Method disconnect_idle_mcp

core/src/agent_api.rs:497–502

Disconnect every global MCP server whose last activity is older than `idle_threshold_ms`. Returns the names of disconnected servers (empty when there is no global MCP manager or when nothing is idle). Hosts running thousands of long-lived sessions should call this periodically (e.g. every 60s with a 5-min threshold) to release file descriptors and background workers from quiet MCP servers without

(&self, idle_threshold_ms: u64)

    /// without losing the server's configuration. A subsequent tool
    /// call on the same server will require an explicit reconnect.
