Tool Calling and Plugins for Automated Equipment Financing

What Data for This Category Looks Like

Data for automated equipment financing daily reports comes from three primary sources: industry association equipment purchase filing databases, bank corporate credit loan systems, and financing lease company transaction ledgers. Data is updated daily. Same-day transaction data is summarized and synced during the early morning of the following day.

Each daily report is grouped by major equipment categories, and includes fixed fields: unique equipment ID, purchasing entity name, financing amount (unit: ten thousand yuan), financing term (unit: month), loan date, equipment model, full manufacturer name, and more. Supplementary entries may include guarantor information and repayment plan summaries.

Constraints for Tool Calling and Plugins

Since data originates from three separate systems, tool calling must support multi-source interface integration and data aggregation. Cross-source authentication and format conversion rules must be configured.

The daily update cadence requires tool calling scheduled tasks to align with this rhythm. Incremental sync logic must also be configured to avoid repeatedly pulling historical data.

Fields with specific units require unit validation during tool calling, to prevent non-standard values from entering downstream processing workflows. Unique equipment ID is the core identifier, and must be used as a key parameter for deduplication and associated queries during tool calling. Failure to do so will result in data confusion.

Additionally, the sensitive nature of financing data requires permission validation to be configured during tool calling, restricting unauthorized interface access.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`tool_request_timeout`	`300 seconds`	Automated equipment financing daily reports have large per-batch data volumes, and interface response times are typically long. This value covers most normal request cycles
`tool_batch_size`	`50 items per request`	Single daily reports have many entries. This batch size balances interface load and processing efficiency
`field_unit_check_enabled`	`Enabled`	Must validate that financing amount is in ten thousand yuan and financing term is in months to prevent dirty data from entering the system
`incremental_sync_interval`	`Daily 00:00`	Matches the daily update rhythm of financing daily reports to ensure same-day data is synced on schedule
`mcp_server_connection_timeout`	`60 seconds`	When connecting to external industry association or bank interfaces, this value ensures a stable connection establishment duration
`max_tool_call_retry`	`3 times`	Addresses temporary interface fluctuations, preventing single request failures from interrupting overall tasks
`mcp_protocol`	`SSE`	Compatible with MCP tool calling standards version 4.8 and above

The parameter values provided on this page are common starting points for configuration setup. Actual values are influenced by material form, data volume, and business rules. Specific issues require targeted analysis. It is recommended to conduct testing on sample data specific to the deployment before finalizing settings.

Three Common Configuration Errors

A 413 Request Entity Too Large error occurs when calling tools. The cause is that UPLOAD_FILE_MAX_SIZE is not configured or its value is too small, causing the batch-pulled financing daily report data to exceed the interface's allowed request body size.
When using a large language model to call tools, the model cannot be restricted to only trigger plugin calls. The cause is that the tool_call_only configuration item is not enabled, or the model parameters are not correctly set to forced tool calling mode.
An SSE connection cannot be established when configuring MCP tools. The cause is that mcp_server_url and mcp_auth_token are not correctly set, or the SSE connection timeout parameter is configured too short, causing the connection to terminate early.

How to Verify Correct Configuration

Manually trigger a tool call, check if the returned financing daily report data includes required fields such as equipment ID and financing amount, and that units meet preset requirements.
View tool call logs, confirm that no 413 errors are triggered, and that retry counts do not exceed the configured max_tool_call_retry value.
Verify the MCP service connection status, confirm that there are no timeout errors in the SSE connection, and that the latest equipment financing data can be pulled normally.
Check scheduled task execution records, confirm that daily sync tasks are triggered normally, with no duplicate or missing data entries.
