SEC590 / MCP-AUTOAPPROVE-PNPM-DLX ​

SEC590 flags MCP configuration when autoApprove includes a Bash(pnpm dlx ...) tool token.

Why It Matters ​

pnpm dlx runs packages from a mutable registry path. Auto-approving it removes review from dynamic package execution.

Trigger Shape ​

  • the file is a detected MCP configuration surface
  • autoApprove is a string array
  • the array contains an item starting with Bash(pnpm dlx

How To Fix ​

Remove shared pnpm dlx auto-approval and keep mutable package execution under explicit user review.
