Tool Calling and Plugins for Plastics and Rubber Financial

What Data for This Category Looks Like

Plastics and rubber category financial report data comes from three main sources: publicly disclosed periodic reports and temporary announcements of listed companies, plus monthly operating data released by industry associations. Update schedules follow fixed timelines:

Quarterly reports are released within one month after the end of each quarter
Annual reports are released from March to April of the following year
Temporary announcements are issued for sudden business changes

Most documents are in PDF format. They include segment revenue, production capacity and output, cost structure, import and export data, and other content. Core fields include current period output, sales volume, unit cost, and revenue amount. Common units are tons, yuan per ton, and ten thousand yuan. Some files include accompanying illustrations such as production capacity bar charts and price trend line charts.

Constraints for Tool Calling and Plugins

The characteristics of plastics and rubber financial report data create multiple constraints for tool calling and plugin workflows:

Data sources are scattered. Tools must connect to exchange public announcements, industry association databases, and commodity price data sources simultaneously. This increases the complexity of multi-plugin linkage.
Document sizes are large and include multiple accompanying images. Tools must support large file parsing and batch parameter passing for multiple images.
Field units are mixed. For example, output uses both tons and thousand tons. Tools must complete standardized unit conversion.
Analysis requires linking to commodity price fluctuation data. Tools must call external price query plugins in real time. This places higher requirements on plugin response latency.

Configuration Settings

Configuration Item	Recommended Setting	Rationale
`PARSE_FILE_MAX_SIZE`	`200 MB`	Plastics and rubber sector financial report PDFs often contain extensive supplementary tables and images. 200 MB covers the size requirements of most disclosed documents
`UPLOAD_IMAGE_BATCH_SIZE`	`10 images per batch`	Financial reports include 10 or fewer charts for production capacity and prices. A 10-image batch size adapts to common disclosure formats
`PLUGIN_REQUEST_TIMEOUT`	`120 seconds`	Commodity price plugins pull multi-dimensional raw material price data. 120 seconds accommodates cross-data source query delays
`MCP_TRIGGER_MODE`	`Trigger after file parsing completes`	Financial report data requires structured parsing before valid fields can be extracted. MCP triggers must wait for parsing to finish before passing parameters
`PLUGIN_PARAM_VALIDATION`	`Enable field format validation`	Financial reports use mixed units such as tons and thousand tons. Validation prevents call failures caused by mismatched parameter formats
`CONTEXT_WINDOW_SIZE`	`8000–12000 characters`	Plastics and rubber sector financial report analysis requires linking multiple sections of business descriptions and data tables. This window retains sufficient context for cross-paragraph correlation

The parameter values listed on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require targeted analysis. It is recommended to test on your own samples before finalizing settings.

Three Common Misconfigurations

Scenario: MCP function calls return empty fields or parameter format mismatch errors. Cause: No unit standardization validation is applied to parsed financial report fields. Plastics and rubber financial reports often mix tons and thousand tons units. Unstandardized parameters cannot be recognized by plugins.
Scenario: Plugin calls return 403 Forbidden error codes after deployment. This applies to plugin system updates for version 4.10.0. Cause: No publicly accessible storage service is configured. Plastics and rubber financial report images require transit through a storage service. Intranet storage cannot be pulled by plugins.
Scenario: Generated analysis reports or PPTs lack commodity price comparison content. Cause: No dedicated plugin linked to commodity data sources is configured. Plastics and rubber financial report analysis requires linking to raw material price fluctuation data. Missing corresponding plugin calls prevent generation of comparison content.

How to Verify Successful Configuration

Upload a financial report PDF from a listed plastics or rubber company. Check that parsed fields include core business data to confirm expected field extraction.
Configure a commodity price plugin. Pass the parsed raw material name to verify that the plugin returns price data for the corresponding period. Confirm that linkage logic works correctly.
Trigger the MCP function. Pass parsed structured fields to check that plugins correctly receive and process parameters with no missing fields or format errors.
View storage service access logs. Confirm that plugins can normally pull images from financial reports with no access permission errors.
