MCP Queen MCP server

by mcpqueen · official

Lets your AI look up grades and evidence about other MCP servers before you connect to them.

MCP Queen is a public service that checks other MCP servers and publishes dated notes about how they behave. It is handy if you are curious about a new AI helper and want to see what someone else already found out about it. You can use it straight from the web, no account needed.

What is an MCP server? The 30-second version

On its own, your AI can only chat with you. An MCP server is a small helper program that gives your AI a new skill or a connection to an app or service. This one connects your AI to MCP Queen, a public registry that watches other MCP servers and writes down what it sees. So when you ask about a server, your AI can go ask MCP Queen and bring back the answer.

What this MCP server does

You ask your AI something like which MCP servers exist for a certain job. Your AI sends that question to MCP Queen through this helper. MCP Queen looks through its public records of servers, tools, grades and trust receipts, and sends back what it has. Your AI then shows you a short list or a summary in the chat. Everything here is read-only, so nothing on your computer or in your accounts gets changed.

Flow diagram: you ask your AI “Which MCP servers exist for GitHub issue triage?”, the MCP Queen MCP server connects it to MCP Queen, and you get back A short list or summary.

Before you start

What you need

An AI app that can connect to MCP servers, like Claude Code or the Claude desktop app
Nothing else for the hosted web address, since it needs no account

Good to know

A grade here is not a security or privacy certificate, and a server with no evidence is simply unaudited, not proven safe.
