A4.4/5.0
Scored across 1 tool
Disambiguation5/5
With a single tool there is nothing to confuse it with; the tool's purpose (text-to-speech synthesis) is unmistakable from its name and description. An agent will always select it correctly for speech generation.
Naming Consistency5/5
The lone name 'speak' is a clear lowercase verb that reads naturally as an action. There is no competing convention to create inconsistency, and it is self-explanatory.
Tool Count4/5
One tool is essentially correct for a narrowly scoped TTS server, and the description packs the parameters (voice, speed, format, chunking guidance) into that single entry. It is slightly thin in that a companion voice-discovery tool would have been a natural second member of the set.
Completeness3/5
Synthesis itself is fully covered, including long-text chunking guidance, but the surface offers no way to enumerate the advertised 38 voices or their language mappings, leaving agents to guess voice identifiers. That is a notable gap even though a default voice makes the tool usable.
Available Tools
