MCP Queen — Claude Code MCP server: what it does, how to install
An evidence service providing operational track records and Trust Receipts for Model Context Protocol servers via an open HTTP endpoint.
claude mcp add --transport http registry https://mcpqueen.com/mcpWhat MCP Queen does
MCP Queen indexes Model Context Protocol registries over a public Streamable HTTP interface at https://mcpqueen.com/mcp. It supplies six read-only tools to inspect registries (search_servers, search_tools), retrieve run scores (list_grades, get_server_grade), and review verification traces (get_trust_receipt, search_trust_evidence). A separate submit_feedback tool queues community notes into an isolated review hold.
Operational grades strictly reflect runtime observations and do not certify code security, privacy safeguards, or regulatory conformance. When an IDE client lacks direct HTTP connectivity, this repository supplies a zero-dependency Node.js bridge and Dockerfile that pipe local stdio commands straight to the hosted endpoint.
What it helps with
- search for Model Context Protocol tools via
search_servers - inspect operational marks before mounting an unverified server
- retrieve dated Trust Receipts to evaluate external tool evidence
- bridge remote Streamable HTTP traffic through local stdio or Docker
Example prompts for the agent
- Find Model Context Protocol servers for GitHub issue triage using MCP Queen
- Check operational grades and trust receipts for a target server
- List documented tools matching database migrations in MCP Queen

Questions about MCP Queen
How do I install MCP Queen in Claude Code?
Run claude mcp add --transport http mcp-queen https://mcpqueen.com/mcp. Claude Code connects directly to the remote URL without an account.
What does MCP Queen do?
It gives coding agents discovery tools to search public servers, inspect metadata, and review empirical grades. Developers can verify an integration's operational history before adopting it.
Does an operational grade mean a server is completely secure?
No, these metrics indicate recorded runtime checks rather than formal security audits or privacy certifications. Missing evidence flags an uninspected integration rather than a safe one.
