Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@feegate-yield-mcp find stablecoin pools on Base above $50M TVL with the highest base APY"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
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.

🚀 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
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.

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

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.

Get top DeFi yield pools ranked by TVL, filtered by chain. Returns APY (total / base / reward), TVL, stablecoin flag and IL risk for each pool. Data: DefiLlama, updated continuously, cached 5 min. Free, no API key.
Inputs: chain, limit, min_tvl, stablecoin_only.
Get all yield pools of one DeFi project/protocol (e.g. "aave-v3", "curve-dex"), across all chains, ranked by TVL.
Inputs: project (required), limit.
List all chains that have DeFi yield pools, with pool counts and total TVL. Use this first to discover which chains are available before calling get_pools.
Inputs: no named parameters.

Scored across 3 tools
Each tool targets a clearly distinct dimension: chains, pools-by-chain, and pools-by-project. The descriptions explicitly direct the agent to call list_chains before get_pools, reinforcing correct selection. No meaningful overlap exists between the three operations.
All tool names follow a consistent verb_noun pattern: list_chains, get_pools, get_project_yields. The verbs are predictable and the nouns clearly identify the returned resource.
Three tools is on the low end but reasonable for a narrowly scoped DeFi yield reader. Each tool earns its place, though one or two additional query or filter tools could round out the surface.
The core discovery workflow—list chains, then fetch pools by chain or by project—is fully covered. Minor gaps exist around filtering by APY, stablecoin status, or IL risk directly in the tool surface, but users can post-process the returned data.
