What the data for this category looks like
Financial report data for listed companies in the coal chemical industry comes primarily from periodic reports disclosed by domestic and overseas stock exchanges, and monthly operation monitoring data released by industry self-regulatory organizations. Update timelines follow regulatory requirements: annual reports are disclosed once per year, quarterly reports are updated within one month after the end of each quarter, and monthly industry data is released in the first ten days of the following month.
Each individual financial report document includes modules such as production capacity, output, raw material procurement costs, revenue from each coal chemical product, energy consumption indicators, cash flow and liabilities. Common field units are ten thousand tons (for output), 100 million yuan (for revenue), and tons of standard coal per ton of product (for unit energy consumption). Industry monitoring data also includes quantitative values for plant operating rates, with no additional custom units.
Constraints on tool calling and plugins
The long-form documents, multi-source data with varying update frequencies, and large number of detailed fields associated with coal chemical financial reports create multiple constraints for tool calling and plugins. Long documents require tools to support chunked parsing and context stitching to avoid exceeding model context window limits. Multi-source data (exchange financial reports, industry monitoring data) requires plugins to be configured with multi-format parsing rules to adapt to standardized tables and free-form text content. High-frequency monthly updated data requires scheduled trigger parameters for tool calls to support short update cycles, and data version verification logic must be added to prevent calls to outdated information. The large number of detailed product fields requires precise configuration of field mapping rules during tool calls to avoid parameter matching errors.
Configuration settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–16000 characters | The core analysis paragraphs of a single coal chemical financial report are approximately 10,000 to 20,000 words. Chunking this content fits the context window limits of mainstream models |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Long document parsing requires sufficient time for text splitting and structured extraction |
UPLOAD_FILE_MAX_SIZE | 1000 MB | A complete annual report PDF or Excel file typically does not exceed 500 MB, so this value leaves adequate headroom |
tool_call_batch_size | 2–3 | Avoid triggering third-party interface rate limits by sending too many requests simultaneously |
data_version_check_interval | 7 days | Monthly industry data updates occur approximately every 30 days, so this check interval aligns with the update schedule |
field_mapping_template | Pre-configured based on coal chemical financial report standard fields | Coal chemical product and energy consumption fields follow unified regulatory disclosure formats. Pre-configured templates reduce manual configuration errors |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three common misconfigurations
- Phenomenon: A
504 Gateway Timeouterror occurs during tool calling, or the output is interrupted mid-process with no results. Cause: Timeout parameters adapted for long document parsing are not configured, causing the long financial report parsing process to trigger platform timeout limits. - Phenomenon: After sending a termination command to the MCP server, the tool continues executing without stopping. Cause: The MCP command termination callback is not enabled in the plugin configuration, or the termination command parameter format does not meet the MCP server interface requirements.
- Phenomenon: The workflow fails to respond after sending a start command to an external application. Cause: Local execution permissions for the workflow are not configured, or the path parameter of the call command does not point to the correct application installation directory.
How to verify proper configuration
- Upload a sample coal chemical financial report file, check if the structured parsed fields include preset modules such as production capacity and revenue, to confirm the parsing rules are active.
- Initiate a tool call request, check if the workflow logs include data version verification records, to confirm the version check logic is running normally.
- Send a termination command to the configured MCP plugin, check if the server-side tool process stops, to confirm the termination callback configuration is active.
- Adjust the tool call batch request count, observe the interface return status, to confirm the rate limit configuration meets actual call requirements.
