How to Use the DefiLlama (DeFi Analytics) MCP in OpenAI Agents SDK

Q: How do I connect DefiLlama (DeFi Analytics) to OpenAI Agents SDK?

Pass MCPServerStreamableHttp into the mcpservers array. Tools auto-discover without manual mapping.

Q: Can DefiLlama (DeFi Analytics) with OpenAI Agents SDK track historical APY?

Yes. Call getpoolhistoricaldata within your agent's context. The SDK logs the exact yield curve the model analyzed.

Q: Does the OpenAI Agents SDK cache DefiLlama (DeFi Analytics) endpoints?

Set cacheToolsList=True in your server parameters. That prevents the agent from fetching the schema on every single turn.

Build production DeFi agents with OpenAI Agents SDK that validate TVL drops and stablecoin pegs before executing trades.

Track TVL shifts with OpenAI Agents SDK

`get_historical_tvl_chain` and `get_protocols` let your agent pull exact liquidity metrics across the entire DeFi space. Developers configure the MCP server as `mcp_servers=[server]` in the constructor, and the model auto-discovers these endpoints instantly. Guardrails built into the framework validate the data before your agent makes a move. If `get_current_tvl_chain` shows a sudden 40% drop on Arbitrum, the system flags the anomaly instead of blindly passing it to a downstream trading module.

Historic price and yield analysis

`get_historical_prices` feeds timestamp-specific token valuations directly into your execution traces. Teams track exactly what the agent knew at a specific block time using the OpenAI dashboard. Handoffs work perfectly with these MCP tools. A research agent runs `get_all_pools` to find the highest APY, then passes the exact contract address and yield data to a specialized execution agent.

Cross-chain volume monitoring

`get_bridge_volume_chain` gives your Python scripts hard numbers on capital flight between networks. Set `cacheToolsList=True` to keep these frequent polling operations fast. Stablecoin pegs matter in production. The model can call `get_stablecoin_market_cap_chain` on a loop, letting the SDK's safety constraints trigger alerts the second USDC supply shifts off-chain.

Setup guide

Set up DefiLlama (DeFi Analytics) MCP in OpenAI Agents SDK

Prerequisites

Python 3.10+ installed
openai-agents package (pip install openai-agents)
Active Vinkius subscription with a valid endpoint token

1

Install the SDK

Run pip install openai-agents to install the OpenAI Agents SDK. The MCP integration is built-in — no extra dependencies needed.
2

Connect via SSE transport

Use MCPServerSse with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. The SDK auto-discovers all DefiLlama (DeFi Analytics) tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives DefiLlama (DeFi Analytics) tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate DefiLlama (DeFi Analytics) tools and returns structured results. Copy the full example on the right to get started.

agent.py

import asyncio
from agents import Agent, Runner
from agents.mcp import MCPServerSse

async def main():
    async with MCPServerSse(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ) as server:
        agent = Agent(
            name="DefiLlama (DeFi Analytics) Agent",
            instructions="You have access to DefiLlama (DeFi Analytics) tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())
