Scored across 2 tools
The two tools target clearly distinct functions: one checks aggregate payer spend/delivery health, while the other audits a single payment and returns a signed receipt. Their descriptions are specific enough that an agent should not confuse them.
Both tool names are snake_case and descriptive, though payer_spend_health is a noun phrase while verify_payment_receipt uses a verb-object form. The minor stylistic deviation does not hurt readability.
Two tools is slightly below the typical 3-15 range, but it is appropriate for a narrow read-only receipt verification domain. Each tool covers a distinct core use case without seeming padded.
The server covers the main verification workflows: validating one payment and summarizing payer-level delivery health. Batch verification or broader receipt-log queries would be useful additions, but the core domain is not left with a dead end.
