Defi Garden MCP Server

🌱 DeFi Garden

Calm, honest DeFi yield discovery and goal-based savings planning.

DeFi Garden is a static, zero-backend, zero-build-step web application built on the DefiLlama yields API, designed for cautious savers and DeFi operators who value trust, realistic projections, and mathematical transparency over speculative hype.

🌟 The Two Core Faces of DeFi Garden

DeFi Garden serves two distinct workflows through an inline, zero-flash IA router (window.__APP_MODE in home.html):

1. 🪴 Garden Planner (Default Experience — / and plan.html)

• Goal-First Conversational Savings: Plan savings around real-life goals (subscriptions, gadgets, life milestones) rather than chasing abstract APY numbers.
• Yield-Funded Paradigm: "Buy it outright and the money's gone. Garden it and you keep the money AND get the thing."
• Blended Yield Rates: Calculates honest "forever numbers" — the capital required so ongoing live yield pays recurring bills automatically.
• Degen Honesty: Applies a mandatory ⅓ decay haircut to variable farm/reward emissions, ensuring users plan around realistic long-term carry.

2. 📊 Analytics & Yield Discovery (/?token=, /?chain=, /?pool=, /?app=1)

• Multi-Chain Pool Explorer: Real-time yield monitoring across 50+ blockchains (Ethereum, Arbitrum, Base, Hyperliquid, Solana, etc.) and all major protocol types (Lending, Staking, LP/DEX, Yield Farming).
• Deep Pool Breakdown (PoolDetail.js): In-depth pool analytics, 30-day mean APY tracking, base vs. reward emission separation, and impermanent loss risk indicators.
• Funding Harvest Module (/hype-harvest.html / /?module=hype-harvest): Delta-neutral cash-and-carry funding harvest calculator for Hyperliquid perps with live basis spread tracking and dual-oracle divergence tripwires.

🛡️ Trust Rails (The Core Moat)

Every metric rendered across DeFi Garden derives from live on-chain and API data through strict, non-negotiable trust rails:

1. APY_SANITY_LIMIT = 1000%: Anomalous, short-lived spikes can never enter a plan. In analytics, anomalous pools are demoted, flagged with ⚠, and forced to high-risk classification.
2. DEFAULT_MIN_TVL = $100K: Low-liquidity pools below the safety floor are filtered out to protect savers from illiquid exits and sudden deprecations.
3. Dual-Oracle Divergence Guard: Modules verify mark vs. oracle price divergence ($<15\text{ bps}$ tripwire) to alert on basis dislocation and squeeze risk.
4. Deterministic Math Layer: LLMs may narrate or explain mechanisms, but numbers, projections, and compounded yields are calculated deterministically.

🎨 Design System — "Quiet"

DeFi Garden uses the "Quiet" design system — a restrained, clean-minimal, table-first interface designed for clarity and focus:

• Surface Tokens (--ui-*):
  • Backgrounds: --ui-bg (#F7F8FA light / #161A20 dark), --ui-surface (#FFFFFF / #1E242C), --ui-surface-muted, --ui-surface-sunken.
  • Separation: Single-pixel hairline borders (--ui-border: #E4E7EE, --ui-border-strong: #CBD2DF).
  • Text: High-contrast hierarchy (--ui-text: #10151F, --ui-text-secondary: #5A6478, --ui-text-muted: #8A93A6).
  • Accents: Fixed trust-blue palette (--ui-accent: #3B82F6, --ui-accent-hover: #2563EB, --ui-accent-soft: #EFF5FF).
  • Radii: Clean geometric squircles (--ui-radius-sm: 8px, --ui-radius-md: 12px, --ui-radius-lg: 16px, --ui-radius-pill: 999px).
• No Heavy Shadows or Skeuomorphic Skeins: Depth is created through crisp hairline borders and subtle surface tone steps, not artificial dual-direction shadows or background gradients.
• Physical Press Physics: Interactive controls sink 1px on :active (transform: translateY(1px)), respecting prefers-reduced-motion.
• First-Class Bilingual Support (translations.js): Complete English (en) and Korean (ko) localization synchronized across all user-facing strings.

🛠️ Architecture & Technology Stack

• Zero Build Step: Runs natively on vanilla web standards. React 18 UMD loaded via script tag; components written in pure React.createElement (no JSX compilation step required).
• Data Ingestion: Client-side integration with https://yields.llama.fi/pools and Hyperliquid Info API (https://api.hyperliquid.xyz/info).
• State Management:
  • Theme: localStorage.getItem('theme') with data-theme="light|dark" attribute on <html>.
  • Language: URL param ?lang= + localStorage.getItem('defi-garden-lang').
  • Saved Plan: localStorage.getItem('garden-plan').
• SEO & Machine Readability:
  • Automated dynamic sitemaps (generate-sitemap.js).
  • AI Context endpoints: llms.txt and llms-full.txt (generate-llms.js).
  • Model Context Protocol (MCP) server integration (mcp_server.js).
