WHAT IT DOES

What frida_rpc_call does on Ya Frida

AI agents invoke frida_rpc_call to trigger actions in Ya Frida. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

frida_rpc_call Rate-limited

frida_rpc_call 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.
