pub fn new(global_idle_timeout_minutes: u64) -> Self

pub fn register(&mut self, name: &str, entry: ServerEntry, config_hash: u64)

Register a server definition (from config). Does not connect.

pub async fn ensure_connected(&mut self, name: &str) -> bool

Ensure a server is connected (lazy connect). Returns true if connected/available.

pub fn get_client(&self, name: &str) -> Option<Arc<Mutex<McpClient>>>

Get a connected client for a server (must call ensure_connected first).

pub fn status(&self, name: &str) -> Option<ConnectionStatus>

Get the connection status for a server.

pub fn mark_failed(&mut self, name: &str)

Mark a connection as failed after a tool call error.

pub fn touch(&mut self, name: &str)

Touch a server (update last_used timestamp, e.g. after successful tool call).

pub async fn disconnect(&mut self, name: &str)

Disconnect a server (idle shutdown).

pub async fn close_all(&mut self)

Close all connections (on session shutdown).

pub fn idle_timeout(&self, name: &str) -> Duration

Get the idle timeout for a server (per-server override or global default).

pub async fn sweep_idle(&mut self)

Check for idle servers and disconnect them.

pub fn server_names(&self) -> Vec<String>

Get a list of all registered server names.

pub fn should_connect_eagerly(&self, name: &str) -> bool

Check if a server should be connected eagerly at startup.

pub fn config_hash(&self, name: &str) -> Option<u64>

Get the config hash for a server.
