Perplexity

Verify voice ordering.

The `check_voice_hierarchy` tool validates if individual voices move in the correct ascending order. With Pydantic AI, you get a guaranteed failure message if the notes violate established rules; no silent errors here. This type-safe checking is perfect when your agent's output must be 100% musically accurate before it moves to another system.

Assess harmonic movement.

`analyze_voice_conduction` analyzes the progression between two specific chord voicings. The result is always validated against a Pydantic model, so you never have to worry about unexpected data fields. It makes building reliable, production-grade musical agents much simpler because you know exactly what structure your inputs and outputs will take.

Grade transition quality.

`evaluate_smoothness` measures the overall fluidity of a passage. Because every MCP response validates against Pydantic models, this score is reliable and predictable. It means your agent can make high-stakes decisions based on guaranteed correct data. It's correctness over speed that matters here.
