Perplexity

Validate voice ordering.

The `check_voice_hierarchy` tool validates if voices are in the correct ascending order. For your enterprise agents, this means ensuring that every piece of generated music adheres to strict counterpoint rules. It's a critical safety check for any system building automated musical content. You can trust the data coming out of the Google ADK.

Assess harmonic movement.

`analyze_voice_conduction` analyzes how notes move between two defined chord voicings. This function provides a detailed breakdown, confirming if that conduction follows established classical harmony rules. Because you're building on Google Cloud, this MCP ensures your agents can perform highly specialized data analysis without leaving the secure ecosystem.

Grade transition quality.

`evaluate_smoothness` evaluates the overall fluidity of a musical passage. It doesn't just count notes; it grades the entire transition, which is vital for making music sound natural. This level of detail lets your LlmAgent perform true creative validation, moving beyond simple syntax checking into structural review.

Setup guide

Set up Voice Leading Checker MCP in Google ADK

Prerequisites

Python 3.10+ installed
google-adk package (pip install google-adk)
Active Vinkius subscription with a valid endpoint token

1

Install Google ADK

Run pip install google-adk to install the Agent Development Kit. MCP support is included via the McpToolset class.
2

Connect via SSE transport

Use McpToolset.from_server() with SseServerParams pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create an LlmAgent

Pass the returned mcp_tools list directly to LlmAgent(tools=mcp_tools). The ADK maps each MCP tool to a native Gemini function call — no manual schema definitions required.
4

Run with any Gemini model

The agent works with any Gemini model (gemini-2.0-flash, gemini-2.5-pro, etc.). Copy the full example on the right to get started with Voice Leading Checker tools in your ADK agent.

agent.py

from google.adk.agents import LlmAgent
from google.adk.tools.mcp_tool.mcp_toolset import McpToolset
from google.adk.tools.mcp_tool.mcp_session_manager import SseServerParams

# Connect to the MCP via SSE
mcp_tools, exit_stack = await McpToolset.from_server(
    connection_params=SseServerParams(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    )
)

# Create your agent with auto-discovered tools
agent = LlmAgent(
    name="Voice Leading Checker_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Voice Leading Checker tools via MCP.",
    tools=mcp_tools,
)

Yes. The tool is structured for complex inputs and provides results that can be easily fed into the agent's large context window, maintaining coherence across very long musical passages.

It handles structured musical data, specifically chord voicings and note sequences. The output is a validated JSON object describing the integrity check results.

You can certainly chain these analyses together. For instance, running `analyze_voice_conduction` first, then feeding those results into `evaluate_smoothness` for a deeper review.

It's designed to be rigorous, validating against core counterpoint rules. You get verifiable evidence that the musical output adheres to classical standards, which is key for enterprise applications.
