Add the MCP server in one line — then your agent answers crypto questions by calling the API for you. No endpoints to wire up, no keys to juggle. Just ask.

What's the Fear & Greed index today, and how does BTC funding look?

On it — pulling sentiment and derivatives now.

                      ⚙GET/sentiment/fear-greed
                    

                      ⚙GET/derivatives/binance/summary?symbol=BTCUSDT
                    

Fear & Greed is 56 — Neutral. BTC funding is +0.0083%, open interest $7.8B, long/short 1.50. Sentiment is leaning bullish.

Find trending Solana pools and flag anything that looks like a rug.

                      ⚙GET/dex/trending?chain=solana
                    

                      ⚙GET/dex/security/solana/{token}
                    

Top 3 trending: $WIF, $POPCAT, $MEW. Two pass the security check; one new pool flags mint authority not revoked — I'd treat it as high-risk.
