What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Optional settings from the registry entry, left out of the block above:
VENT_LIVE (Set to 1 for live mode: the agent can look at and use any running app through its accessibility tree, and save steps that worked as a tool once you approve them. Sends, deletes and the like ask you first), VENT_ALLOW_HIGH (Set to 1 to run tools a pack marks as high risk without asking. Without it, they're offered only to clients that can ask you to confirm each call (MCP elicitation)), VENT_HEAL (Set to 1 to let the server call a model to re-ground broken anchors. Off keeps serving model-free), VENT_HOME (Directory for your own packs and traces. Defaults to ~/.ventriloquist), VENT_READ_ONLY (Set to 1 to serve read-only tools only. Every other call is refused, even with VENT_ALLOW_HIGH), VENT_NO_VALUES (Set to 1, together with VENT_HEAL=1, to keep field values out of what the healer sends to the model).
