io.github.RodRomer/render-mcp is an MCP server with 6 tools an agent can call, among them accessibility_audit, inspect_element, page_diagnostics. It answers at https://render.makermargins.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 20 October 2026, succeeded.
Hosted browser for AI agents: screenshots, post-JS DOM, console, WCAG. No install, no API key.

page_diagnostics | 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 Inputs: url, include_warnings, width, height |
rendered_html | 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 fi Inputs: url, wait_for, max_chars |
screenshot_url | 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 u Inputs: url, full_page, width, height |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://render.makermargins.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: io.github.rodromer. Endpoint host: render.makermargins.com. ARD identifier: urn:air:io.github.rodromer:mcp:render-mcp.
First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
