What Data for This Category Looks Like
Minor metals financial report data is sourced from public disclosures by domestic minor metals industry associations, regular reports of corresponding listed companies, and public quotes from professional spot trading platforms. Two update schedules apply to this data: listed company financial reports are updated on a fixed quarterly and annual basis, while industry spot and supply and demand data is updated daily. Document structures include fields for core categories such as output, inventory, import and export volume, average grade, and spot price. Most units are tons, yuan per ton, and grade percentage. Some individual sub-categories require marking oxide conversion content.
Constraints for Tool Calling and Plugins
The mixed update schedules of minor metals financial reports and spot data require tool calling to use separate interface adaptations for quarterly financial report batch retrieval and real-time spot data retrieval. Differences in units and conversion rules across categories require plugins to include field unit mapping logic, to avoid mismatches between numerical values and units. Specialized fields for individual sub-categories (such as tungsten ore WO3 grade) require tool calling to support precise field filtering, to avoid returning redundant data. The large scale of batch retrieval for financial report data requires adaptation to longer timeout thresholds and pagination retrieval logic.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
tool_call_timeout | 300–600 seconds | Adapts to the long-duration requirements of minor metals financial report batch retrieval, preventing single tool call timeouts and interruptions |
plugin_field_mapping | Preset mapping rules per category | Matches unique units and conversion fields for minor metals, such as mapping WO3 grade to standard output fields |
data_pull_batch_size | 50–100 items per request | Balances retrieval efficiency and interface load, adapting to batch query scenarios for financial report data |
unit_conversion_enabled | Enabled | Uniformly processes multi-unit data such as yuan per ton and USD per ton, preventing mixed result units |
MCP_DEPLOY_PORT | 8080–8090 | Reserves a commonly used port range to avoid conflicts with local service ports |
tool_call_retry_count | 2 retries | Addresses occasional fluctuations in minor metals data interfaces, reducing call failure rates |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, 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 Misconfiguration Issues
- Configuring a MySQL tool call results in a 400 status code returned in conversations (no body). This occurs because field filtering rules for minor metals financial report data are not correctly configured, leading to invalid sub-category fields included in request parameters and triggering interface verification failures.
- Calling a custom code plugin to retrieve minor metals spot data results in an AggregateError Code: ETIMEDOUT prompt. This occurs because the
tool_call_timeoutparameter is not adjusted, and the real-time retrieval duration of minor metals spot data exceeds the default threshold, causing connection timeouts. - Disabling unit conversion configuration results in mixed units appearing in generated financial report analysis results. This occurs because
plugin_field_mappingrules are not configured, and unique oxide conversion units and price units for minor metals are not uniformly processed.
How to Verify Successful Configuration
- Initiate a single tool call for financial report data of a minor metals category, and check whether returned fields and units match preset mapping rules.
- Test batch retrieval of financial report data, confirm that call duration does not exceed the configured
tool_call_timeoutthreshold, and no timeout errors occur. - View MCP deployment logs, confirm that the service is listening normally on the specified port, and no port conflict errors are present.
- Trigger a custom code plugin call, check whether minor metals spot data can be retrieved correctly, and no connection timeout prompts appear.
