Implementation Reference

• vmware_avi/ops/ako_config.py:12-25 (handler)

  Core handler: runs 'helm get values ako -n avi-system -o yaml' to fetch current AKO Helm values.yaml configuration.

  def show_ako_config(namespace: str = "avi-system") -> None:
      """Show current AKO Helm values."""
      result = subprocess.run(
          ["helm", "get", "values", "ako", "-n", namespace, "-o", "yaml"],
          capture_output=True,
          text=True,
          timeout=120,
      )
      if result.returncode != 0:
          console.print(f"[red]Failed to get AKO values: {result.stderr.strip()}[/red]")
          raise SystemExit(1)
  
      console.print("\n[bold]AKO Helm Values[/bold]\n")
      console.print(result.stdout)

• mcp_server/server.py:327-330 (handler)

  MCP tool def: ako_config_show() decorated with @mcp.tool and @vmware_tool, imports show_ako_config and captures its output.

  def ako_config_show() -> str:
      """[READ] Show current AKO Helm values.yaml configuration — controller IP, cloud name, network settings, and feature flags."""
      from vmware_avi.ops.ako_config import show_ako_config

• mcp_server/server.py:325-330 (registration)

  Registration: decorated with @mcp.tool and @vmware_tool(risk_level='low') registering the tool named 'ako_config_show' with FastMCP.

  @mcp.tool(annotations={"readOnlyHint": True, "destructiveHint": False, "idempotentHint": True, "openWorldHint": True})
  @vmware_tool(risk_level="low")

• mcp_server/server.py:327-330 (schema)

  Schema: annotations={'readOnlyHint': True, 'destructiveHint': False, 'idempotentHint': True, 'openWorldHint': True} — read-only, no params, returns str.
