  # ── MCP server ─────────────────────────────────────────────────────────────
  # Transport is controlled by MCP_TRANSPORT in .env (stdio | streamable-http | sse).
  #
  # stdio mode (default):
  #   NOT started by `docker compose up` — spawned on demand by agent.py:
  #     docker compose run --rm mcp-server
  #   The -i flag (stdin open) is required for the stdio JSON-RPC pipe.
  #
  # HTTP mode:
  #   Set PROXMOX_MCP_TRANSPORT=streamable-http in .env, then:
  #     docker compose up mcp-server
  #   Endpoint: http://<host>:PROXMOX_MCP_HTTP_PORT/mcp (default 0.0.0.0:8080).
  #   PROXMOX_MCP_TRANSPORT=sse is the legacy transport (endpoint /sse).

  # Interactive CLI agent backed by a local or remote Ollama instance.

  # Usage (Ollama on the same machine as Docker):
  #   docker compose --profile ollama run --rm agent-ollama
  #
  # Usage (Ollama on a remote machine — set OLLAMA_HOST in .env):
  #   docker compose --profile ollama run --rm agent-ollama
