What the data for this category looks like
Data related to shipping port financial reports comes from public periodic reports disclosed by port operating entities, and monthly operational data released by industry statistical institutions. Update schedules follow these rules:
- Annual full financial reports are released 1 to 3 months after the end of each fiscal year
- Quarterly operational data is released 1 month after the end of each quarter
- Monthly throughput data is released 10 days after the end of the current month
Document structures include modules such as core operational indicators, cost structure, revenue composition, and balance sheet details. Fields include container throughput, bulk cargo throughput, route schedules, berth operating hours, revenue amount, and more. Units are TEU, 10,000 tons, schedules, hours, and CNY respectively.
Constraints imposed on tool calling and plugins
Public financial reports have layered update cycles. Annual financial reports have large file sizes, while monthly operational data is updated frequently. Tool calling must support switching data source retrieval logic based on time granularity. The multi-module document structure requires plugins to include built-in chunk parsing rules to accurately extract specified fields. Significant differences in field units require plugins to include built-in unit standardization mapping logic to avoid unit confusion across data sources. Disclosure formats vary across different ports. Tool calling must adapt to parsing templates for multiple public documents to reduce field extraction bias.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Shipping port financial reports have large single-file sizes and include multi-module details, resulting in long parsing times. 600 seconds covers the complete parsing process. |
maxContext | 8000–12000 characters | After chunking financial report documents, complete business logic must be retained. This range covers the core content of a single module and avoids context truncation. |
Recall count | Top 8–10 entries | Financial report fields cover multiple dimensions. A sufficient number of associated fragments must be recalled to support complete analysis and avoid missing key information. |
Similarity threshold | 0.75–0.85 | Precise matching between financial report fields and analysis requirements is needed. This range filters low-relevance fragments while retaining field variants within the same category. |
UPLOAD_FILE_MAX_SIZE | 500 MB | Annual financial reports include attachments such as detailed balance sheets and cash flow statements. This upper limit covers most fully disclosed public financial report files. |
Tool call retry count | 2 times | Some third-party industry data interfaces experience temporary fluctuations. Limited retries improve call success rates and avoid excessive waiting. |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume and business rules. Specific issues require targeted analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Phenomenon: Timeouts occur when calling the knowledge base to generate financial report analysis, with duration exceeding 10 seconds. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted, and the default timeout duration is insufficient to cover the parsing process for large financial report files. - Phenomenon: In analysis results returned by API calls, the content of the subsequent variable overlaps with the result of the previous variable. Cause: The
maxContextparameter is not configured correctly, resulting in residual context from the previous call output that causes variable concatenation exceptions. - Phenomenon: When calling MCP tools to pull port operational data, a connection failure error is returned. Cause: Correct data source API access permissions are not configured, or the tool call timeout setting is shorter than the response duration of the port data interface.
How to confirm configurations are set correctly
- Upload a sample single port financial report file, and verify that the extracted fields and units after parsing match the preset rules.
- Initiate a single tool call test, and adjust
PARSE_FILE_TIMEOUT_SECONDSto a value suitable for the scenario based on response duration. - Call the API to initiate an analysis request, and check that each variable in the returned analysis result is independent with no concatenated residual content.
- Verify the connection status of the MCP tool, and confirm that the data source access permissions and configuration parameters match business requirements.
