Index CoinMarketCap data in LlamaIndex

The server pulls live stats via `list_listings` and feeds them into your LlamaIndex vector store. Your agents then perform semantic searches over a dynamic index of market data instead of relying on stale documents. This creates a system where the AI answers questions about asset rankings based on the most recent API pull. It grounds your RAG application in current reality.

Automate LlamaIndex crypto lookups

Use `get_quotes` inside your agent to retrieve current price action that immediately gets indexed. Your knowledge base stays fresh, allowing the AI to cite live data when it answers complex user queries. This MCP server acts as the primary data source for your agentic functions. It ensures that every search returns relevant, market-validated information.

Manage exchange lists with LlamaIndex

Call `list_exchanges` to populate your index with ranked platform information. Your agents use this data to compare exchange stats and provide grounded answers about liquidity or volume. By including this as a tool in your LlamaIndex workflow, you maintain a searchable record of the entire crypto landscape. It keeps your index up to date without manual refreshes.

Convert to LlamaIndex tools
Call mcp_tool_spec.to_tool_list_async() to convert all CoinMarketCap 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 CoinMarketCap tools.",
)
response = await agent.run("List recent CoinMarketCap data")
