannot register for is worth nothing to it.

This server needs none of it. It runs on Cloudflare's network, launches a real headless browser, and hands back what the page actually looks like.

Install

Claude Code — as a plugin (one command, and updates arrive automatically)

/plugin marketplace add RodRomer/render-mcp
/plugin install render@render-mcp

Claude Code — directly

claude mcp add --transport http render https://render.makermargins.com/mcp

Claude Desktop, Cursor, and other clients — add to your MCP config:

{
  "mcpServers": {
    "render": {
      "type": "http",
      "url": "https://render.makermargins.com/mcp"
    }
  }
}

That's the whole setup. Nothing to install, nothing to configure, no credentials.

Tools

screenshot_url

See a page as a person would. Returns a PNG.

Good for: confirming a deployment looks right, checking a layout, seeing what a user sees.

rendered_html

The DOM after JavaScript has executed. Returns HTML text.

Good for: single-page apps, anything where a plain fetch returns a shell.

page_diagnostics

Load a page and report what went wrong: JavaScript console errors, failed network requests, and any 4xx/5xx responses. Returns a readable summary.

Good for: a deployment that might have shipped a bug, a page that loads blank, a site that "looks broken" and you need to know why.

Stated honestly: this is not a rare capability. Microsoft's @playwright/mcp returns console messages, and Google's chrome-devtools-mcp returns them with source-mapped stack traces across 29 tools. Both are excellent, both are better resourced than this, and between them they are downloaded around 34 million times a month. If you can run a local process, use one of them.

The one thing neither can do is run where nothing can be installed. They need npx, Node, and browser binaries, or a local Chrome. This needs a URL. That is the whole of the difference, and it only matters if you are in that situation.

inspect_element

Answers "why isn't this element showing where I expect?" for a CSS selector.

Shortened. The full README is on GitHub.

Render: common questions

Is Render MCP server safe?
Mostly: it is graded B (75/100). Read the Render safety report
How do I install Render?
It runs remotely at render.makermargins.com. Add it to Claude Code, Cursor, VS Code or Claude Desktop with the snippets above, or call it through the mcp.market gateway without installing anything.
Does Render need an API key?

Is Render maintained?
The last commit was 64 days ago (2026-09-03). The latest release is v0.7.4.
Is Render up?
100% of our last 28 checks got an answer. We check remote servers about four times a day.
What can I use instead of Render?
Servers from other publishers that do the same job: Hwatu MCP server, GrowBlocks Dev Kit MCP server and Slack MCP Server.
How does Render compare with other Scraping and browsing MCP servers?
safety score 75/100 (higher than 42% of 867 Scraping and browsing servers); tools 6 (the typical Scraping and browsing server has 6); tools that change things 17% (typical: 0%. Fewer write tools means less an agent can break). Full comparison.
