SEC620 / MCP-AUTOAPPROVE-EDIT ​

SEC620 flags MCP configuration when autoApprove includes the exact bare tool token Edit.

Why It Matters ​

Bare Edit auto-approval grants unreviewed file modification authority without narrowing access to specific repository paths.

Trigger Shape ​

This rule matches parsed McpConfig content where autoApprove contains the exact string Edit.

How To Fix ​

Replace bare Edit auto-approval with narrower reviewed scopes such as Edit(./docs/**) or remove shared auto-approval for file edits.
