Get detailed battery monitor data: SOC, voltage, current, power, temperature, cell voltages, time-to-go, history, and alarms. Specify unitId for the battery monitor (check victron_discover to find it).
AI agents call victron_battery_status to retrieve information from Victron Tcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only reads and queries real-time battery status information from the Victron system. It has no side effects, cannot modify system state, execute commands, delete data, or move money. The blast radius of misuse is limited to information disclosure about battery conditions on the local network.
From the tool's definition Tool retrieves battery monitor data (SOC, voltage, current, power, temperature, cell voltages, time-to-go, history, and alarms) from Victron Energy systems with no modification capability.
Attacks that exploit this kind of access
Get detailed battery monitor data: SOC, voltage, current, power, temperature, cell voltages, time-to-go, history, and alarms. Specify unitId for the battery monitor (check victron_discover to find it). It is categorised as a Read tool in the Victron Tcp MCP Server, which means it retrieves data without modifying state.
Register the Victron Tcp MCP server in PolicyLayer and add a rule for victron_battery_status: 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 Victron Tcp. Nothing to install.
victron_battery_status 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 victron_battery_status 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 victron_battery_status. 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.
victron_battery_status is provided by the Victron Tcp MCP server (lubosstrejcek/victron-tcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
