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. The session layer lives entirely in the SDK transport, so a future stateless flip (2026-07-28 RC) is a one-line change here.
