DeFi Yield Monitor — APY & TVL Alerts (DeFiLlama) MCP

What does DeFi Yield Monitor do?

DeFi Yield Monitor tracks yield farming APY and TVL across 15,000+ DeFi pools on every major chain (Ethereum, Arbitrum, Base, Solana, and 100+ more), powered by the free DeFiLlama yields API. It works in two ways:

1. As an MCP server for AI agents — connect Claude, ChatGPT, or any MCP-compatible agent and let it search pools, pull APY history, spot top movers, and check yield alerts in real time.
2. As a classic Apify Actor — run it with filters and get a clean dataset of pools, or run it on a schedule with alert rules to get notified when yields cross your thresholds.

Disclaimer: This Actor is an unofficial tool and is not affiliated with, endorsed by, or sponsored by DeFiLlama. It uses DeFiLlama's public API as a data source. All output — including APY, TVL, risk flags, and the APY prediction (DeFiLlama's own model output) — is provided for informational purposes only and is not financial, investment, or trading advice, nor an offer or recommendation. DeFi carries significant risk of loss. Always do your own research before depositing funds.

Every pool comes with risk flags included: impermanent-loss risk, stablecoin flag, single/multi-token exposure, and DeFiLlama's APY outlook prediction. No API keys, no browser, no proxies — pure API data with near-100% run reliability.

Why use DeFi Yield Monitor?

• Find the best stablecoin yields — e.g. "all stablecoin pools above 8% APY with at least $10M TVL"
• Give your AI agent DeFi data — yield questions answered live inside Claude or any MCP client
• Get yield alerts on autopilot — schedule runs and pipe alert matches to email, Slack, or webhooks via Apify integrations
• Spot opportunities early — top_movers surfaces pools whose APY jumped (or collapsed) over 1d/7d/30d
• Filter out junk — TVL thresholds and automatic outlier exclusion keep dust pools and fake APYs out of your results

How to use DeFi Yield Monitor

As an MCP server (AI agents)

1. Add the Actor's MCP endpoint to your agent (via Apify's MCP infrastructure or the Actor's standby URL).
2. Your agent can now call these tools:

Tool	What it does
search_pools	Search pools by chain, project, symbol, min APY, min TVL, stablecoin-only; sorted by TVL or APY
pool_history	Full APY/TVL time series for one pool
top_movers	Biggest APY gainers or losers over 1d / 7d / 30d
check_alerts	Evaluate alert rules against live data, returns all matching pools

As a classic Actor (dataset output)

1. Set your filters in the Input tab (chain, project, min APY, min TVL, stablecoin-only, sort, limit).
2. Click Start — matching pools land in the dataset.
3. Download as JSON, CSV, Excel, or HTML, or consume via API.

Recurring yield alerts

1. Fill in Alert rules in the input, for example:

{
    "alertRules": [
        { "label": "stablecoin-8pct", "minApy": 8, "minTvl": 10000000, "stablecoinOnly": true }
    ]
}

2. Create an Apify Schedule (e.g. hourly).
3. Attach an email, Slack, or webhook integration to the Actor — every run pushes current matches to the dataset.

Input

All fields are optional. Without filters you get the top pools by TVL.

Field	Type	Description
chain	string	Exact chain name, e.g. Ethereum, Arbitrum
project	string	DeFiLlama project slug, e.g. aave-v3, lido
symbol	string	Substring match, e.g. USDC
minApy	number	Minimum APY in %
minTvl	number	Minimum TVL in USD
stablecoinOnly	boolean	Only stablecoin pools
sort	string	tvl (default) or apy
limit	number	Max results (default 100)
alertRules	array	Switches to alert mode (see above)

Example presets

Copy any block into the Input tab (JSON editor) and hit Start. Each one is a ready-made starting point — tweak the numbers to taste.

Safe stablecoin income — low-volatility pools with solid TVL, highest APY first:

{
    "stablecoinOnly": true,
    "minApy": 6,
    "minTvl": 20000000,
    "sort": "apy",
    "limit": 50
}

High-yield hunter — chase the top APYs, dust pools filtered out (higher risk):

{
    "minApy": 20,
    "minTvl": 1000000,
    "sort": "apy",
    "limit": 100
}

Blue-chip single protocol — watch one project on one chain (e.g. Aave v3 on Ethereum):

{
    "chain": "Ethereum",
    "project": "aave-v3",
    "sort": "tvl",
    "limit": 50
}

Recurring stablecoin alert — alert mode: attach an Apify Schedule plus an email/Slack integration and get pinged whenever a pool crosses your thresholds:

{
    "alertRules": [
        { "label": "stablecoin-8pct", "minApy": 8, "minTvl": 10000000, "stablecoinOnly": true },
        { "label": "eth-blue-chip-5pct", "chain": "Ethereum", "project": "aave-v3", "minApy": 5 }
    ]
}

Output

One record per pool:

{
    "poolId": "747c1d2a-c668-4682-b9f9-296708a3dd90",
    "chain": "Ethereum",
    "project": "lido",
    "symbol": "STETH",
    "tvlUsd": 17177564785,
    "apy": 2.15,
    "apyBase": 2.15,
    "apyReward": null,
    "apyPct1D": -0.07,
    "apyPct7D": -0.03,
    "apyPct30D": -0.24,
    "stablecoin": false,
    "ilRisk": "no",
    "exposure": "single",
    "prediction": "Stable/Up",
    "predictionProbability": 70,
    "url": "https://defillama.com/yields/pool/747c1d2a-c668-4682-b9f9-296708a3dd90"
}

How much does it cost?

Pay-per-event pricing — you only pay for what you use:

Event	Price	When
Actor start	$0.005	Each classic (non-MCP) run
MCP tool call	$0.01	Each tool call from your agent
Pool result	$0.004	Each pool in a classic run's dataset
Alert match	$0.01	Each pool matching an alert rule in alert mode

Example: a daily stablecoin-yield digest of 20 pools costs about $2.55/month. An agent asking 100 yield questions costs $1.00. An hourly alert schedule averaging 2 matches per run costs about $18/month.

Tips

• Set minTvl to at least 1000000 — sub-$1M pools often show unsustainable APYs.
• Use sort: "apy" with a minTvl floor to find the best credible yields.
• Watch the prediction field: Down means DeFiLlama's model expects the APY to fall.
• Keep alert rules tight (high minApy + high minTvl) so you only pay for matches you care about.

FAQ & support

Where does the data come from? The public DeFiLlama yields API — the same data as defillama.com/yields.

Is this financial advice? No. APY and risk flags are raw data; always do your own research before depositing funds.
