MOST DANGEROUS TOOLS

High Risk

The most dangerous Zont tools

Execute · High send_custom_command The name 'send_custom_command' strongly suggests this tool sends arbitrary or user-defined commands to the heating system, which falls under Execute. Write · High set_heating_mode_all The name suggests writing/updating heating mode configuration for all devices simultaneously. Write · High set_dhw_temperature This tool modifies a critical heating system parameter (DHW temperature). Write · High set_guard_zone This tool modifies the armed/disarmed state of a security guard zone.

10 of Zont's 26 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Zont

PolicyLayer is an MCP gateway — it sits between your AI agents and Zont, and nothing reaches the server without passing your rules. These are the rules we recommend:

Rate limit write operations

{
  "set_dhw_temperature": {
    "limits": [
      {
        "counter": "set_dhw_temperature_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "diagnose_heating": {
    "limits": [
      {
        "counter": "diagnose_heating_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Create a free account and register Zont — nothing to install.
Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about Zont

How do I prevent bulk modifications through Zont? +

The Zont server has 9 write tools including set_dhw_temperature, set_guard_zone, set_heating_mode. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach Zont.

How many tools does the Zont MCP server expose? +

26 tools across 2 categories: Read, Write. 16 are read-only. 10 can modify, create, or delete data.

How do I enforce a policy on Zont? +

Register the Zont MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every Zont tool call.

Deterministic rules across all 26 Zont tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
