Implementation Reference

• src/index.ts:675-718 (handler)

  Main handler for 'query_sign_flow' tool in the CallToolRequestSchema switch statement. Extracts flowId, calls getSignFlowDetail, formats status and times, and returns formatted details or error.

          case "query_sign_flow": {
              try {
                  const args = request.params.arguments as { flowId: string };
                  const detail = await getSignFlowDetail(args.flowId);
  
                  const statusMap: Record<number, string> = {
                      0: "草稿",
                      1: "签署中",
                      2: "完成",
                      3: "撤销",
                      5: "过期",
                      7: "拒签"
                  };
  
                  const formatTime = (timestamp: number | null) => {
                      if (!timestamp) return "未完成";
                      return new Date(timestamp).toLocaleString();
                  };
  
                  return {
                      content: [{
                          type: "text",
                          text: `签署流程详情：
  状态：${statusMap[detail.signFlowStatus] || "未知"} (${detail.signFlowDescription})
  创建时间：${formatTime(detail.signFlowCreateTime)}
  开始时间：${formatTime(detail.signFlowStartTime)}
  完成时间：${formatTime(detail.signFlowFinishTime)}
  文档：${detail.docs.map(doc => doc.fileName).join(", ")}
  签署人：${detail.signers.map(signer =>
                              signer.psnSigner ?
                                  `${signer.psnSigner.psnName} (${signer.psnSigner.psnAccount.accountMobile})` :
                                  "企业签署"
                          ).join(", ")}`
                      }]
                  };
              } catch (err: any) {
                  return {
                      content: [{
                          type: "text",
                          text: `Error: ${err.message}`
                      }]
                  };
              }
          }

• src/index.ts:189-200 (schema)

  Input schema definition for 'query_sign_flow' tool, requiring 'flowId' string.

  name: "query_sign_flow",
  description: "Query sign flow details",
  inputSchema: {
      type: "object",
      properties: {
          flowId: {
              type: "string",
              description: "Sign flow ID"
          }
      },
      required: ["flowId"]
  }

• src/index.ts:188-201 (registration)

  Tool registration in ListToolsRequestSchema response, defining name, description, and input schema.

  {
      name: "query_sign_flow",
      description: "Query sign flow details",
      inputSchema: {
          type: "object",
          properties: {
              flowId: {
                  type: "string",
                  description: "Sign flow ID"
              }
          },
          required: ["flowId"]
      }
  }

• src/index.ts:572-586 (helper)

  Helper function that queries the eSign API for sign flow details using the provided flowId.

  async function getSignFlowDetail(flowId: string): Promise<SignFlowDetailResponse> {
      const requestPath = `/v3/sign-flow/${flowId}/detail`;
      const headers = getCommonHeaders('GET', requestPath, 'application/json; charset=UTF-8');
  
      const response = await fetch(`${config.host}${requestPath}`, {
          method: 'GET',
          headers: headers
      });
  
      const result = await response.json() as ApiResponse<SignFlowDetailResponse>;
      if (result.code === 0) {
          return result.data;
      }
      throw new Error(`Failed to get sign flow detail: ${result.message}`);
  }

• src/index.ts:93-115 (schema)

  TypeScript interface defining the structure of the sign flow detail response from the API.

  interface SignFlowDetailResponse {
      signFlowStatus: number;
      signFlowDescription: string;
      signFlowCreateTime: number;
      signFlowStartTime: number;
      signFlowFinishTime: number | null;
      docs: Array<{
          fileId: string;
          fileName: string;
      }>;
      signers: Array<{
          psnSigner?: {
              psnName: string;
              psnAccount: {
                  accountMobile: string;
                  accountEmail: string | null;
              };
          };
          signerType: number;
