jupiter_get_swap_quote

Use this when you need a swap quote on Solana. Returns the best route via Jupiter aggregator across all Solana DEXes with price impact and fee analysis. POST variant of jupiter_get_swap_quote -- same params passed as JSON body instead of query string. 1. inputToken: input token symbol and mint address 2. outputToken: output token symbol and mint address 3. inAmount: input amount in raw units 4. outAmount: expected output amount in raw units 5. priceImpact: price impact percentage (e.g. 0.12 = 0.12%) 6. minimumReceived: minimum output after slippage tolerance 7. route: array of DEX hops used (e.g. Raydium -> Orca) 8. priorityFee: recommended priority fee in lamports Example output: {"inputToken":{"symbol":"SOL","mint":"So111..."},"outputToken":{"symbol":"USDC","mint":"EPjF..."},"inAmount":"1000000000","outAmount":"67450000","priceImpact":0.05,"minimumReceived":"67112750","route":["Raydium V4"],"priorityFee":5000} Use this BEFORE executing any Solana token swap. Essential for getting the best price, understanding slippage, and choosing the optimal route. Do NOT use for EVM swaps -- use dex_get_swap_quote. Do NOT use for Solana fees only -- use solana_get_priority_fees. Do NOT use for pool liquidity analysis -- use solana_scan_pool_liquidity.

Jupiter Solana Swap Quote API — questions

Answers built from our own checks of this server.

What can Jupiter Solana Swap Quote API do?

It exposes 1 tools, read directly from the server on our last check. Among them: jupiter_get_swap_quote. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Jupiter Solana Swap Quote API working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 54 ms. The bar chart above shows every period we have measured.

The registry lists Jupiter Solana Swap Quote API as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Jupiter Solana Swap Quote API?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Jupiter Solana Swap Quote API need an API key?

No. Jupiter Solana Swap Quote API completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.

Is Jupiter Solana Swap Quote API open source?

Yes — it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
