struct mcp.Instance struct [source] ¶ struct [source] ¶ struct mcp.Instance

Instance owns the SDK server, all connected client sessions, and every resource allocated on their behalf. The SDK server is composed so Connect and Run cannot bypass lifecycle tracking.

Connect

Connect ( ctx : context.Context , transport : sdk.Transport , options : *sdk.ServerSessionOptions ) → (*ServerSession, error) method [source] ¶ method [source] ¶ Connect

Connect starts and tracks one client session. It requires tmux 3.2a or newer and rejects an opaque transport unless AssumeResponseCommit marks its response-write contract. Incoming messages remain gated until the SDK session has an installed scope.

Run

Run ( ctx : context.Context , transport : sdk.Transport ) → error method [source] ¶ method [source] ¶ Run: Run serves one tracked session until the client, context, or instance ends. Its transport requirements are the same as Instance.Connect .

Close

Close ( ) → error method [source] ¶ method [source] ¶ Close: Close starts shutdown and waits on a bounded internal context.

CloseContext

CloseContext ( ctx : context.Context ) → error method [source] ¶ method [source] ¶ CloseContext: CloseContext starts shutdown unconditionally. ctx bounds only this call's wait; a later call can resume waiting for the same shutdown.
