What your AI can do with Refcat
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “list_facets”: The filter vocabulary with real counts (number of flows): platform, flowIntents, uiComponents, pageType and screenPatterns. Call this before.”
“Use “get_screen”: One catalog screen with its image and structure. Returns an image block (look at it for color, typography and spacing) and JSON with app, fl.”
“Use “search_screens_by_image”: Find catalog screens that look like your images (base64, e.g. a screenshot of the app you are building). Then call get_screen on the matches.”
“Use “search_screens”: Search individual UI screens by description, app name or site ('paywall with annual plan first', 'Spotify', 'linear.app'). Returns metadata.”
How secure is the Refcat MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Refcat holds up.
Official endpoint
Operated by Refcat (refcat.app) 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 Refcat adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps
Connect your gate
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Pick Refcat
Choose Refcat in the gate directory. No sign-in needed.
Use it anywhere
Refcat's tools are live in every AI client you've connected — with rules and logging built in.

Who runs the Refcat MCP server?
The Refcat MCP server at a glance
https://mcp.refcat.app/mcpQuestions, answered
Is there an official Refcat MCP server?
Yes — Refcat operates its own remote MCP server at mcp.refcat.app. 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 Refcat to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Refcat in the directory. No account or sign-in is needed. From then on, Refcat's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Refcat runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Refcat 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 Refcat in minutes. No credit card required.
