Current snapshot: latest production power (W), today's energy so far (Wh),
AI agents call get_system_summary 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 real-time and aggregated solar production metrics without side effects. It is a simple data query operation that reads telemetry from the Enphase API. The blast radius of misuse is minimal—an agent could only obtain visibility into solar system performance data, which is not sensitive enough to warrant a higher severity classification.
From the tool's definition Tool name 'get_system_summary' and description indicate retrieval of current snapshot data: 'latest production power (W), today's energy so far (Wh)'. No modification, deletion, or execution indicated.
Attacks that exploit this kind of access
Current snapshot: latest production power (W), today's energy so far (Wh),. 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_system_summary: 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_system_summary 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_system_summary 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_system_summary. 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_system_summary 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.
