RECOMMENDED RULE

The rule that runs add_tts_voice safely

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

add_tts_voice Rate-limited

add_tts_voice 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.
