How to Use the Genius MCP in LlamaIndex

Q: How do I register the Genius MCP Server in LlamaIndex?

Install llama-index-tools-mcp. Set up a BasicMCPClient with your endpoint, wrap it in McpToolSpec, and call totoollistasync() to feed the tools to your FunctionAgent.

Q: Can LlamaIndex cache Genius lyric searches?

You build the caching layer by indexing the output of getsong. Once the full plain text or HTML lyrics are in your vector store, subsequent queries hit your local index.

Q: How does LlamaIndex handle Genius pagination?

Tools like getartistsongs require a page parameter. Your agent iterates through the pages, pulling down song titles and URLs until the index is fully populated.

Q: Can I restrict which Genius tools LlamaIndex uses?

Provide an allowedtools list when initializing the spec. You might want to expose getalbum while blocking heavy text endpoints like getsongannotations.

Index massive discographies and community annotations directly into your LlamaIndex vector stores.

Index Genius Annotations for RAG

`get_song_annotations` retrieves community-written explanations for lyric fragments. LlamaIndex takes these raw JSON responses and converts them into queryable document nodes inside your local vector store. You run a semantic search against the resulting index. Instead of just returning a raw lyric, your RAG application answers questions about wordplay and references using the actual vote counts and author info from the Genius database.

Search and Store with the MCP Server

`search_songs` locates tracks by title or lyrics across the Genius platform. Your LlamaIndex function agent executes the search and immediately indexes the returned pageview counts and URLs. When users ask about popular tracks, the agent queries your local vector store rather than hitting the API a second time. You combine live API data with static documents to build a unified music knowledge base.

Build Artist Knowledge Bases

`get_artist` pulls down profile images, IQ scores, and descriptions. You pair this with `get_album` to ingest complete release histories, track lists, and cover art into your index. The agent cross-references these details during query time. If a user asks about a specific release date, LlamaIndex pulls the exact metadata retrieved from the API, eliminating hallucinations entirely.

Setup guide

Set up Genius MCP in LlamaIndex

Prerequisites

Python 3.10+ installed
llama-index-tools-mcp package
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install llama-index-tools-mcp llama-index-llms-openai. The MCP tools package provides BasicMCPClient and McpToolSpec.
2

Connect with BasicMCPClient
Point BasicMCPClient to your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports SSE and Streamable HTTP transports.
3

Convert to LlamaIndex tools
Call mcp_tool_spec.to_tool_list_async() to convert all Genius MCP tools into native FunctionTool objects that any LlamaIndex agent can use.
4

Run with any LLM
Create a FunctionAgent with the tools and your preferred LLM. Swap OpenAI for Anthropic, Gemini, or any LlamaIndex-supported provider.

agent.py

from llama_index.tools.mcp import BasicMCPClient, McpToolSpec
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

# Connect to the MCP
mcp_client = BasicMCPClient(
    "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)
mcp_tool_spec = McpToolSpec(client=mcp_client)

# Convert MCP tools to LlamaIndex tools
tools = await mcp_tool_spec.to_tool_list_async()

# Create and run the agent
agent = FunctionAgent(
    tools=tools,
    llm=OpenAI(model="gpt-4o"),
    system_prompt="You have access to Genius tools.",
)
response = await agent.run("List recent Genius data")
