Implementation Reference

• tools/npmInstallTool.ts:16-39 (handler)

  The static method implementing the core logic of the npmInstall tool, executing 'npm install' in the specified directory with optional flags using promisified child_process.exec.

  static async executeInstall(path: string = '.', options: string = ''): Promise<{ stdout: string; stderr: string }> {
    try {
      console.log(`正在執行 npm install ${options} 在路徑 ${path}`);
      
      // 構建完整指令
      const command = `cd ${path} && npm install ${options}`;
      
      // 執行指令
      const { stdout, stderr } = await execPromise(command);
      
      if (stdout) {
        console.log('Install輸出:', stdout);
      }
      
      if (stderr && !stderr.includes('npm notice')) {
        console.error('Install錯誤:', stderr);
      }
      
      return { stdout, stderr };
    } catch (error) {
      console.error('Install執行失敗:', error);
      throw error;
    }
  }

• main.ts:51-66 (registration)

  Registers the 'npmInstall' tool with the MCP server, including input schema definition using Zod and the async handler that calls NpmInstallTool.executeInstall.

  server.tool("npmInstall",
      "執行npm install命令安裝依賴",
      { path: z.string().optional(), options: z.string().optional() },
      async ({ path = ".", options = "" }) => {
          try {
              const result = await NpmInstallTool.executeInstall(path, options);
              return {
                  content: [{ type: "text", text: `Dependencies installed successfully: ${result.stdout}` }]
              };
          } catch (error) {
              return {
                  content: [{ type: "text", text: `Installation failed: ${error instanceof Error ? error.message : "Unknown error"}` }]
              };
          }
      }
  );

• main.ts:53-53 (schema)

  Zod schema defining the input parameters for the npmInstall tool: optional path (defaults to '.') and options.

  { path: z.string().optional(), options: z.string().optional() },
