notes: Lightbend (dba Akka) ships a first-party MCP server as a subcommand of the Akka CLI. `akka mcp
  serve` exposes Akka CLI operations as MCP tools over stdio for IDE / desktop MCP clients. It is marked
  "[Incubating]" in the CLI reference. Separately, the Akka SDK lets developers author their own MCP endpoints
  in their services (`@McpEndpoint`), served over stateless Streamable HTTP at `/mcp`.
