THE RISK

Why branch needs a policy

The tool explicitly supports deleting branches, which is an irreversible destructive operation. Since the tool spans multiple categories (Read for listing, Write for creating/renaming, Destructive for deleting), the most severe applicable category applies — Destructive. Branch deletion in version control can result in permanent loss of work if not backed up, making severity high.

From the tool's definition Lists, creates, renames, or deletes branches

POLICY

How to control branch

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

policy.json

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

branch 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 Make — 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 branch

What does the branch tool do? +

Lists, creates, renames, or deletes branches. Returns structured branch data. Pass. It is categorised as a Destructive tool in the Make 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 branch? +

Register the Make MCP server in PolicyLayer and add a rule for branch: 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 Make. Nothing to install.

What risk level is branch? +

branch 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 branch? +

Yes. Add a rate_limit block to the branch 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 branch completely? +

Set action: deny in the PolicyLayer policy for branch. 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 branch? +

branch is provided by the Make 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 Make tool call.

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