How to Use the Deezer MCP in Pydantic AI

Q: How do I add Deezer to Pydantic AI?

Install pydantic-ai-slimmcp. Initialize an MCPToolset with your Vinkius HTTP URL, then include it in the toolsets array when building your Agent.

Q: Does Pydantic AI validate Deezer MCP Server responses?

Yes. Every piece of data returned by tools like getchart or getartistradio is checked against Pydantic models at runtime to ensure type correctness.

Q: Can I use local models with Deezer and Pydantic AI?

The framework is completely model-agnostic. You can pipe searchtracks results into OpenAI, Anthropic, or any locally hosted LLM without changing your toolset code.

Bring type-safe Deezer catalog searches to your Pydantic AI agents with strict runtime validation.

Type-safe music data with Pydantic AI

You care about correct data, not just fast responses. When your agent calls `get_track`, the framework validates the incoming JSON against strict models. If the API returns a string where an integer duration should be, the system fails loudly. Silent corruption destroys production apps. By wrapping the Vinkius endpoint in an `MCPToolset`, you guarantee that every track, album, and artist record matches your exact schema before your application logic touches it.

Execute strict Deezer MCP Server queries

Connecting this takes minimal effort. You pass the HTTP URL to the unified `MCPToolset` constructor and attach it to your agent. The framework exposes `search_albums` and `search_artists` automatically. Model-agnostic design means you can swap LLMs without rewriting the integration. You might run Claude or a local model, and the agent reliably pulls fan counts and release dates through `get_album_tracks`.

Build reliable playlist generators

Your custom logic needs predictable inputs. An agent can run `get_genre_playlists` to find popular curators, then drill down using `get_playlist` to extract exact track lists. The strict validation ensures preview links and cover art URLs are actually present. You never serve broken images to your users because the framework catches missing fields at runtime.

Setup guide

Set up Deezer 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": {
        "deezer-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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

Common questions about Deezer MCP in Pydantic AI

Install `pydantic-ai-slim[mcp]`. Initialize an `MCPToolset` with your Vinkius HTTP URL, then include it in the `toolsets` array when building your Agent.

Yes. Every piece of data returned by tools like `get_chart` or `get_artist_radio` is checked against Pydantic models at runtime to ensure type correctness.

The framework throws a loud validation error immediately. You will never silently ingest malformed JSON from a `search_playlists` call.

The framework is completely model-agnostic. You can pipe `search_tracks` results into OpenAI, Anthropic, or any locally hosted LLM without changing your toolset code.

It strictly processes public music catalog information like track titles and artist names. Vinkius runs the actual code remotely in an ephemeral V8 isolate, so the server never accesses your local Python environment or memory.
