RECOMMENDED RULE

The rule that runs start_options_flow safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Ha Nexus Agent, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For start_options_flow, this is the rule to start with:

start_options_flow Rate-limited

start_options_flow stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
