WHAT IT DOES

What worktree does on Test

AI agents call worktree to permanently remove resources in Test — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

THE RISK

Critical Risk

Why worktree needs a policy

The tool performs multiple operations on git worktrees, including 'removes' and 'prunes' which are irreversible destructive actions that can delete working trees and their associated data. While it also supports read (list) and write (add, lock, unlock) operations, the most severe applicable category is Destructive due to the remove/prune capabilities.

From the tool's definition Lists, adds, removes, locks, unlocks, or prunes git worktrees

POLICY

How to control worktree

PolicyLayer is an MCP gateway — it sits between your AI agents and Test, and nothing reaches the server without passing your rules. This is the rule we recommend for worktree:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "worktree"
  ]
}

worktree disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Test — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about worktree

What does the worktree tool do? +

Lists, adds, removes, locks, unlocks, or prunes git worktrees for managing multiple working trees. Returns structured data with worktree paths, branches, and HEAD commits. It is categorised as a Destructive tool in the Test MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on worktree? +

Register the Test MCP server in PolicyLayer and add a rule for worktree: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Test. Nothing to install.

What risk level is worktree? +

worktree is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit worktree? +

Yes. Add a rate_limit block to the worktree rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block worktree completely? +

Set action: deny in the PolicyLayer policy for worktree. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides worktree? +

worktree is provided by the Test MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Test tool call.

Start from Test, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
