Feegate Yield MCP - Free DeFi APY/TVL data

feegate-yield-mcp

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

Tool	What it does	Cost
list_chains	All chains with yield pools, ranked by TVL	Free
get_pools	Top pools by TVL, filter by chain / min_tvl / stablecoin_only; returns total/base/reward APY, 30d mean, IL risk	Free
get_project_yields	All pools of one protocol (e.g. aave-v3), across chains	Free

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)

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

Cursor / Claude Desktop (mcpServers 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.
