Each tool has a clearly distinct purpose with no overlap: fiat_to_sats handles currency conversion, parse_invoice processes existing invoices, and request_invoice generates new invoices from lightning addresses. An agent can easily distinguish these functions without confusion.

All tool names follow a consistent snake_case pattern with clear verb_noun structures (e.g., parse_invoice, request_invoice). The naming is uniform and predictable across the set.

With only 3 tools, the server feels thin for a Lightning domain, as it lacks operations like sending payments, checking balances, or managing channels. However, the tools are well-scoped for basic invoice and conversion tasks, making it borderline but not severely lacking.

The tool surface is significantly incomplete for Lightning functionality; it covers invoice parsing/requesting and fiat conversion but misses core operations like pay_invoice, get_balance, list_transactions, or channel management. This will likely cause agent failures in broader workflows.
