Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “search_servers”: Search the MCP evidence registry using a natural multi-word task (e.g. 'reliable no-auth drug interaction server with citations'). Tokenizes.”
“Use “search_tools”: Search across the actual tools that graded MCP servers expose (their tool names and descriptions, captured live from tools/list) — not just.”
“Use “list_grades”: List the top graded MCP servers from the mcpqueen registry (deterministic probe grades with evidence). Returns grade, score 0-100, latency,.”
“Use “get_server_grade”: Get the full grade and verbatim probe evidence for one MCP server, by its official registry name (e.g. 'com.healthai/radar').”
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how MCP Queen holds up.
Operated by MCP Queen (mcpqueen.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 MCP Queen 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 MCP Queen in the gate directory. No sign-in needed.
MCP Queen's tools are live in every AI client you've connected — with rules and logging built in.

https://mcpqueen.com/mcpYes — MCP Queen operates its own remote MCP server at mcpqueen.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 MCP Queen in the directory. No account or sign-in is needed. From then on, MCP Queen's tools are available in every client you've connected to gate.
No. MCP Queen 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 MCP Queen in minutes. No credit card required.
Every server below works through the same gateway URL — connect once, add tools anytime.
