Best MCP servers for DeFi yield data, ranked October 2026
Is there an MCP server that lets Claude or ChatGPT look up DeFi yields?
Yes: four are ranked here for October 2026 on whether you can try them free, whether they need a key, whether they can move money and what yield tools they offer, and web3juice (which we make) is ranked first. The other facts were checked on 21 October 2026 or, where marked, on 16 October 2026.
An MCP server lets an assistant such as Claude, ChatGPT, Cursor or VS Code Copilot call a tool instead of guessing. For yields, three things matter: the figures are dated, the server cannot move money, and you can try it without a paid plan.
Full disclosure: we make web3juice, and it is ranked first below, so weigh our view accordingly. We judged only four things: whether you can try the server free, whether it needs a key, whether it can move money, and what yield tools it offers. Facts about other tools come from their own public pages, checked on 21 October 2026 unless a row says otherwise (rows dated 16 October 2026 come from the pages behind our comparison pages). This list quotes no rates and is not a list of places to deposit.
How do the four DeFi MCP servers compare feature by feature?
| Rank | Server | Price to use it | Key or plan needed | Transactions | Yield tools |
|---|---|---|---|---|---|
| 1 | web3juice | Free; higher limits and your own workspace with Pro (£10/month) | No key for the research tools | Read-only: cannot sign or prepare a transaction | Market overview, pool search, pool details with the base and reward split, 7, 30 and 90-day history, compare 2 to 5 pools, data freshness and methodology |
| 2 | DefiLlama | API plan: $300 a month or $3,000 a year | The API plan | Not described on its plans page | MCP access to its data for AI agents; the plans page lists no tool names |
| 3 | vaults.fyi | API key from its portal, or pay-per-request (x402) on Base with no key; plan prices not shown | An API key, or x402 | Tools can build deposit and withdraw transactions; the client signs and submits | 38 tools covering vault data, history, positions and transactions |
| 4 | Bitcompare (16 Oct) | Pro API plan, $499 a month; a free trial covers MCP | The Pro API plan | Read-only tools | 18 tools for CeFi and DeFi rates |

Why is each server where it is?
1. web3juice
Free to start, and the research tools need no key: add https://web3juice.com/api/mcp to Claude Code, Claude Desktop (through npx -y web3juice-mcp), Cursor or VS Code, or connect it in Claude.ai or ChatGPT developer mode. The free limit is 500 calls a day. Every figure it returns carries its retrieval time, and it can never move funds. It is listed in the official MCP Registry as com.web3juice/mcp. With a Pro key your assistant can also read your own alerts and notebook. See AI assistants (MCP) and web3juice vs vaults.fyi.
2. DefiLlama
Second: the widest dataset, but its plans page puts MCP access on the API plan at $300 a month ($3,000 a year). See web3juice vs DefiLlama.
3. vaults.fyi
Third for research use: a large toolset for builders, including tools that build deposit and withdraw transactions for your client to sign. Aimed at developers building products more than at an assistant doing research. See web3juice vs vaults.fyi.
4. Bitcompare
Fourth: MCP access with 18 read-only tools, on its top API plan. See web3juice vs Bitcompare.
How do you try it?
Ask your assistant: “Compare the three largest USDT pools on Arbitrum, with their 30-day ranges.” Setup steps for each client are on the AI assistants (MCP) page.

Research and monitoring only: web3juice never holds funds, asks for keys or executes trades. APYs change constantly and are not a promise of returns. Principal can be lost. Nothing on this page is financial advice.
Connect your assistant
Add the web3juice MCP server to Claude, ChatGPT, Cursor or VS Code and ask it about DeFi yields. Free and read-only.
