Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “score_prompt”: Score a prompt's quality across 8 dimensions BEFORE sending it to an expensive model. Returns a 0-80 score, an A-F grade, the per-dimension.”
“Use “optimize_prompt”: Rewrite a prompt to score higher on the PQS rubric, AND show before/after output comparisons so the user can see the impact. Returns the opt.”
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Pqs MCP Server holds up.
Operated by Pqs MCP Server (promptqualityscore.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
This server only exposes public data — no account and no credentials are involved when you connect.
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
If Pqs MCP Server adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Choose Pqs MCP Server in the gate directory. No sign-in needed.
Pqs MCP Server's tools are live in every AI client you've connected — with rules and logging built in.

https://promptqualityscore.com/api/mcpYes — Pqs MCP Server operates its own remote MCP server at promptqualityscore.com. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
Add gate's gateway URL to your AI client once, then pick Pqs MCP Server in the directory. No account or sign-in is needed. From then on, Pqs MCP Server's tools are available in every client you've connected to gate.
No. Pqs MCP Server runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
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.
Yes — you can get started with gate for free and connect Pqs MCP Server in minutes. No credit card required.
