class

Smith::MCP::Client

Inherits Reference < Object

A single MCP server connection: handshake, tool list, tool calls.

One reader fiber owns the stream and hands each response to whoever is waiting on that id. Nothing else may read from the transport — requests overtake each other routinely, and matching by arrival order instead of by id is exactly the bug that produces silently swapped tool results.

Constants

DEFAULT_TIMEOUT = 60.seconds

STARTUP_TIMEOUT = 10.seconds

The handshake gets its own, shorter deadline. A command that is not an MCP server at all — a typo, a plain cat — never answers, and the whole session start would otherwise wait out the full call timeout for it.

Constructors
