Scored across 6 tools
Each tool has a clearly distinct purpose: asking questions, creating expenses, creating invoices, getting bank balances, listing invoices, and getting profit & loss reports. No overlap or ambiguity.
All tools follow a consistent 'penni_verb_noun' pattern using snake_case (e.g., penni_ask, penni_create_expense, penni_get_balance). Perfectly predictable.
With 6 tools covering core bookkeeping operations (read, create, list, report), the count feels well-scoped for a specialized MCP server without being too few or too many.
The tool surface covers essential bookkeeping tasks (query, create expense/invoice, get balances, list invoices, P&L). Missing update/delete operations for expenses and invoices, but the core workflows are covered.
