{"name":"render-mcp","title":"Render — a real browser for agents","version":"0.6.1","description":"An MCP server that gives AI agents a real browser. Screenshots, PDFs, and post-JavaScript HTML. No API key, no signup.","endpoint":"https://render.makermargins.com/mcp","transport":"streamable-http","tools":[{"name":"screenshot_url","description":"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."},{"name":"rendered_html","description":"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."},{"name":"page_diagnostics","description":"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."},{"name":"accessibility_audit","description":"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."},{"name":"inspect_element","description":"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."},{"name":"url_to_pdf","description":"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."}]}
