Implementation Reference

• src/index.ts:1395-1418 (handler)

  Handler function that runs the `magerun2 sys:website:list` command with optional output format (table, json, csv), handles errors, and returns formatted results.

  async ({ format = "table" }) => {
    const command = `magerun2 sys:website:list --format=${format}`;
    const result = await executeMagerun2Command(command, format === "json");
  
    if (!result.success) {
      return {
        content: [{
          type: "text",
          text: result.error
        }],
        isError: true
      };
    }
  
    const responseText = format === "json"
      ? `Website list (${format} format):\n\n${JSON.stringify(result.data, null, 2)}`
      : `Website list (${format} format):\n\n${result.data}`;
  
    return {
      content: [{
        type: "text",
        text: responseText
      }]
    };

• src/index.ts:1389-1393 (schema)

  Input schema defining the optional 'format' parameter for output formatting.

  inputSchema: {
    format: z.enum(["table", "json", "csv"])
      .default("table")
      .describe("Output format")
  }

• src/index.ts:1384-1420 (registration)

  Full registration of the 'sys-website-list' tool including schema, title, description, and inline handler function.

  server.registerTool(
    "sys-website-list",
    {
      title: "Website List",
      description: "List all Magento 2 websites",
      inputSchema: {
        format: z.enum(["table", "json", "csv"])
          .default("table")
          .describe("Output format")
      }
    },
    async ({ format = "table" }) => {
      const command = `magerun2 sys:website:list --format=${format}`;
      const result = await executeMagerun2Command(command, format === "json");
  
      if (!result.success) {
        return {
          content: [{
            type: "text",
            text: result.error
          }],
          isError: true
        };
      }
  
      const responseText = format === "json"
        ? `Website list (${format} format):\n\n${JSON.stringify(result.data, null, 2)}`
        : `Website list (${format} format):\n\n${result.data}`;
  
      return {
        content: [{
          type: "text",
          text: responseText
        }]
      };
    }
  );

• src/index.ts:28-88 (helper)

  Shared utility function used by sys-website-list (and other tools) to execute magerun2 commands safely with timeout, JSON parsing, and Magento-specific error handling.

  async function executeMagerun2Command(command: string, parseJson: boolean = false): Promise<{
    success: true;
    data: any;
    rawOutput: string;
  } | {
    success: false;
    error: string;
    isError: true;
  }> {
    try {
      const { stdout, stderr } = await execAsync(command, {
        cwd: process.cwd(),
        timeout: 30000 // 30 second timeout
      });
  
      if (stderr && stderr.trim()) {
        console.error("magerun2 stderr:", stderr);
      }
  
      if (parseJson) {
        try {
          return { success: true, data: JSON.parse(stdout), rawOutput: stdout };
        } catch (parseError) {
          return {
            success: false,
            error: `Error parsing magerun2 JSON output: ${parseError}\n\nRaw output:\n${stdout}`,
            isError: true
          };
        }
      }
  
      return { success: true, data: stdout.trim(), rawOutput: stdout };
  
    } catch (error) {
      const errorMessage = error instanceof Error ? error.message : String(error);
  
      // Check if magerun2 is not found
      if (errorMessage.includes("command not found") || errorMessage.includes("not recognized")) {
        return {
          success: false,
          error: "Error: magerun2 command not found. Please ensure n98-magerun2 is installed and available in your PATH.\n\nInstallation instructions: https://github.com/netz98/n98-magerun2",
          isError: true
        };
      }
  
      // Check if not in Magento directory
      if (errorMessage.includes("not a Magento installation") || errorMessage.includes("app/etc/env.php")) {
        return {
          success: false,
          error: "Error: Current directory does not appear to be a Magento 2 installation. Please run this command from your Magento 2 root directory.",
          isError: true
        };
      }
  
      return {
        success: false,
        error: `Error executing magerun2 command: ${errorMessage}`,
        isError: true
      };
    }
  }
