Delete a peripheral. The underlying pin can still be controlled via farmbot_write_pin by number.
AI agents call farmbot_remove_peripheral to permanently remove resources in Farmbot Agent — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes a peripheral device configuration from the FarmBot system. Deletion is inherently irreversible and destructive—once a peripheral is deleted, it must be manually re-added to restore functionality. An AI agent that incorrectly deletes critical peripherals (sensors, actuators, cameras) could disrupt farming operations and require physical intervention to restore.
From the tool's definition The description explicitly states "Delete a peripheral," which is an irreversible operation. Deletion of hardware configuration cannot be undone without manual reconfiguration.
Attacks that exploit this kind of access
Delete a peripheral. The underlying pin can still be controlled via farmbot_write_pin by number. It is categorised as a Destructive tool in the Farmbot Agent MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Farmbot Agent MCP server in PolicyLayer and add a rule for farmbot_remove_peripheral: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Farmbot Agent. Nothing to install.
farmbot_remove_peripheral is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the farmbot_remove_peripheral rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for farmbot_remove_peripheral. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
farmbot_remove_peripheral is provided by the Farmbot Agent MCP server (kieranklaassen/farmbot-agent-cli-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
