Battery telemetry: state of charge (%), charging power, discharging power.
AI agents call get_battery_telemetry to retrieve information from Enphase Solar MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves telemetry data about a battery's operational state (charge level, power flows). It does not modify settings, execute commands, delete data, or move money. The description explicitly states only data retrieval. The server documentation confirms optional write tools exist separately (battery settings, EV charging), implying this tool is read-only.
From the tool's definition Tool name 'get_battery_telemetry' and description 'Battery telemetry: state of charge (%), charging power, discharging power' indicate a retrieval operation that queries current battery status metrics with no side effects or modifications.
Attacks that exploit this kind of access
Battery telemetry: state of charge (%), charging power, discharging power. It is categorised as a Read tool in the Enphase Solar MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Enphase Solar MCP Server MCP server in PolicyLayer and add a rule for get_battery_telemetry: 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 Enphase Solar MCP Server. Nothing to install.
get_battery_telemetry 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 get_battery_telemetry 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 get_battery_telemetry. 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.
get_battery_telemetry is provided by the Enphase Solar MCP Server MCP server (xianman/enphase-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
