Query a server
AI agents call hetzner_get_server_ram to retrieve information from Hetzner MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves server resource information (RAM). It performs a read-only operation with no side effects, no code execution, no data modification, and no destructive actions. The low severity reflects that exposing server metrics to an AI agent presents minimal risk—the agent gains visibility into infrastructure state but cannot alter it or trigger operations.
From the tool's definition Tool name 'hetzner_get_server_ram' and description 'Query a server' indicate retrieval of server information (RAM metrics) without modification or execution.

Yes. Add a rate_limit block to the hetzner_get_server_ram 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.
