Fetch verified lyrics using Pydantic AI

The `get_lyrics` tool fetches the text of any song based on the artist and title you provide. Pydantic AI validates the structure of the incoming text at runtime, preventing silent data corruption. If the underlying API returns unexpected fields or malformed data, your agent raises a validation error immediately. This guarantees that your application only processes clean, structured lyric strings.

Find song matches with strict type checks

The `suggest_songs` tool returns a list of track suggestions matching your search term. The framework parses this raw JSON response into strongly-typed Python objects before your agent can use them. This prevents your agent from hallucinating properties or trying to access fields that do not exist in the response. You get predictable, type-safe music discovery out of the box.

Connect this MCP Server to any large language model

Both `get_lyrics` and `suggest_songs` work across different model providers when loaded via the unified `MCPToolset`. You don't need to rewrite your tool integration if you switch from OpenAI to Gemini. The server runs externally, and your code connects to it using secure HTTP or SSE transports. This decoupled architecture keeps your application lightweight and easy to test.

Setup guide

Set up Lyrics.ovh 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": {
        "lyricsovh-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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

Common questions about Lyrics.ovh MCP in Pydantic AI

Use the unified MCPToolset class with your Vinkius HTTP endpoint URL. Pass this toolset instance inside the toolsets list when you instantiate your Agent.

The framework validates all incoming data against strict schemas. If the API returns a malformed response, the agent fails loudly with a validation error instead of passing bad data to your model.

Yes, because the framework is model-agnostic. The server exposes the tools via standard protocols, allowing local models to invoke lyric searches just like commercial APIs do.

No, the server is hosted and managed on Vinkius. Your application connects directly to the cloud endpoint, so you do not have to manage any local server processes or dependencies.

The search strings and lyric payloads are transmitted over encrypted TLS. We run the execution environment in a secure sandbox that discards all query data immediately after the tool run completes.
