MCP server discovery, comparison, readiness scoring, and validation reports from Sentinel Signal.
Do not connect
The assessed surface is high-risk. Remediate the findings before connecting.
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 MCP Verify MCP server exposes 22 tools, focused primarily on developer capabilities. Its published description reads: "MCP server discovery, comparison, readiness scoring, and validation reports from Sentinel Signal". It communicates over Streamable HTTP using the 2026-07-28 protocol revision, and does not require authorization to connect. MCPGrade currently rates MCP Verify D — the assessed surface is high-risk and should be remediated before use. Its most notable findings include "Cross-tool shadowing" and "Cross-tool shadowing". 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 MCP Verify's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
Add MCP Verify to an MCP client using the endpoint below. Review the grade and findings above before granting an autonomous agent access.
MCP endpoint
https://verify.sentinelsignal.io/mcpStreamable HTTP transport. This is the MCP endpoint, not a website — paste it into your MCP client server list rather than a browser.
Captured passively during the read-only scan. Click any value to find servers that match it.
The tools this server advertises via tools/list — names, purposes, and the parameters each accepts, exactly as enumerated read-only.
ChatGPT-compatible read-only search alias. Returns MCP server results with id, title, and url.
ChatGPT-compatible read-only fetch alias. Returns a full MCP server item with id, title, text, url, and metadata.
Search and rank MCP servers by capability, auth preference, client target, and risk tolerance.
Sorted worst-first. Each finding shows its severity, what it means, its OWASP MCP Top-10 mapping, and a recommended fix — the check id links to the exact methodology row that produced it.
