═══ SUMMARY ═══
POKE6900 is a 9mo old PumpSwap token with $25.9K liquidity and $34.5K market cap.
53 diamond hands (53.0%), strong holder conviction.
Only 18.0% of holders are in profit, most are underwater with avg loss of $844 per wallet.
Buy pressure is strong at 3.3:1 ratio (1093 buys vs 395 sells), accumulation phase.
Contract looks safe: mint and freeze authorities revoked.
🟢 Lower risk profile based on available data.

Why defi-mcp?

Claude Code can write code, fix bugs, deploy apps. But ask it "what's the price of BONK?" and it says "I don't have real-time data."

defi-mcp fixes that. It gives Claude Code real-time access to DeFi data across Solana and 10+ chains.

• Token Analysis with holder intelligence, risk scoring, KOL tracking
• Real-time Prices from DexScreener across all major chains
• Trending Tokens with volume, liquidity, and boost data
• Top Traders showing who made and lost money on any token
• Contract Security checking mint/freeze authority on Solana
• 1.5 second full analysis (not 11 seconds like browser-based scrapers)
• Zero config - no API keys, no wallets, no accounts needed

Quick Start

# Clone and build
git clone https://github.com/0xprotovox/defi-mcp.git
cd defi-mcp
npm install && npm run build

# Add to Claude Code
claude mcp add defi -- node /path/to/defi-mcp/dist/index.js

Then just ask Claude naturally:

> "analyze this token: 3oQw...pump"
> "what's the price of BONK?"
> "show me trending tokens on solana"
> "who made money on JUP token?"

• MCP SDK for Claude Code integration
• curl-based GMGN fetcher bypasses Cloudflare (Playwright fallback if needed)
• In-memory TTL cache prevents rate limiting
• Rate limiter for DexScreener (150 req/min)
• TypeScript with full type safety
