What Data for This Category Looks Like
Special steel data primarily comes from ERP systems of manufacturing enterprises, spot trading platforms, and publicly available industry association documents. It is mostly used in marketing content created by financial institutions when providing supply chain finance and wealth management services to special steel enterprises.
Data update cadences vary by type. Spot price and inventory data updates daily. Industry statistics and material parameter documents update monthly.
Most documents are structured tables, with fields including grade, chemical composition, mechanical properties, specification dimensions, unit price, inventory quantity, delivery lead time, and others. Units include MPa, mm, yuan/ton, and additional units as needed. Custom order-related documents additionally include custom parameters such as hardenability and hardness. Most such documents are Excel or PDF parameter sheets.
Constraints Imposed on Tool Calls and Plugins by These Characteristics
Marketing content for financial scenarios must be generated quickly. The multi-field and customizable nature of special steel data requires tool calls to support dynamic input of dedicated parameters such as grade and specification, to avoid invalid calls.
Differences in update frequencies across data types require plugins to support different polling interval settings, to ensure the timeliness of data used in marketing content.
Document formats that prioritize structured tables require plugins to support specifying worksheet parsing, to accurately extract target fields.
The presence of custom parameters requires tool calls to support input and return of non-standardized fields, to adapt to the marketing content needs of different clients.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
tool_call_timeout | 30–60 seconds | Special steel spot data has a high update frequency. An overly long timeout will cause request backlogs and harm the real-time performance of marketing content |
custom_tool_schema | Bind grade, specification, and mechanical properties as required fields | Special steel has strong customization demands. Clarifying required parameters can filter invalid calls and ensure returned data matches marketing scenarios |
plugin_request_retry_times | 2 retries | Spot trading platform interfaces occasionally experience fluctuations. Retries reduce call failure rates and prevent interruptions to marketing content generation |
parse_excel_sheet_name | "Material Certificate", "Quotation" | Special steel enterprises commonly use Excel documents with fixed worksheets. Specifying a target for parsing avoids extracting irrelevant data |
required_tool_params | Include "delivery lead time", "inventory quantity" | Marketing content typically requires delivery and inventory information. Mandatory parameters ensure returned data is complete |
unit_conversion_enabled | Enabled | Special steel parameters involve multiple unit formats. Unified conversion adapts to the display requirements of marketing content across different channels |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis. Testing on independent samples is recommended before finalizing settings.
Three Common Mistakes
- A tool call returns the error
The tool call is not supported. This occurs because tool call permissions have not been enabled in the FastGPT backend, or the corresponding plugin has not been added to the available whitelist. - Deployment fails when connecting to MCP services, with a 500 status code returned by the interface. This occurs because custom parameter fields exclusive to special steel have not been added to the MCP schema definition, leading to failed parameter verification.
- Tool call failures occur when generating marketing content using local m3e models after version 4.8.19. This occurs because the new version adjusted the default values of tool call context parameters, and the
maxContextparameter was not updated to adapt to the parsing needs of special steel long documents.
How to Confirm Configuration Is Complete
- Navigate to the tool management page in FastGPT, and check whether the parameters of the configured special steel-related plugins fully match the preset configuration.
- Initiate a tool call request, input standard parameters for the special steel grade "40Cr", and verify whether the returned result includes all preset required fields.
- Simulate a marketing content generation scenario, trigger a tool call, and check whether the units of the returned data are uniformly converted to the target format.
- View the plugin call logs, confirm that the retry times and timeout period meet the configuration requirements, and that there are no abnormal error records.
