RECOMMENDED RULE

The rule that runs ui_keyboard safely

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

ui_keyboard Rate-limited

ui_keyboard 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.
