What is the DefiLlama (DeFi Analytics) MCP Server?
Connect your AI agent to DefiLlama, the leading aggregator for decentralized finance data. This server allows you to query real-time and historical metrics across the entire DeFi ecosystem through natural conversation.
What you can do
- TVL Analytics — Track Total Value Locked (TVL) for specific protocols, individual chains, or the global DeFi market.
- Token Pricing — Retrieve current and historical prices, generate price charts, and calculate percentage changes for thousands of tokens.
- Yield & Pools — Monitor APY and TVL for liquidity pools to identify the best yield farming opportunities.
- Volume & Liquidity — Analyze DEX volumes, bridge activity, and stablecoin market caps across different ecosystems.
- Historical Deep-Dives — Access time-series data to understand market trends and protocol growth over time.
How it works
- Subscribe to this server
- (Optional) Enter your DefiLlama API Key if you have a pro account, or leave blank for public access
- Start analyzing the DeFi markets directly from your AI client
Who is this for?
- Crypto Analysts — perform deep on-chain research and protocol comparisons without manual data scraping
- DeFi Developers — integrate real-time price and TVL data into your development workflow
- Portfolio Managers — track market trends and yield opportunities across multiple chains instantly

Why OpenAI Agents SDK?
The OpenAI Agents SDK auto-discovers all 19 tools from DefiLlama (DeFi Analytics) through native MCP integration. Build agents with built-in guardrails, tracing, and handoff patterns. chain multiple agents where one queries DefiLlama (DeFi Analytics), another analyzes results, and a third generates reports, all orchestrated through Vinkius.

Why teams choose Vinkius for DefiLlama (DeFi Analytics) in OpenAI Agents SDK
The DefiLlama (DeFi Analytics) MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 19 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in OpenAI Agents SDK only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

* Every MCP server runs on Vinkius-managed infrastructure inside AWS - a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts optimized for native MCP execution. See our infrastructure
How Vinkius secures
DefiLlama (DeFi Analytics) for OpenAI Agents SDK
Every tool call from OpenAI Agents SDK to the DefiLlama (DeFi Analytics) MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
How can I check the current TVL of a specific blockchain like Ethereum or Solana?
You can use the get_current_tvl_chain tool by providing the chain name. The agent will return the total value locked in USD for that specific network immediately.
Is it possible to see a price chart for a specific token?
Yes! Use the get_price_chart tool with the token's chain and address (e.g., ethereum:0x...). It will provide historical price data points that your agent can use to describe trends.
How do I find the highest yielding liquidity pools available?
The get_all_pools tool retrieves current APY and TVL data for all tracked pools. Your agent can then filter and sort these to find the best opportunities based on your criteria.
How does the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
