List all peripherals configured on the FarmBot. Returns peripheral names, IDs, pin numbers, and modes. Peripherals include the water valve, vacuum pump, lighting, and other connected hardware.
AI agents call farmbot_list_peripherals to retrieve information from Farmbot Agent without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries configuration data about connected hardware (water valve, vacuum pump, lighting, etc.) without creating, modifying, deleting, or executing any operations. It is a pure read operation with no capability to affect the robot's state or perform physical actions.
From the tool's definition Tool name is 'list_peripherals' and description states it 'List[s] all peripherals configured on the FarmBot' and 'Returns peripheral names, IDs, pin numbers, and modes.' The verb 'list' and 'returns' indicate data retrieval with no modification or side…

List all peripherals configured on the FarmBot. Returns peripheral names, IDs, pin numbers, and modes. Peripherals include the water valve, vacuum pump, lighting, and other connected hardware. It is categorised as a Read tool in the Farmbot Agent MCP Server, which means it retrieves data without modifying state.
Register the Farmbot Agent MCP server in PolicyLayer and add a rule for farmbot_list_peripherals: 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_list_peripherals is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the farmbot_list_peripherals 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_list_peripherals. 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_list_peripherals 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.
