 You can add any custom headers needed for your authentication scheme, or for any other purpose. The client will include these headers on every request.
 
+#### Customizing the Faraday Connection
+
+You can pass a block to `MCP::Client::HTTP.new` to customize the underlying Faraday connection.
+The block is called after the default middleware is configured, so you can add middleware or swap the HTTP adapter:

+```ruby
+http_transport = MCP::Client::HTTP.new(url: "https://api.example.com/mcp") do |faraday|
+  faraday.use MyApp::Middleware::HttpRecorder
+  faraday.adapter :typhoeus
+end
