IPC

Inter-process communication — how processes on the same machine exchange data (pipes, sockets, shared memory).

Definition

Inter-Process Communication covers all mechanisms by which separate processes on the same machine exchange data: Unix domain sockets, named pipes, shared memory, message queues. Claude Code's stdio MCP transport is IPC: the parent process and the server communicate over the child's stdin/stdout pipes. IPC avoids the overhead of full network sockets.
