Interface IMcpTransport
Defines the transport layer abstraction for MCP (Model Context Protocol) communication.
public interface IMcpTransport : IDisposable- Inherited Members
Remarks
Implementations handle the low-level message exchange with MCP servers using different transport mechanisms. The MCP specification supports multiple transport types:
- HTTP + SSE: HTTP POST for requests, Server-Sent Events for notifications
- Stdio: Process-based communication via stdin/stdout (JSONL format)
- Custom: WebSocket, Unix sockets, or other mechanisms
All transport implementations must be thread-safe for concurrent request/notification operations.
Properties
- IsConnected
Gets whether the transport connection is currently established and ready for communication.
- TransportType
Gets the transport type identifier for logging and diagnostics.
Methods
- CloseAsync(CancellationToken)
Closes the transport connection gracefully.
- ConnectAsync(CancellationToken)
Establishes the transport connection asynchronously.
- SendNotificationAsync(string, object, CancellationToken)
Sends a JSON-RPC notification (fire-and-forget, no response expected).
- SendRequestAsync(long, string, object, CancellationToken)
Sends a JSON-RPC request and waits for the corresponding response.
Events
- Disconnected
Raised when the transport connection is unexpectedly lost.
- ServerNotificationReceived
Raised when a server-initiated notification is received.
