Budget Tracker by Smart Money

Each tool targets a distinct resource and action: accounts, transactions, budgets, categories, tags, interest, and notifications all have clearly separated operations. The preview_* tools are explicitly paired with their saving counterparts (quick_add, accrue_interest, import_notifications), eliminating confusion between dry-runs and real writes.

The vast majority follow a consistent verb_noun snake_case pattern: create_account, delete_transaction, update_budget, list_categories, preview_interest. The only deviation is 'summary', which is a bare noun rather than get_summary or view_summary, and 'quick_add' uses an adverb+verb construction, but these are minor and do not harm readability.

At 27 tools, the set is heavy and exceeds the typical well-scoped range, but the breadth is justified by the domain: full CRUD for five entities (accounts, transactions, budgets, categories, tags) plus preview/import/interest utilities. It is on the border of being too large, though no tool feels redundant.

The tool surface provides complete lifecycle coverage for all core entities, including create, read, update, delete, and archival for accounts. Additional operations such as interest accrual, notification import, natural-language entry, and summary reporting cover the expected workflows of a personal finance manager without obvious dead ends.
