## What it 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.

## Requirements
- Remote server: `https://mcpqueen.com/mcp`

## When to use it
- 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
- 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
