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 Crypto Technical Features MCP server exposes 18 tools, focused primarily on general-purpose capabilities. Its published description reads: "Crypto market technical indicators and sentiment analysis for blockchain assets". It communicates over Streamable HTTP using the 2025-06-18 protocol revision, and does not require authorization to connect. MCPGrade currently rates Crypto Technical Features F — a critical issue was found and the server should not be connected as-is. Its most notable findings include "Metadata dictates tool-call ordering" and "Data-exfiltration parameters". 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 Crypto Technical Features's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
Add Crypto Technical Features to an MCP client using the endpoint below. Review the grade and findings above before granting an autonomous agent access.
