Module host 

The game’s side of shuyi mcp: shuyi mcp-host, run in the game’s tool program, answers the server’s Requests, one JSON line each on stdin, with a Reply line each on stdout, after the mark REPLY. It answers the operations that run the game with the game’s tools, and keeps the session’s game (Host).

InProcess is the same host without a process between, for games’ and the engine’s tests of the server.
