Detailed Description

Native transport-contract client for a child MCP server over stdio.

This class exposes process stdio through transport::ClientTransport while reusing the established client process implementation. send() serializes outbound writes. Sending a request waits for the matching response and queues it for receive(); sending a response completes an inbound server-to-client request previously returned by receive(). receive() blocks until a queued message is available or close() completes. Concurrent receive() calls are not supported.

Member Function Documentation

close()

core::Result< core::Unit > mcp::transport::ProcessStdioClientTransport::close ( )

overridevirtual

Closes the transport and unblocks receive() where possible.

Implements mcp::transport::Transport< Role >.

diagnostics()

protocol::Json mcp::transport::ProcessStdioClientTransport::diagnostics ( ) const

overridevirtual

Structured implementation diagnostics.

The default keeps the core contract narrow. Transports with useful state may return keys such as "name", "closed", "inflight", or backend-specific counters. Diagnostics are not part of the wire protocol.

Reimplemented from mcp::transport::Transport< Role >.

name()

std::string_view mcp::transport::ProcessStdioClientTransport::name ( ) const

overridevirtualnoexcept

Human-readable transport name for diagnostics.

Implements mcp::transport::Transport< Role >.

receive()

core::Result< std::optional< RxMessage > > mcp::transport::ProcessStdioClientTransport::receive ( )

overridevirtual

Receives the next JSON-RPC message from the peer.

receive() is the sequential inbound side. A successful std::nullopt return is an orderly end-of-stream signal, not a parse or transport error.

Implements mcp::transport::Transport< Role >.

send()

core::Result< core::Unit > mcp::transport::ProcessStdioClientTransport::send ( TxMessage  message )

overridevirtual

Sends one JSON-RPC message to the peer.

Concurrency safety is implementation-specific and must be documented by the concrete transport.

Implements mcp::transport::Transport< Role >.
