MOST DANGEROUS TOOLS
Critical Risk

The most dangerous Farmbot Agent tools

Destructive · High farmbot_remove_farm_event This tool irreversibly deletes farm events that have been scheduled. Destructive · High farmbot_remove_image This tool permanently removes image data from FarmBot's system. Destructive · High farmbot_remove_peripheral This tool permanently removes a peripheral device configuration from the FarmBot system. Destructive · High farmbot_remove_plant This tool removes plant records from the FarmBot garden with no undo mechanism.

45 of Farmbot Agent's 79 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Farmbot Agent

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

Deny destructive operations
{
  "farmbot_remove_farm_event": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

Destructive tools should never be available to autonomous agents without human approval.

Rate limit write operations
{
  "farmbot_add_farm_event": {
    "limits": [
      {
        "counter": "farmbot_add_farm_event_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations
{
  "farmbot_get_curve": {
    "limits": [
      {
        "counter": "farmbot_get_curve_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

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

DESTRUCTIVE 10 tools
Destructive farmbot_remove_farm_event Remove a scheduled farm event by its ID. Permanently deletes the event. Use farmbot_list_farm_events first to Destructive farmbot_remove_image Delete a single image by ID. Destructive farmbot_remove_peripheral Delete a peripheral. The underlying pin can still be controlled via farmbot_write_pin by number. Destructive farmbot_remove_plant Remove a plant from the FarmBot garden by its ID. Permanently deletes the plant point. Use farmbot_list_plant Destructive farmbot_remove_point Remove any point (plant, weed, generic marker) by ID. Permanently deletes the point. Tool slots cannot be rem Destructive farmbot_remove_point_group Delete a point group by ID. Does not delete the underlying points. Destructive farmbot_remove_regimen Delete a regimen by ID. Removes the schedule but does not delete the underlying sequences. Destructive farmbot_remove_sensor Delete a sensor. Destructive farmbot_remove_sequence Delete a sequence by ID.

Questions about Farmbot Agent

Can an AI agent delete data through the Farmbot Agent MCP server? +

Yes. The Farmbot Agent server exposes 10 destructive tools including farmbot_remove_farm_event, farmbot_remove_image, farmbot_remove_peripheral. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.

How do I prevent bulk modifications through Farmbot Agent? +

The Farmbot Agent server has 23 write tools including farmbot_add_farm_event, farmbot_add_peripheral, farmbot_add_plant. 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 Farmbot Agent.

How many tools does the Farmbot Agent MCP server expose? +

79 tools across 4 categories: Destructive, Execute, Read, Write. 34 are read-only. 45 can modify, create, or delete data.

How do I enforce a policy on Farmbot Agent? +

Register the Farmbot Agent 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 Farmbot Agent tool call.

Deterministic rules across all 79 Farmbot Agent tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
