How to Use the Dextools (DeFi Token Data API) MCP in LlamaIndex

Q: How does LlamaIndex index the data returned by the Dextools (DeFi Token Data API) MCP Server?

The McpToolSpec converts tool outputs like gettoken directly into document nodes. LlamaIndex then parses these nodes, allowing you to run semantic searches over live DeFi metadata.

Q: Can I limit which tools my agent can access from this MCP Server?

Yes, you can restrict access. Use the allowedtools filter during your LlamaIndex setup to expose only specific tools like gettokenprice while blocking liquidity endpoints.

Q: How do I handle cross-chain token queries using Dextools (DeFi Token Data API) in LlamaIndex?

You use the getblockchains tool to retrieve valid network identifiers first. Your LlamaIndex router then passes the correct network parameter to getpair over the MCP connection.

Index real-time DeFi token data and liquidity pools directly into your LlamaIndex vector store.

Feed LlamaIndex RAG with Real-Time Prices

The `get_token_price` tool fetches current market rates to update your local document index on the fly. Your LlamaIndex pipeline queries this tool to ground conversational responses in current market realities. By writing these outputs directly to your vector store, you prevent your agent from hallucinating old pricing data during user chats.

Structure Liquidity Records for Semantic Search

The `get_token_liquidity` tool retrieves the exact pool reserves for any given token contract. Your agent reads this data to flag low-liquidity pairs before they enter your search index. Pairing this with `get_pair` gives you a clear picture of pool health across multiple networks. LlamaIndex uses these structured records to answer complex quantitative queries about pool stability.

Verify Smart Contracts via MCP Server

The `get_token` tool extracts verified smart contract details, including symbol, name, and total supply metrics. Your agent runs this check to catalog new tokens as they launch. Combining this metadata with `get_blockchains` allows your LlamaIndex pipeline to organize your knowledge base by network. This prevents cross-chain naming collisions in your database.

Setup guide

Set up Dextools (DeFi Token Data API) 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 Dextools (DeFi Token Data API) 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 Dextools (DeFi Token Data API) tools.",
)
response = await agent.run("List recent Dextools (DeFi Token Data API) data")
