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 Microsoft Learn MCP Server MCP server exposes 3 tools, focused primarily on web capabilities. It communicates over Streamable HTTP using the 2026-07-28 protocol revision, and does not require authorization to connect. MCPGrade currently rates Microsoft Learn MCP Server F — a critical issue was found and the server should not be connected as-is. Its most notable findings include "Data-exfiltration parameters" 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 Microsoft Learn MCP Server's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
Add Microsoft Learn MCP Server to an MCP client using the endpoint below. Review the grade and findings above before granting an autonomous agent access.
