@spec build_capabilities(module(), String.t() | nil) :: map()

Builds server capabilities object based on protocol version.

Returns version-specific capabilities from the VersionRegistry. Handlers can still override this in their handle_initialize/2 if they want to advertise different capabilities.

Parameters

• handler_module: The handler module (reserved for future use)
• version: The negotiated protocol version (defaults to latest)

Examples

iex> ExMCP.Server.Capabilities.build_capabilities(MyHandler, "2025-03-26")
%{
  "prompts" => %{"listChanged" => true},
  "resources" => %{"subscribe" => true, "listChanged" => true},
  "tools" => %{},
  "logging" => %{"setLevel" => true},
  "completion" => %{},
  "experimental" => %{}
}
