suggest_worktrees · Claude Team MCP: Risk & Policy

WHAT IT DOES

What suggest_worktrees does on Claude Team MCP

AI agents invoke suggest_worktrees to trigger actions in Claude Team MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why suggest_worktrees needs a policy

The tool produces executable git commands as output. While git worktree itself is not destructive (changes are isolated and reversible), executing arbitrary git commands falls under Execute category.

From the tool's definition Tool generates and provides 'ready-to-run git worktree commands' — these are shell commands intended for execution. git worktree creates isolated working directories that modify the local repository state.
