Implementation Reference

• src/espresso_mcp/server.py:33-42 (handler)

  The handler function for the 'list_emulators' tool. It runs 'adb devices' to list running Android emulators, parses the output to extract emulator IDs, and returns them as a list.

  @mcp.tool()
  def list_emulators() -> list:
      """List all running Android Emulators"""
      result = subprocess.run(["adb", "devices"], capture_output=True, text=True)
      if result.returncode != 0:
          raise RuntimeError(f"Error listing emulators: {result.stderr}")
      lines = result.stdout.splitlines()
      print("---lines", lines)
      emulators = [line.split()[0] for line in lines[1:] if "emulator" in line]
      return emulators

• src/espresso_mcp/server.py:33-33 (registration)

  The @mcp.tool() decorator registers the list_emulators function as an MCP tool.

  @mcp.tool()
