Implementation Reference

• server.js:2153-2161 (handler)

  Handler for the helm-uninstall tool. Parses arguments for release name and optional namespace, constructs and executes the 'helm uninstall' command via execAsync, and returns the command output or a success message.

  case "helm-uninstall": {
    const { name, namespace } = args;
    const nsArg = namespace ? `-n ${namespace}` : "";
    const cmd = `helm uninstall ${name} ${nsArg}`;
    const { stdout } = await execAsync(cmd);
    return {
      content: [{ type: "text", text: stdout || `Helm release ${name} uninstalled` }]
    };
  }

• server.js:1235-1251 (registration)

  Tool registration entry in the tools array, including name, description, and inputSchema for validation. This is returned by the ListToolsRequestHandler.

    name: "helm-uninstall",
    description: "Uninstall a Helm release",
    inputSchema: {
      type: "object",
      properties: {
        name: { 
          type: "string",
          description: "The name of the release"
        },
        namespace: { 
          type: "string",
          description: "The namespace of the release (optional, defaults to current context namespace)"
        }
      },
      required: ["name"]
    }
  },

• server.js:1237-1249 (schema)

  Input schema defining the expected arguments: required 'name' (string) and optional 'namespace' (string). Used for tool call validation.

  inputSchema: {
    type: "object",
    properties: {
      name: { 
        type: "string",
        description: "The name of the release"
      },
      namespace: { 
        type: "string",
        description: "The namespace of the release (optional, defaults to current context namespace)"
      }
    },
    required: ["name"]
