What your AI can do with Polyxd
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “polyxd_guide”: Returns the instructions for writing a Polyxd UI document: the document shape, the rules for generated screens, bindings, actions, every com.”
“Use “polyxd_validate”: Checks a Polyxd UI document against the spec: the schema, ids and references, bindings against the data, actions, and the rules for generate.”
“Use “polyxd_verify”: Runs the Polyxd verifier's document checks: the spec validator, the pattern the surface declares, readable and distinct labels, one primary.”
“Use “polyxd_show”: Validates a Polyxd UI document and shows it to the user as an interactive screen, drawn by the Polyxd renderer in the design-system pack you.”
How secure is the Polyxd MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Polyxd holds up.
Security grade A
gate scanned 6 tools on Oct 1, 2026 for prompt injection and risky tool definitions — nothing to flag.
Official endpoint
Operated by Polyxd (polyxd.com) 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 Polyxd 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 Polyxd MCP server?
The Polyxd MCP server at a glance
https://mcp.polyxd.com/mcpQuestions, answered
Is there an official Polyxd MCP server?
Yes — Polyxd operates its own remote MCP server at mcp.polyxd.com. 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 Polyxd to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Polyxd in the directory. No account or sign-in is needed. From then on, Polyxd's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Polyxd runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Polyxd 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 Polyxd in minutes. No credit card required.
