What your AI can do with uCAD
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “specs”: Call this FIRST in every session, before writing any uCAD script, even if you have notes or a skill about uCAD from before: the language (a.”
“Use “example”: The script of one of the reference examples listed by specs (by its id): a finished model built carefully in uCAD's language, to learn from.”
“Use “run_script”: Run a whole uCAD script on a drawing in the user's account (a new drawing when `drawing` is left out) and keep the result there. Returns the.”
“Use “view”: Pictures of a drawing as it is now (with anything the user changed by hand), from the sides asked for.”
How secure is the uCAD MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how uCAD holds up.
Security grade A
gate scanned 7 tools on Nov 9, 2026 for prompt injection and risky tool definitions — nothing to flag.
Official endpoint
Operated by uCAD (ucad.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 uCAD 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 uCAD
Choose uCAD in the gate directory. No sign-in needed.
Use it anywhere
uCAD's tools are live in every AI client you've connected — with rules and logging built in.

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