What your AI can do with PromptUI
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “echo”: Echo back the input (for testing MCP integration).”
“Use “web_scout”: Research the live web: search for information, read documentation, fetch API references, or verify library usage. Returns structured finding.”
“Use “shadcn_ui”: Get production-quality shadcn/ui component code pre-adapted for the Sandpack preview environment. Available components: accordion, dropdown_.”
“Use “build_app”: Build a working web app from a prompt with PromptUI. Starts an asynchronous build (costs credits from the authenticated account) and returns.”
How secure is the PromptUI MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how PromptUI holds up.
Official endpoint
Operated by PromptUI (promptui.co) 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 PromptUI 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 PromptUI
Choose PromptUI in the gate directory. No sign-in needed.

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