Get solar charger data: PV voltage, current, power, yield today/yesterday/total, charger state, error code, and tracker data. Specify unitId for the solar charger (check victron_discover to find it).
AI agents call victron_solar_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 retrieves real-time telemetry and status information from a Victron solar charger system without any side effects or data modification capabilities. It is a straightforward sensor data query operation with no destructive, financial, or execution implications. Low severity reflects the limited blast radius of querying energy system metrics.
From the tool's definition Tool description explicitly states 'Get solar charger data' with read-only outputs: PV voltage, current, power, yield metrics, charger state, error code, and tracker data. No mention of modifying, deleting, or executing operations.
Attacks that exploit this kind of access
Get solar charger data: PV voltage, current, power, yield today/yesterday/total, charger state, error code, and tracker data. Specify unitId for the solar charger (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_solar_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_solar_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_solar_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_solar_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_solar_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.
