Jupiter

MCP server for the Jupiter Developer Platform — 17 tools covering swap, tokens, price, lend, limit orders, DCA, prediction markets, perps, and portfolio.

Any MCP-compatible AI agent (Claude Code, Cursor, ChatGPT, etc.) gets native access to Jupiter's full DeFi stack on Solana.

Example

You: "What's the price of SOL and JUP?"

Agent calls: jupiter_price({ mints: "So11...112,JUPyi...vCN" })

→ SOL: $83.53 (-2.4% 24h), JUP: $0.166

You: "Get me a quote to swap 1 SOL for USDC"

Agent calls: jupiter_swap_quote({
  inputMint: "So11111111111111111111111111111111111111112",
  outputMint: "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v",
  amount: "1000000000",
  taker: "your_wallet"
})

→ 83.48 USDC, 22bps slippage, aggregator routing via Raydium
