What the data for this category looks like
Core data sources for chemical raw materials include public chemical industry databases, supplier self-operated quotation systems, and supply and demand briefings released by industry associations. Basic parameters such as CAS registry numbers, product specifications, and packaging forms are updated on a long-term stable basis; quotation data is synchronized daily, and supply and demand trend data is updated monthly. A single structured data entry contains more than ten fields, including product identifier, purity index, packaging unit, current quotation range, supplier location, delivery lead time, etc. The length of a single unstructured product description text varies widely.
How These Data Characteristics Constrain Tool Calling and Plugins
The data characteristics of chemical raw materials impose clear constraints on tool calling and plugins: Quotation data is updated daily, requiring tool calling configurations to use a short-cycle cache invalidation mechanism to avoid returning outdated marketing materials; fields include clear units and exclusive identifiers such as CAS registry numbers, so plugins must strictly verify that parameter formats match units to prevent parameter mismatches during calls; additionally, there are both structured and unstructured data types, so the calling logic for the two data types must be differentiated, with CAS numbers as the priority key for structured retrieval to improve calling accuracy. Marketing content must match real-time market trends, and tool triggers must be tied to the real-time needs of user queries, and long-term static caching should not be used.
How to Configure the Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
tool_call_cache_ttl | 300 seconds | Matches the daily update frequency of chemical raw material quotations to avoid returning outdated marketing materials |
tool_call_param_schema | Configure validation rules for CAS registry numbers, packaging units, and purity indicators | Chemical raw material fields include exclusive identifiers and clear units, so parameter format validation must be strictly enforced |
max_tool_call_rounds | 3 times | Limits the number of cycles for complex parameter validation to avoid invalid calls consuming resources |
mcp_custom_headers | Configure custom request headers according to the requirements of the target interface | Adapts to the authentication requirements of most chemical supplier interfaces |
tool_response_parse_mode | Structured-first parsing | Most chemical raw material data consists of structured fields, so prioritizing structured results improves content accuracy |
tool_trigger_threshold | Calibrated based on actual testing | Adapts to tool calling confidence requirements across different scenarios to avoid invalid requests |
The parameter values provided on this page are all common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Tool calls return a 400 status code (no body), the interface displays tool call failure, and no response body content is present in logs. The cause is that MCP custom request headers are not configured correctly, leading to authentication failure and the interface returning an empty response body.
- Model function calls perform poorly, and the generated marketing content does not match exclusive fields of chemical raw materials such as CAS registry numbers. The cause is that tool calling parameter validation rules are not configured, so the model cannot accurately identify exclusive identifiers, leading to call results that do not meet requirements.
- Calling the Mermaid MCP Server to generate flow charts fails, and image links cannot be obtained in the workflow. The cause is that the tool response parsing mode is not configured as structured-first parsing, leading to failure to correctly extract the image address field generated by Mermaid.
How to Confirm the Configuration Is Complete
- Initiate a tool call request that includes a CAS registry number, and check whether the returned results include the latest product parameters and quotation information.
- View tool call logs to confirm that authentication information is correctly carried in the request headers, and there are no 400-level empty response body errors.
- Test parameter inputs in different formats to verify that the parameter validation rules block requests that do not meet requirements.
- Generate marketing content to confirm that the content includes exclusive fields of chemical raw materials and real-time data.
