MCP Queen MCP server

Which servers in the official MCP registry are MCP Queen's own, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry namecom.mcpqueen/registryverified in the MCP registry

The registry name sits under mcpqueen.com. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-24 the server answered initialize and tools/list without a sign-in. First answer in 16 ms.

Should an agent connect itNot proven either way yet
  • Its tools do every use case we checked: find MCP servers and inspect their observed tools; review dated operational evidence before connecting a server.
  • Checked on 3 of the 7 days it takes to judge reliability.

Once connected

  • For "find MCP servers and inspect their observed tools", the likely first call is search_servers.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

What an agent can do with it

  • can do · find MCP servers and inspect their observed tools
  • can do · review dated operational evidence before connecting a server
  • not sure · compare MCP servers by use case such as databases or dev tools

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

None of the five warning signs in these definitions.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

  • search_servers

    Search the MCP evidence registry using a natural multi-word task (e.g. 'reliable no-auth drug interaction server with citations'). Tokenizes and expands common synonyms, ranks metadata plus observed tool descriptions, and supports…

  • search_tools

    Search across the actual tools that graded MCP servers expose (their tool names and descriptions, captured live from tools/list) — not just server metadata. Use this when you need a specific capability or data type, e.g. 'get weather'…

  • list_grades

    List the top graded MCP servers from the mcpqueen registry (deterministic probe grades with evidence). Returns grade, score 0-100, latency, tool count and auth state per server.

  • 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').

  • get_trust_receipt

    Get one MCP server's complete evidence receipt: operational grade, deterministic security/data-integrity/citation/claim observations, and reviewed real-usage field reports. Missing observations are explicitly unaudited, never treated as a…

  • search_trust_evidence

    Search published MCP trust evidence and reviewed real-usage field reports. Use for questions such as which servers expose citations, have access caveats, make unverifiable corpus claims, or show security concerns. Returns verbatim…

  • submit_feedback

    Submit a field report about an MCP server you have actually used (what worked, what failed, surprising behavior). Reports are quarantined for human review and never auto-published.

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "registry": {
      "type": "http",
      "url": "https://mcpqueen.com/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http mcpqueen https://mcpqueen.com/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://mcpqueen.com/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
