Type-safe audio mixing with Pydantic AI

Run `create_mix` knowing the response matches your expected schema. Pydantic AI validates every field returned by the MCP Server at runtime. Avoid silent errors by letting the framework reject invalid data. If the server returns a malformed URL or status, the agent raises an immediate validation error.

Validated voice selection in Pydantic AI

Request `list_voices` and let the agent parse the output against your defined models. This prevents hallucinated fields from entering your audio workflow. Check `get_voice_details` to verify speaker metadata. The system forces strict compliance with your data structure, ensuring reliable voice selection.

Monitor production in Pydantic AI

Use `list_media_files` to catalog your output with total accuracy. The framework ensures that every file reference adheres to your strict typing rules. Call `get_usage_analytics` to track your account status. Pydantic AI handles the response parsing, giving you a clean data object to process.

Setup guide

Set up AudioStack MCP in Pydantic AI

Prerequisites

Python 3.10+ installed
pydantic-ai-slim[fastmcp] package
Active Vinkius subscription with a valid endpoint token

1

Install Pydantic AI with FastMCP
Run pip install "pydantic-ai-slim[fastmcp]". The FastMCP toolset replaces the deprecated MCPServerHTTP class with full protocol support.
2

Configure the FastMCPToolset
Pass a JSON-style config dict to FastMCPToolset with your Vinkius URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports Streamable HTTP, SSE, and Stdio transports.
3

Create and run your agent
Pass the toolset to Agent(toolsets=[toolset]) and call agent.run(). Swap openai:gpt-4o for any supported model — Anthropic, Google, Mistral, or Groq.

agent.py

from pydantic_ai import Agent
from pydantic_ai.toolsets.fastmcp import FastMCPToolset

toolset = FastMCPToolset({
    "mcpServers": {
        "audiostack-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

agent = Agent(
    "openai:gpt-4o",
    toolsets=[toolset],
    system_prompt="You have access to AudioStack tools.",
)

result = await agent.run("List recent AudioStack transactions")
print(result.output)
