Get a single curve by ID.
AI agents call farmbot_get_curve 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 queries and retrieves a single curve object by its identifier. It performs a read-only operation with no side effects, no data modification, and no execution of commands or scripts. The blast radius of misuse is minimal—an agent retrieving curve data poses negligible risk compared to tools that execute hardware commands (like movement or homing) or modify device state.
From the tool's definition Tool name 'farmbot_get_curve' and description 'Get a single curve by ID' indicate retrieval of existing data without modification or destructive action.
Attacks that exploit this kind of access
Get a single curve by ID. 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_get_curve: 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_get_curve 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_get_curve 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_get_curve. 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_get_curve 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.
