RECOMMENDED RULE

The rule that runs get_theme 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 get_theme, this is the rule to start with:

get_theme Allowed

get_theme 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": {
    "get_theme": {}
  }
}

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 get_theme call is checked against it from then on.
