Instructions

Implementation Reference

• src/index.ts:827-856 (handler)

  The handler function extracts parameters, checks credentials, creates FC client, builds and sends ListFunctionVersionsRequest to list function versions, returns success or error response.

  async (args) => {
      const { functionName, region, nextToken, direction, limit } = 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);
      const listFunctionVersionsRequest = new ListFunctionVersionsRequest({
          functionName,
          direction,
      })
      if (nextToken) {
          listFunctionVersionsRequest.nextToken = nextToken;
      }
      if (limit) {
          listFunctionVersionsRequest.limit = limit;
      }
      try {
          const listFunctionVersionsResult = await fcClient.listFunctionVersions(functionName, listFunctionVersionsRequest);
          return { content: [{ type: "text", text: `获取函数版本列表成功。result: ${JSON.stringify(listFunctionVersionsResult)}` }] };
      } catch (error) {
          return { isError: true, content: [{ type: "text", text: `获取函数版本列表失败：${JSON.stringify(error as any)}` }] };
      }
  
  }

• src/index.ts:817-857 (registration)

  Registers the 'list-function-versions' MCP tool with name, description, input schema, and handler function.

  server.tool(
      "list-function-versions",
      "获取函数计算的函数版本列表",

          nextToken: listFunctionVersionsNextTokenSchema.optional(),
          direction: listFunctionVersionsDirectionSchema,
          limit: listFunctionVersionsLimitSchema.optional(),
      },
      async (args) => {
          const { functionName, region, nextToken, direction, limit } = 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` }] };
          }

              listFunctionVersionsRequest.limit = limit;
          }
          try {

• src/schema.ts:172-182 (schema)

  Zod schema definitions for pagination and filtering parameters specific to list-function-versions tool: nextToken, limit, direction.

  export const listFunctionsPrefixSchema = z.string().describe("函数名称前缀，用于过滤函数列表");
  
  export const listFunctionsNextTokenSchema = z.string().describe("函数列表的下一页token，用于分页查询函数列表。第一页不需要提供");
  
  export const listFunctionVersionsNextTokenSchema = z.string().describe("函数版本列表的下一页token，用于分页查询函数版本列表。第一页不需要提供");
  
  export const listFunctionVersionsLimitSchema = z.number().describe("函数版本列表的返回数量上限，默认50，最大100").min(1).max(100).default(50);
  
  export const listFunctionVersionsDirectionSchema = z.enum(["BACKWARD", "FORWARD"]).describe("函数版本列表的排序方向，BACKWARD表示按版本号降序，FORWARD表示按版本号升序").default("BACKWARD");
  
  export const versionIdSchema = z.string().describe("函数版本ID");

• src/index.ts:820-826 (schema)

  Input schema object composing imported Zod schemas for tool parameters.

  {
      functionName: functionNameSchema,
