base_get_defi_opportunities

Use this when you need DeFi yield opportunities specifically on Base chain. Returns Base-native protocol yields in JSON. POST variant of base_get_defi_opportunities -- same params passed as JSON body instead of query string. 1. opportunities: array of yield farms ranked by APY 2. protocol: protocol name (Aerodrome, Moonwell) 3. pool: pool name and token pair 4. apy: current annual percentage yield 5. tvl: total value locked in USD 6. riskScore: risk rating (1-10, lower is safer) 7. type: yield type (LP, lending, staking) Example output: {"opportunities":[{"protocol":"Aerodrome","pool":"USDC/WETH","apy":18.5,"tvl":45000000,"riskScore":3,"type":"LP"},{"protocol":"Moonwell","pool":"USDC Lending","apy":5.2,"tvl":120000000,"riskScore":1,"type":"lending"}],"chain":"base","totalPools":12} Use this FOR deploying capital on Base chain specifically. Curated list of vetted Base-native protocols only. Do NOT use for multi-chain yields -- use defi_find_best_yields instead. Do NOT use for swap quotes on Base -- use dex_get_swap_quote instead. Do NOT use for liquidation risk -- use defi_get_liquidation_levels instead.

Base DeFi Yield Optimizer API — questions

Answers built from our own checks of this server.

What can Base DeFi Yield Optimizer API do?

It exposes 1 tools, read directly from the server on our last check. Among them: base_get_defi_opportunities. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Base DeFi Yield Optimizer API working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 8 ms. The bar chart above shows every period we have measured.

The registry lists Base DeFi Yield Optimizer API as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Base DeFi Yield Optimizer API?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Base DeFi Yield Optimizer API need an API key?

No. Base DeFi Yield Optimizer API completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.

Is Base DeFi Yield Optimizer API open source?

The code is open source: it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at base-defi.api.klymax402.com, which runs on its operator's own terms.
