MCP Queen: MCP server, setup and security
MCP Queen is an open-source MCP server that lets an AI agent inspect MCP server grades based on live operational probes. Its repository has 1 stars and its last commit is from September 13, 2026 and it is licensed under MIT.
What MCP Queen does
According to its repository: “Graded MCP registry: live-probes remote servers from the MCP Registry (initialization, tool listing, schema quality, latency, provenance) and publishes grades.”
An MCP server gives an AI agent extra tools it calls during the conversation: the agent reads their description, decides to use them and gets the result back. MCP Queen is listed under Aggregators and gateways, a category of 141 servers in the directory, where it ranks #131 by stars.
Topics declared by the repository: agent-tools, mcp-registry.
Installing and connecting MCP Queen
Distribution modes declared in the official MCP registry:
- remote server (streamable-http): you connect to it by URL, with nothing to install locally
Like any MCP server, you declare it in your client's configuration (Claude Desktop, Claude Code, Cursor, VS Code, Codex…): a name, the command that starts it or its URL, and any environment variables. The client then starts it and lists its tools. Project language: TypeScript.
Security: what to check
An MCP server runs code with the rights you give it, and the model reads its tool descriptions: a malicious or compromised server can hijack the agent. Read the code, or pick a maintained and widely used server, before connecting it.
None of the risk signals we track (system access, secrets, missing licence, abandonment) applies to MCP Queen. That does not replace reading the code.
Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.
Project activity and maintenance
Created on July 12, 2026, the mcpqueen/mcpqueen repository has 1 stars and 0 forks, with 1 open issues. It has more stars than 7% of the servers in the directory. Last change 1 month ago. Version published in the registry: 0.3.0 (July 28, 2026).
Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
