THE RISK

Why fleet_testflight_builds needs a policy

This tool performs a read operation returning a list of builds or build metadata. There are no side effects, data modifications, deletions, code execution, or financial implications. The blast radius of misuse is minimal - an agent could gather information about app builds but cannot alter infrastructure, trigger deployments, or perform destructive actions.

From the tool's definition Tool description states 'List an app' - a query operation that retrieves information without modification. The tool name 'fleet_testflight_builds' indicates it retrieves TestFlight build information.

POLICY

How to control fleet_testflight_builds

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "fleet_testflight_builds": {}
  }
}

fleet_testflight_builds is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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