WHAT IT DOES

What service_list does on Nasbridge

AI agents call service_list to retrieve information from Nasbridge without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why service_list is rated Low

This is a pure read operation that queries and returns service status information. It has no side effects—it does not create, modify, delete, or execute any system changes. The blast radius of misuse is minimal since an agent can only view information, not alter system state. Low severity is appropriate for reconnaissance-only access.

From the tool's definition Tool name 'service_list' and description 'List all system services with their current status (running/stopped) and whether they are enabled at boot' indicate a query operation that retrieves service status information without modifying, deleting, or executing…

RECOMMENDED RULE

The rule that runs service_list safely

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

service_list Allowed

service_list 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": {
    "service_list": {}
  }
}

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

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