RISK

Why project_list_settings is rated Low

This tool retrieves and queries project settings configuration without modifying, deleting, or executing operations. It is a pure data retrieval operation with no irreversible or external effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs project_list_settings safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Breakpoint, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For project_list_settings, this is the rule to start with:

project_list_settings Allowed

project_list_settings is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Breakpoint, apply this rule, and every project_list_settings call is checked against it from then on.
