WHAT IT DOES

What crow_plex_play does on Crow

AI agents invoke crow_plex_play to trigger actions in Crow. 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.

RISK

Why crow_plex_play is rated High

This tool initiates playback on a Plex media client, which is an operational trigger with side effects on external infrastructure. It does not read/retrieve data passively (that would be Read), nor does it create/modify persistent data structures (Write). Instead, it commands an external system to perform an action.

From the tool's definition Tool performs 'Start playback of an item on a Plex client' — an external operation that triggers media playback, a side effect dependent on provided arguments (client_id, item). While not destructive or financial, it executes actions on external systems.

RECOMMENDED RULE

The rule that runs crow_plex_play safely

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

crow_plex_play Rate-limited

crow_plex_play 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.
