WHAT IT DOES

What camera_snapshot does on Ha Nexus Agent

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

RISK

Why camera_snapshot is rated Low

This tool retrieves a still image from a camera — it reads/fetches data without modifying any state or causing side effects. The main concern is privacy (capturing video feed), but operationally it is a read-only action.

RECOMMENDED RULE

The rule that runs camera_snapshot safely

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

camera_snapshot Allowed

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

policy.json

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

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

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