Crate rust_mcp_transport

Modules§

ClientSseTransport: Client-side Server-Sent Events (SSE) transport implementation
ClientSseTransportOptions: Configuration options for the Client SSE Transport
ClientStreamableTransport
MessageDispatcher: Provides a dispatcher for sending MCP messages and handling responses.
RequestOptions
SseEvent: Represents a single Server-Sent Event (SSE) as defined in the SSE protocol.
SseTransport
StdioTransport: Implements a standard I/O transport for MCP communication.
StreamableTransportOptions
TransportOptions: Configuration for the transport layer

IoStream: Enum representing a stream that can either be readable or writable. This allows the reuse of the same traits for both MCP Server and MCP Client, where the data direction is reversed.

DEFAULT_MAX_LINE_LENGTH: Maximum size (in bytes) of a single newline-delimited incoming message for all transports (stdio, SSE, streamable HTTP). Messages exceeding this limit are dropped silently; increase this value if you expect large tool results or responses.
MCP_LAST_EVENT_ID_HEADER
MCP_METHOD_HEADER: SEP-2243 standard request header naming the JSON-RPC method of the request body (e.g. tools/call). Required on the 2026-07-28 stateless wire.
MCP_NAME_HEADER: SEP-2243 standard request header naming the tool/prompt/resource the request targets (params.name or params.uri), when the method has one.
MCP_PROTOCOL_VERSION_HEADER
MCP_SESSION_ID_HEADER

McpDispatch: A trait for dispatching MCP (Message Communication Protocol) messages.
Transport: A trait representing the transport layer for the MCP (Message Communication Protocol).
TransportDispatcher: A composite trait that combines both transport and dispatch capabilities for the MCP protocol.

EventId
RequestHeaderProvider: Hook computing extra HTTP headers for a given outgoing POST payload (e.g. SEP-2243 Mcp-Param-* mirroring, rotating bearer tokens).
SessionId
StreamId
