What your AI can do with CSS SOTA
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “search_css_features”: Search CSS features on the Web Platform Dashboard (webstatus.dev) by keyword, Baseline status, and the date range in which they reached Base.”
“Use “whats_new”: List CSS features that crossed a Baseline threshold within a date range, newest first. Use this to answer "what CSS can I start using now?",.”
“Use “get_feature”: Get everything known about one CSS feature: Baseline status and dates, the browser versions it shipped in, its description, spec links, Web.”
“Use “check_support”: Look up which browser versions support a CSS property, value, selector, at-rule or function, from MDN browser-compat-data bundled with this.”
How secure is the CSS SOTA MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how CSS SOTA holds up.
Official endpoint
Operated by CSS SOTA (pages.dev) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If CSS SOTA adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

Who runs the CSS SOTA MCP server?
The CSS SOTA MCP server at a glance
https://css-sota-mcp.lusrodri.workers.dev/mcpQuestions, answered
Is there an official CSS SOTA MCP server?
Yes — CSS SOTA operates its own remote MCP server at css-sota-mcp.lusrodri.workers.dev. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect CSS SOTA to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick CSS SOTA in the directory. No account or sign-in is needed. From then on, CSS SOTA's tools are available in every client you've connected to gate.
Do I need to host anything?
No. CSS SOTA runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the CSS SOTA MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
Yes — you can get started with gate for free and connect CSS SOTA in minutes. No credit card required.
