Summary of ChangesHello @skynet2, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request introduces a crucial fix for service token generation, allowing the Time-To-Live (TTL) to be specified dynamically per request, enhancing control over token validity. Concurrently, it significantly refactors the transaction category management system by replacing single-transaction updates with a more efficient bulk operation. This change streamlines the process of assigning or clearing categories for multiple transactions, reducing API calls and optimizing database performance. The accompanying tests have been thoroughly updated to validate these new functionalities. Highlights

Code Review
The pull request introduces a significant improvement by refactoring the transaction category setting functionality from a single-transaction operation to a bulk operation. This change is implemented across pkg/mcp/server.go and pkg/mcp/transaction_category_tool.go, along with corresponding updates in pkg/mcp/transaction_category_tool_test.go. Additionally, the JWT service token generation now correctly uses the requested TTL, and the associated test has been enhanced to verify the expiration time. A minor update to pkg/testingutils/gorm.go adds 'tools.lan' to allowed database hosts. Overall, the changes improve functionality, test coverage, and code clarity, though a potential silent failure in the bulk update needs addressing.

The current implementation of the bulk update for category_id will silently succeed even if a transaction_id provided in the assignments array does not exist in the database. GORM's Update method returns nil error and RowsAffected as 0 when no records match the Where clause, rather than an error. This can lead to a misleading success message (e.g., "Updated 3 transactions") when some updates actually failed because the transaction IDs were invalid. It's important to explicitly check RowsAffected to ensure that the update was successful for each transaction.
Consider adding a check for RowsAffected after each update operation to verify that a transaction was indeed updated. If RowsAffected is 0, it indicates that the transaction ID was not found, and an appropriate error should be returned for that specific assignment.
result := s.db.WithContext(queryCtx).Table("transactions").Where("id = ?", int64(txID)).Update("category_id", categoryID)
if result.Error != nil {
return mcp.NewToolResultError(fmt.Sprintf("failed to update transaction %d: %v", int64(txID), result.Error)), nil
}
if result.RowsAffected == 0 {
return mcp.NewToolResultError(fmt.Sprintf("transaction %d not found or not updated", int64(txID))), nil
}
