publish-function-version

Instructions

Implementation Reference

• src/index.ts:793-814 (handler)

  The handler function that implements the core logic for publishing a new version of the function using the Alibaba Cloud Function Compute SDK. It validates credentials, fetches account ID, creates FC client, and invokes publishFunctionVersion.

          const { functionName, region, description } = args;
          const accessKeyId = process.env.ALIBABA_CLOUD_ACCESS_KEY_ID;
          const accessKeySecret = process.env.ALIBABA_CLOUD_ACCESS_KEY_SECRET;
          if (!accessKeyId || !accessKeySecret) {
              return { isError: true, content: [{ type: "text", text: `执行失败，请设置ALIBABA_CLOUD_ACCESS_KEY_ID, ALIBABA_CLOUD_ACCESS_KEY_SECRET, ALIBABA_CLOUD_SECURITY_TOKEN环境变量` }] };
          }
          const accountId = await getAccountId();
          if (!accountId) {
              return { isError: true, content: [{ type: "text", text: `执行失败，获取accountId异常` }] };
          }
          const fcClient = createFcClient(region);
          try {
              const request = new PublishFunctionVersionRequest({
                  description,
              })
              const result = await fcClient.publishFunctionVersion(functionName, request);
              return { content: [{ type: "text", text: `发布函数版本成功。result: ${JSON.stringify(result)}` }] };
          } catch (error) {
              return { isError: true, content: [{ type: "text", text: `发布函数版本失败：${JSON.stringify(error as any)}` }] };
          }
      }
  )

• src/schema.ts:4-6 (schema)

  Zod schema definition for the 'region' parameter used in the tool.

  export const regionSchema = z.enum(['cn-hangzhou', 'cn-shanghai', 'cn-beijing', 'cn-shenzhen', 'cn-hongkong', 'ap-southeast-1', 'ap-southeast-2', 'ap-southeast-3', 'ap-southeast-5', 'ap-northeast-1', 'eu-central-1', 'eu-west-1', 'us-west-1', 'us-east-1', 'ap-south-1', 'me-east-1', 'cn-chengdu', 'cn-wulanchabu', 'cn-guangzhou'])
      .default('cn-hangzhou')
      .describe("部署的区域，当前可选的区域是cn-hangzhou, cn-shanghai, cn-beijing, cn-shenzhen, cn-hongkong, ap-southeast-1, ap-southeast-2, ap-southeast-3, ap-southeast-5, ap-northeast-1, eu-central-1, eu-west-1, us-west-1, us-east-1, ap-south-1, me-east-1, cn-chengdu, cn-wulanchabu, cn-guangzhou，默认是cn-hangzhou");

• src/schema.ts:119-120 (schema)

  Zod schema definition for the 'functionName' parameter used in the tool.

  export const functionNameSchema = z.string().describe("函数名称，函数名称在每个region必须是唯一的。")
      .regex(/^[a-zA-Z0-9_][a-zA-Z0-9_-]{0,63}$/);

• src/schema.ts:137-137 (schema)

  Zod schema definition for the 'description' parameter used in the tool.

  export const functionVersionDescriptionSchema = z.string().describe("函数版本的描述，可以描述一下发布的函数版本的功能。");

• src/index.ts:785-814 (registration)

  MCP server tool registration for 'publish-function-version', specifying name, description, input schema, and inline handler function.

      "publish-function-version",
      "将函数的最新代码发布为新版本",
      {
          functionName: functionNameSchema,
          region: regionSchema,
          description: functionVersionDescriptionSchema,
      },
      async (args) => {
          const { functionName, region, description } = args;
          const accessKeyId = process.env.ALIBABA_CLOUD_ACCESS_KEY_ID;
          const accessKeySecret = process.env.ALIBABA_CLOUD_ACCESS_KEY_SECRET;
          if (!accessKeyId || !accessKeySecret) {
              return { isError: true, content: [{ type: "text", text: `执行失败，请设置ALIBABA_CLOUD_ACCESS_KEY_ID, ALIBABA_CLOUD_ACCESS_KEY_SECRET, ALIBABA_CLOUD_SECURITY_TOKEN环境变量` }] };
          }
          const accountId = await getAccountId();
          if (!accountId) {
              return { isError: true, content: [{ type: "text", text: `执行失败，获取accountId异常` }] };
          }
          const fcClient = createFcClient(region);
          try {
              const request = new PublishFunctionVersionRequest({
                  description,
              })

  )

• src/utils/alibaba_cloud_sdk.ts:11-17 (helper)

  Helper function to create the Alibaba Cloud Function Compute (FC) client instance used in the handler.

  export function createFcClient(regionId: string) {
    const config = new $OpenApi.Config({
      credential: getCredentialClient(),
      endpoint: `fcv3.${regionId}.aliyuncs.com`,
    });
    return new FCClient(config);
  }
