How to Use the Lyrics.ovh MCP in LangChain

Q: Can a LangChain agent chain suggestsongs and getlyrics together?

Yes, your agent does this automatically. It uses suggestsongs to find the correct artist and title, then passes those variables directly into getlyrics in the next step of the chain.

Q: How does LangSmith monitor Lyrics.ovh API calls in a LangChain project?

LangSmith logs every single execution of getlyrics and suggestsongs automatically. You can inspect the input parameters, execution latency, and raw text output of your music queries directly in your LangSmith dashboard.

Build multi-step music reasoning chains in LangChain using instant song suggestions and lyric retrieval.

Build song-discovery chains with LangChain

The `suggest_songs` tool feeds raw track suggestions directly into your LangChain decision loops. Your agent takes a vague user mood, queries the endpoint, and instantly parses the list to select the best match without manual intervention. This setup lets you pass the selected track straight into the next step of your chain. You get a fluid pipeline where the output of your song search feeds your downstream prompts automatically.

Extract full lyrics inside LangGraph agents

The `get_lyrics` tool retrieves the exact text of any song directly during agent execution. Your LangGraph agent checks the lyrics for specific themes or sentiment, making it easy to categorize music libraries on the fly. LangSmith tracks the latency and token usage of these lyric requests in real time. You see exactly when the agent calls the server and how much data passes through the chain.

Multi-step music lookup via this MCP Server

This MCP Server lets your LangChain agent run a two-step lookup by combining both tools in a single run. The agent first queries `suggest_songs` to resolve a messy user query, then immediately fires `get_lyrics` to fetch the complete text. You configure this behavior by passing the server tools to your ReAct agent initialization. The agent decides when to search and when to pull the full text based on what the user asks.

Setup guide

Set up Lyrics.ovh MCP in LangChain

Prerequisites

Python 3.10+ installed
langchain-mcp-adapters + langgraph packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install langchain-mcp-adapters langgraph langchain-openai. The MCP adapters package converts MCP tools into native LangChain BaseTool objects.
2

Connect via HTTP transport
Use MultiServerMCPClient with "transport": "http" pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create a ReAct agent
Pass the discovered tools to create_react_agent() from LangGraph. The agent automatically routes Lyrics.ovh tool calls through the MCP protocol.
4

Run with any LLM
Swap ChatOpenAI for ChatAnthropic, ChatGoogleGenerativeAI, or any LangChain-compatible model. The MCP tools work identically across all providers.

agent.py

from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain_openai import ChatOpenAI

async with MultiServerMCPClient({
    "lyricsovh-mcp": {
        "transport": "http",
        "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp",
    }
}) as client:
    tools = client.get_tools()

    agent = create_react_agent(
        ChatOpenAI(model="gpt-4o"),
        tools,
    )
    result = await agent.ainvoke({
        "messages": "List recent Lyrics.ovh transactions"
    })
    print(result["messages"][-1].content)

Common questions about Lyrics.ovh MCP in LangChain

You initialize the MCP client with the server URL and call get_tools to retrieve the tools. Then, pass this list directly to your LangChain agent constructor to let it call `suggest_songs` or `get_lyrics`.

Yes, your agent does this automatically. It uses `suggest_songs` to find the correct artist and title, then passes those variables directly into `get_lyrics` in the next step of the chain.

LangSmith logs every single execution of `get_lyrics` and `suggest_songs` automatically. You can inspect the input parameters, execution latency, and raw text output of your music queries directly in your LangSmith dashboard.

The MCP integration is stateless by default, but you can use client.session() to keep context alive across multiple lyric searches. This helps your agent remember previous song suggestions during a long conversation.

Your song titles and artist queries go straight to the API without being stored on Vinkius. The server runs inside an isolated sandbox, keeping your music search history private and ephemeral.
