Scored across 2 tools
The two tools have entirely distinct purposes: generate_audio creates audio from text, while list_voices retrieves available voices. There is no overlap or ambiguity between them.
Both tool names follow a clear verb_noun pattern (generate_audio, list_voices), demonstrating consistent and predictable naming.
With only two tools, the set feels thin for a general-purpose MCP server, though it may be acceptable for a focused streaming service. The count is on the low end of the appropriate range.
The tools cover the core generation and voice discovery workflow, but lack voice management (create/update/delete) and more granular streaming controls. There are minor gaps that could force workarounds in more complex scenarios.
