AI agents call get_event_types 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 static reference data (event type definitions) from the Enphase API without modifying any system state, querying user data, or triggering operations. It is a simple reference lookup with no side effects, fitting the 'Read' category. Severity is low as the data appears to be system metadata rather than sensitive user data, and there is no capability to modify or delete information.
From the tool's definition Tool name 'get_event_types' and description indicate a reference list retrieval operation. The description states 'list of event_type_id values with their descriptions' - a purely informational, read-only lookup.

Register the Enphase Solar MCP Server MCP server in PolicyLayer and add a rule for get_event_types: 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_event_types 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_event_types 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_event_types. 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_event_types 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.
