MCP QUEEN

Give your AI agent an MCP research layer in one connection.

Add MCP Queen once and let ChatGPT, Claude, Claude Code, or your own agent find better-fit MCP servers before you connect them. Search by what you need done, compare what was actually observed, and keep the answer inside the same conversation.

Stop opening directory tabs, chasing stale repository links, and hand-comparing README claims. MCP Queen brings observed tools, live operational evidence, Trust Receipts, repository-mobility findings, and reviewed field reports into ChatGPT, Claude, or any compatible remote-MCP agent.

ONE CONNECTION No MCP Queen account. No API key. No local install.

What your agent gains

Ask for the job, not a brand

Search observed MCP tool descriptions by capability, even when you do not know which server to look for.

Cut dead ends earlier

See dated reachability, protocol, tool-catalog, latency, and provenance observations before spending time on setup.

Keep evidence in the conversation

Let your assistant retrieve grades, Trust Receipts, caveats, and unaudited gaps while it compares candidates.

Catch stale and moved MCPs

Keep Registry identity, repository location, and remote endpoint separate when projects move, archive, or disappear.

The simple version

1. Copy one URL

Use the public endpoint above. There is no MCP Queen signup or credential to create.

2. Add it to your assistant

Choose the ChatGPT, Claude, Claude Code, or API path below and review the imported tools.

3. Ask naturally

Describe the job. Your assistant can search candidates, inspect evidence, and explain what remains unknown.

Use it inside ChatGPT

Keep MCP research inside the chat where you are already planning, coding, or evaluating tools. Add MCP Queen as a custom MCP app, enable it for a conversation, and ask for candidates in ordinary language.

  1. Open ChatGPT on the web and confirm your account or workspace currently supports custom MCP apps in developer mode.
  2. Enable developer mode, create a custom app, and enter https://mcpqueen.com/mcp as the remote MCP endpoint.
  3. Choose no authentication, scan the tools, and review the imported actions before creating or enabling the app.
  4. Start a new chat, enable MCP Queen, and try one of the evidence prompts below.

Plan availability, workspace roles, and interface labels can change. Check OpenAI's current ChatGPT developer-mode guide. Developers using the API can follow the official remote MCP guide.

Use it inside Claude

Add MCP Queen as a custom connector and let Claude search the MCP ecosystem without leaving your conversation. Claude Code can use the same hosted endpoint from the terminal.

  1. Open Customize → Connectors, select the add control, and choose Add custom connector.
  2. Name it MCP Queen and enter https://mcpqueen.com/mcp.
  3. Finish the setup, enable the connector for a conversation, and test a read-only discovery prompt.

Claude connects to remote custom connectors from Anthropic's cloud. Review Anthropic's current custom-connector instructions and security guidance.

No Docker image or local MCP process is required.

Put MCP discovery inside your own agent

Your agent should not need a separate scraping pipeline or hand-maintained MCP shortlist. Add the hosted endpoint as a remote MCP tool and it can search the Registry, inspect observed capabilities, and retrieve evidence during its existing workflow.

For an OpenAI Responses API agent, explicitly expose only the six read-only discovery and evidence tools. This keeps submit_feedback out of automated research runs.

{
  "type": "mcp",
  "server_label": "mcpqueen",
  "server_description": "Find MCP servers and inspect dated evidence before connecting.",
  "server_url": "https://mcpqueen.com/mcp",
  "allowed_tools": [
    "search_servers",
    "search_tools",
    "list_grades",
    "get_server_grade",
    "get_trust_receipt",
    "search_trust_evidence"
  ],
  "require_approval": "never"
}

Use approval requirements appropriate to your application. Do not send secrets or proprietary data in public MCP Queen search arguments.

Start with one useful question

Find the right tool

“Find MCP servers for Postgres research. For the top three, show the operational grade, Trust Receipt evidence, and everything still unaudited.”

Search by capability

“Search observed MCP tool descriptions for citation export. Return the matching tool, endpoint, latest probe date, and evidence caveats.”

Compare before adopting

“Compare these MCP candidates using dated operational observations and separate security/access evidence. Never turn missing evidence into a pass.”

The payoff: MCP research becomes part of the work instead of a separate scavenger hunt. You keep the speed and context of your existing assistant while MCP Queen supplies a structured discovery and evidence layer.

Discovery without becoming the middleman

MCP Queen helps your assistant narrow the field and explain the evidence. It does not install every server, authorize one, or proxy the final connection.

Find → inspect → decide → connect direct.

  1. Search by task or observed tool capability.
  2. Inspect operational observations, Trust Receipt dimensions, and reviewed field evidence.
  3. State what is observed, provisional, or unaudited.
  4. Evaluate the selected server's own credentials, permissions, terms, and data boundary.
  5. Connect directly to that server in a separate step.

Connection questions

Will MCP Queen work with my AI agent?

If your agent or client supports public remote MCP servers over Streamable HTTP, it can connect to https://mcpqueen.com/mcp. The page includes specific paths for ChatGPT, Claude, Claude Code, and the OpenAI Responses API, plus developer integrations for other agent frameworks.

Can I connect MCP Queen directly to ChatGPT?

Yes, on ChatGPT accounts and workspaces that currently support custom MCP apps in developer mode. Add https://mcpqueen.com/mcp as the remote endpoint, choose no authentication, scan the tools, and review the imported actions before enabling the app. OpenAI plan, role, and interface availability can change, so use the linked official guide for the current gate.

Can I add MCP Queen to Claude without installing software?

Yes. In Claude, add a custom connector named MCP Queen with https://mcpqueen.com/mcp as its remote URL. The endpoint is public and requires no MCP Queen API key. Claude Code also supports the same endpoint with one command.

What does connecting MCP Queen give an assistant?

It gives the assistant tools to search MCP servers and observed tool catalogs, inspect operational grades, retrieve separate Trust Receipts, and search dated trust evidence before a separate direct connection to a selected server.

Does MCP Queen connect to the selected server for me?

No. MCP Queen is the discovery and evidence step. It returns published endpoints and available observations; you or your agent evaluate permissions and then connect directly to the selected server in a separate step.

Do I need an MCP Queen account or API key?

No. The hosted MCP Queen endpoint is public and currently requires no MCP Queen account, API key, local package, or Docker setup. Your chosen AI platform may have its own plan, workspace, or API requirements.
