What the data for this category looks like
Data for consumer building materials intelligent due diligence reports comes primarily from factory inspection documents of manufacturers, building material product databases filed with housing and urban-rural development authorities, and public inspection records from third-party testing institutions. Data update cycles vary by source: factory batch reports update synchronously with production batches, filed information receives bulk updates monthly, and inspection results are published quarterly. Document structures include fixed fields such as product name, specification model, implementation standard number, physical performance parameters, production batch number, full manufacturer name, and inspection date. Units for physical performance parameters include megapascals, millimeters, kilograms per cubic meter, and similar units. No percentage-based labeled items are included.
What constraints do these characteristics impose on the "tool calling and plugins" link
Data sources for consumer building materials are scattered and have significant format differences. This means tool calling must adapt to multiple document formats such as PDF structured tables and JSON structured fields. Precise extraction rules must be configured for building material-specific fields. Data update cycles vary across sources. Factory batch reports require real-time pulling. Filed information requires scheduled synchronization tasks. Tools must distinguish call frequency thresholds for the two types of data. The page count of individual due diligence reports varies widely. Tools must support long text chunking and field-level precise extraction. Physical performance parameter units are inconsistent. Tools must include built-in unit conversion logic to unify output formats.
How to set the configurations
| Configuration Item | Recommended Value | Basis for This Value |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 20 MB | Consumer building materials due diligence reports are mostly multi-page structured documents. Individual files usually do not exceed 20 MB, and this matches the upload limits of most public testing interfaces |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Long text parsing requires multi-field extraction and unit conversion. 300 seconds covers the complete processing flow for most individual reports |
TOOL_CALL_TIMEOUT | 120 seconds | Cross-source data pulling requires connecting to multiple interfaces such as manufacturer and filing databases. 120 seconds covers the total time required for multiple interface calls |
MCP_TOOL_RETRY_TIMES | 2 times | The probability of temporary fluctuations in third-party testing interfaces is low. 2 retries can reduce call failure rates without increasing total time consumption |
FILE_PARSE_CHUNK_SIZE | 800–1200 characters | Building material parameter fields are mostly short text. This chunk length balances parsing accuracy and processing efficiency |
UPLOAD_FILE_ALLOWED_EXTENSIONS | ["pdf", "xlsx", "docx"] | The mainstream submission formats for consumer building materials due diligence reports are these three file types |
The parameter values provided on this page are all conventional recommendations used as starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Phenomenon: MCP tool calls return a
Tool Execution Failederror with no valid return content. Cause: TheMCP_TOOL_RETRY_TIMESparameter is not configured. No retry mechanism is set for temporary fluctuations in third-party testing interfaces. The process is terminated directly after a single call failure. - Phenomenon: When calling the local MinerU tool, uploading a consumer building materials due diligence report is blocked, with a prompt that the file size exceeds the limit. Cause: The
UPLOAD_FILE_MAX_SIZEconfiguration is not adjusted when starting the container. The default limit is 2 MB, which cannot adapt to the actual size of most consumer building materials reports. - Phenomenon: The upload file tool in a custom workflow only supports passing fixed file links and cannot bind global variable parameters. Cause: The variable reference switch for tool parameters is not enabled. Dynamically generated file paths cannot be parsed and passed correctly.
How to confirm that the configuration is correct
- Upload a consumer building materials due diligence report of conventional size. Check whether the upload progress is normal, with no size limit error, to confirm that the configuration takes effect.
- Trigger an MCP tool call. Check whether the log contains retry records to confirm that the parameter configuration is correct.
- Configure the upload file tool in a custom workflow. Try to bind global variable parameters to verify that the parameters can be parsed and passed correctly.
- Call the API interface, modify the timeout-related parameters, and send a test request to confirm that the interface timeout configuration can be adjusted as needed.
