Overview

AI-generated overview

Free local MCP server that gives an assistant live DeFi yield data — APY and TVL for pools across 60+ chains via DefiLlama.

What you can do
  • List chains that have yield pools, ranked by TVL
  • Fetch top pools by TVL with filters for chain, minimum TVL and stablecoin-only, including total, base and reward APY, 30-day mean and impermanent-loss risk
  • Retrieve every pool for a single protocol across chains
  • Results are cached server-side for five minutes
When to use it
Useful when an assistant should answer questions about DeFi yields, such as the highest-APY pools on a chain, stablecoin farms above a TVL threshold, or how one protocol's APY compares across chains.
Requirements
Runs as a local process started with Node.js 18 or newer; no npm install, no API key and no account. It calls the public DefiLlama yields API, so network access is needed. Configured by pointing an MCP client at the local index.js file.
Before you install
Yield figures come from a third-party public API and are cached for five minutes, so they may lag live markets; base and reward APY are split so incentive-driven rates can be judged. The README promotes a separate paid data marketplace, but this server itself is described as free and needs no credentials or payments.

Installation

In SourceWeft

  1. Open Feegate Yield MCP - Free DeFi APY/TVL data in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

[CI] [Glama MCP Score] [GitHub release] [License: MIT] [Node >=18]

Free, open-source MCP server for DeFi yield data. Search APY / TVL across 60+ chains and 10,000+ pools — no API key, no account, no dependencies.

Data: DefiLlama public yields API · License: MIT · Node.js ≥ 18

🚀 Brought to you by Feegate — the x402 data marketplace where AI agents buy data per call in USDC on Base. Free tools, paid data, no API keys: feegate.org

Why

AI agents (Claude, Cursor, ChatGPT, custom agents) increasingly need live DeFi yield data — "which pools pay the best APY on Base?", "show me stablecoin farms above $50M TVL". This MCP server gives any MCP-compatible client that ability in one config line, for free.

It also demonstrates the Feegate thesis: data should be something an agent can discover, price and call — not something a human has to subscribe to.

Tools

ToolWhat it doesCost
list_chainsAll chains with yield pools, ranked by TVLFree
get_poolsTop pools by TVL, filter by chain / min_tvl / stablecoin_only; returns total/base/reward APY, 30d mean, IL riskFree
get_project_yieldsAll pools of one protocol (e.g. aave-v3), across chainsFree

Results are cached 5 minutes server-side. Each pool includes apy_base vs apy_reward split so agents can avoid unsustainable incentive APYs.

Install (Claude Code / CLI)

bash
claude mcp add feegate-yield -- node /path/to/feegate-yield-mcp/index.js

Cursor / Claude Desktop (mcpServers JSON)

json
{  "mcpServers": {    "feegate-yield": {      "command": "node",      "args": ["/path/to/feegate-yield-mcp/index.js"]    }  }}

No npm install needed — plain Node.js, zero dependencies.

Example questions your agent can now answer

  • "What are the top 10 yield pools on Base by TVL, and which ones are stablecoin?"
  • "Compare Aave v3 APY across chains"
  • "Find stablecoin pools above $50M TVL with the highest base APY (not incentives)"

About Feegate

Feegate turns your data into a product AI agents pay for themselves:

  • x402 v2 payment protocol — HTTP 402 Payment Required + USDC on Base mainnet (EIP-3009, gas sponsored)
  • No accounts, no API keys, no subscriptions — one HTTP round trip per micropayment
  • Listed in the official MCP Registry as io.github.BrianTian818/feegate-yield-mcp (registry.modelcontextprotocol.io); the paid marketplace it complements runs at feegate.org/mcp
  • 20 free self-serve tools (endpoint health check, pricing calculator, GEO generator, launch checklist): feegate.org

This MCP server is free forever. If your agent needs data beyond DeFi yields — market data, research, rankings, monitoring — that's what Feegate sells, per call, in USDC.
