Overview

Rack-mountable adapter that exposes the pinmark server over the official ‘mcp` gem’s Streamable HTTP transport. Designed to be mounted inside a Rails router (or any Rack stack), so the standalone Puma process the gem ships is unnecessary.

This class deliberately avoids any Rails-app-specific references (controllers, Current attributes, etc.) so the entire Pinmark::Mcp namespace can later be extracted as a Rails engine / standalone gem.

Constructor Details

#initialize(queue: Queue.new) ⇒ RackApp

Run the transport in stateless mode: every request stands on its own, no per-session state is held in memory. This makes the mount resilient to Rails’ dev-mode code reloading (which can rebuild the mounted Rack instance) and keeps the in-process server cheap to operate. The annotation tools are simple request/response —they do not need streaming notifications.
