Is Microsoft Learn MCP safe?
- Node.js shell/command execution
- MCP tool surface detected
repo is an AI mcp_server analyzed by SkillTotal's deterministic static scanner. The scan found no malicious indicators, though 2 risky constructs are reported for review. It can: mcp tools detected and shell execution — capabilities are what the code can do, not a verdict on intent. Risk score 0/100 (low).
repo
Automated static-analysis result. It can contain false positives and false negatives, and is not a claim about the intent of Microsoft Learn MCP's authors. Report a false positive.
Behavioral traits
How this component maps to the CSA agentic threat model. Descriptive — it never affects the risk score.
Findings (2)
The component can run operating-system commands or spawn processes.
const match = HEADING_PATTERN.exec(line);
const match = HEADING_PATTERN.exec(lines[index] ?? '');
Why it matters: Powerful and often legitimate — confirm the commands aren't built from untrusted input.
Fix: Confirm the command and its arguments are fully controlled and not derived from untrusted input; prefer execFile with an argument array.
An MCP tool surface (manifest or tool definitions) was found.
"mcpServers": {Why it matters: Just context — review which tools it offers and their permissions.
Fix: Review the declared MCP tools and their permissions.
