Module: TalkToYourApp::Transport::RailsMount

Defined in:
lib/talk_to_your_app/transport/rails_mount.rb

Overview

Builds the Rack application the host app mounts. It assembles an MCP::Server from the enabled plugins’ tools, wraps it in the SDK’s Streamable HTTP transport, and fronts the whole thing with the auth middleware. ‘config.stateless` selects the transport’s stateless mode, which holds no per-session state — required when the host app runs more than one worker or replica.
