MOST DANGEROUS TOOLS

High Risk

The most dangerous Kc Modbus tools

Write · High write_device This tool creates or modifies data on industrial control systems (PLC registers) reversibly. Write · High write_registers This tool writes data to Modbus registers in industrial controllers (PLCs).

2 of Kc Modbus's 8 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Kc Modbus

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

Rate limit write operations

{
  "write_device": {
    "limits": [
      {
        "counter": "write_device_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "device_status": {
    "limits": [
      {
        "counter": "device_status_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 Kc Modbus — 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 Kc Modbus

How do I prevent bulk modifications through Kc Modbus? +

The Kc Modbus server has 2 write tools including write_device, write_registers. 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 Kc Modbus.

How many tools does the Kc Modbus MCP server expose? +

8 tools across 2 categories: Read, Write. 6 are read-only. 2 can modify, create, or delete data.

How do I enforce a policy on Kc Modbus? +

Register the Kc Modbus 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 Kc Modbus tool call.

Deterministic rules across all 8 Kc Modbus tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
