RECOMMENDED RULE

The rule that runs app_send_keys safely

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

app_send_keys Rate-limited

app_send_keys 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.
