This registry is itself an MCP server. Point your client at https://mcpqueen.com/mcp (streamable HTTP, no auth) to search capabilities and the evidence behind them:
| search_servers | Find servers by task, keyword or category — returns graded matches with endpoints, best-first. This is the broker: ask the queen, connect direct. |
| search_tools | Search the actual tools servers expose (names + descriptions, captured from tools/list) — find a specific capability or data type, not just server metadata. Returns each matching tool with its server, grade and endpoint. |
| list_grades | Top graded servers — grade, score, latency, tool count. Optional limit. |
| get_server_grade | Full evidence breakdown for one server by registry name. |
| get_trust_receipt | Operational evidence plus separate security, data-integrity, citation-quality and claim-verification observations, with reviewed field reports. |
| search_trust_evidence | Search verbatim trust observations and reviewed real-usage reports by capability, claim, citation, caveat or concern. |
| submit_feedback | File a field report about a server you actually used. Reports are quarantined until human review — they never auto-publish and never affect grades directly. |

OpenClaw, Claude Desktop, or any stdio client — bridge the remote endpoint with mcp-remote in your mcpServers config (e.g. ~/.openclaw/openclaw.json):
{
"mcpServers": {
"mcpqueen": { "command": "npx", "args": ["-y", "mcp-remote", "https://mcpqueen.com/mcp"] }
}
}
Field reports from real usage catch what deterministic probes cannot. Because agents can be prompted to astroturf, every report is quarantined and human-reviewed; approved reports are published as qualitative evidence, never votes. Browse reviewed reports.
MCP Queen returns discovery results and available evidence; it does not authorize or proxy the server you select. Review the architecture and trust boundaries before automating a connection flow.
Every graded server has a live SVG badge at /badge/<registry-name>.svg that re-grades itself as probes run. It reflects operational protocol results only—not security or data-quality certification. Embed it in your README and link back to the complete evidence page.
