defmodule Extools.MCPServer do

  @moduledoc """

  The Extools MCP server definition.



  Uses `Hermes.Server` to expose 12 live-runtime tools over the MCP

  Streamable HTTP transport. The same module backs both the Phoenix Plug

  mode (forwarded from `Extools`) and the standalone Bandit mode.



  On init it installs `Extools.LogHandler` so `get_logs` has a live buffer.
