MCP Queen is the graded MCP registry: evidence-backed server grades from live probes, search, verify, connect.

A critical issue was found. Do not connect this server as-is.
Scanned 1 month ago Due for re-check
A server can change after it's graded. Re-run the automated scan to refresh this report.
This grade is deterministic and reproducible: the same server surface always yields the same grade under a given algorithm version. It is a real automated assessment computed by the MCPGrade engine from what the probe actually observed — not a fabricated or opinion score. It is not a manual human pentest, so it can miss context-specific risks.
Every signal below was measured directly by the automated probe. The grade is derived only from evidence like this — nothing is assumed.
The mcpqueen MCP server exposes 7 tools, focused primarily on general-purpose capabilities. Its published description reads: "MCP Queen is the graded MCP registry: evidence-backed server grades from live probes, search, verify, connect". It communicates over Streamable HTTP using the 2025-06-18 protocol revision, and does not require authorization to connect. MCPGrade currently rates mcpqueen F — a critical issue was found and the server should not be connected as-is. Its most notable findings include "Cross-tool shadowing" and "Database tool takes a raw, unparameterised query". This report is a deterministic, reproducible automated assessment: the same observed surface always yields the same grade under a given algorithm version, and it is refreshed as new scans arrive and free to read — but it is not a substitute for a manual human security review. Always re-check mcpqueen's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
Add mcpqueen to an MCP client using the endpoint below. Review the grade and findings above before granting an autonomous agent access.

tool: search_tools
A database tool exposes a query/sql parameter that is a free-form string with no allow-list or parameterisation constraint — a raw-string injection surface. A tool exposing structured filters or an `enum` of named queries does not fire.
unconstrained query parameter "query"RecommendationExpose parameterised operations instead of a raw query string; never build queries from unvalidated model output.
tool: submit_feedback
A tool exposes a free-text/webhook/feedback parameter with no honest purpose — a classic exfil channel.
