What the Data for This Category Looks Like
Data sources cover multiple channels including industrial and commercial public disclosure systems, credit reporting service institutions, industry supervision databases, partner business ledgers, and others. Data update cycles vary: industrial and commercial entity information is updated monthly, credit reports are updated in real time or T+1, and industry supervision data is updated quarterly. The document structure includes structured fields and unstructured attachments. Structured fields include entity name, unified social credit identifier, administrative penalty records, related transaction details, and others. Amount fields use ten thousand yuan as the unit, date fields use the YYYY-MM-DD format, and unstructured attachments are mostly scanned reports or original voucher files.
What Constraints These Characteristics Impose on the "Tool Calling and Plugins" Workflow
Multi-data-source access requires plugins to support multiple calling protocols such as REST API, direct database connection, and file parsing. Plugins must be compatible with different authentication methods including API Key, OAuth, and enterprise intranet certificates. Data sources with different update cycles need differentiated scheduled synchronization parameters. This prevents high-frequency calls from triggering interface rate limits, or low-frequency calls from causing insufficient data timeliness. There are many structured fields with high standardization requirements. Tool calling must strictly verify the completeness and format compliance of input parameters. This stops non-standardized data from disrupting due diligence report generation logic. Unstructured attachment parsing must adapt to multiple file formats. Plugins must support streaming processing of large-volume attachments.
How to Set Configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
UPLOAD_FILE_ALLOWED_EXTENSIONS | csv,json,xlsx,pdf,docx,zip | Covers commonly used structured data, attachment, and compressed package formats for comprehensive service due diligence reports. Supports default full selection to adapt to MCP docking requirements. |
MCP_PLUGIN_AUTH_STORAGE | Unified Encrypted Hosting | Centralizes management of authentication keys for multiple third-party data sources and models. Avoids security risks from decentralized storage. Adapts to the MCP function of FastGPT 4.9.6 and above versions. |
MCP_REQUEST_TIMEOUT | 300 seconds | Adapts to long-duration scenarios of pulling aggregated interfaces for comprehensive service due diligence. Avoids interrupting the data acquisition process due to timeout. |
PLUGIN_PARAM_VALIDATION_STRICTNESS | Strict Mode | Matches the high standardization requirements of due diligence report fields. Verifies the completeness and format compliance of input parameters. Reduces invalid calls. |
MODEL_API_KEY_ENCRYPTION | Enabled | Encrypts and stores authentication keys for third-party models such as OneAPI. Resolves the issue of key loss caused by plaintext input. |
PLUGIN_RETRY_TIMES | 2 times | Addresses temporary fluctuations in due diligence data interfaces. Limited retries reduce the impact of single call failures. |
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 specific analysis, and it is recommended to test on your own samples before finalizing.
Three Common Mistakes
- Symptom: A null pointer error occurs after configuring the OneAPI model key and calling the API. Cause: The
MODEL_API_KEY_ENCRYPTIONconfiguration is not enabled. The key is directly entered in plaintext, causing the system to fail to load correctly or the key to be truncated. - Symptom: Missing fields are returned when calling third-party data sources via MCP. Cause:
PLUGIN_PARAM_VALIDATION_STRICTNESSis not configured to Strict Mode. Non-standardized fields are incorrectly filtered, which does not meet the field requirements of due diligence reports. - Symptom: Uploaded due diligence report attachments cannot be parsed by plugins. Cause: The corresponding file format is not added to
UPLOAD_FILE_ALLOWED_EXTENSIONS. The system defaults to intercepting required attachment types.
How to Confirm the Configuration is Correct
- Enter the plugin management page. Check the
UPLOAD_FILE_ALLOWED_EXTENSIONSconfiguration item. Upload test files of the corresponding format. Confirm that files can be uploaded normally. - Call the MCP interface to pull a single due diligence data entry. View the authentication status and returned fields in the call log. Confirm that there are no null value errors or format mismatch issues.
- Switch the authentication storage method of the OneAPI model. Initiate a model call. Confirm that there are no key-related null errors.
- Simulate batch pulling of due diligence data. Observe the timeout and retry records in the plugin call log. Confirm that the configured timeout time and retry times meet business expectations.
