Overview

AI-generated overview

Remote MCP endpoint that returns Solana swap quotes from the Jupiter aggregator, including route, price impact, slippage and priority fee, paid per call.

What you can do
Request a Solana swap quote for a token pair and raw amount, with optional slippage tolerance in basis points, via GET or POST variants of the same tool. Read back the expected output amount, minimum received after slippage, price impact, the DEX route hops used, and a recommended priority fee.
When to use it
Useful when an assistant needs to price or plan a Solana token swap: comparing expected output, checking price impact and slippage, or picking a route before a trade is executed elsewhere.
Requirements
A remote MCP client pointed at the hosted endpoint; nothing to install locally. Each call is paid in USDC on Base L2 through the x402 protocol, so an x402-capable client with a funded wallet is needed; no API key or signup.
Before you install
Every call costs money (USDC on Base) and is settled through a wallet, so spending limits and wallet key handling matter. The service is a third-party quote provider: token mints, amounts and slippage are sent to it, and quotes are informational, not executed trades. Payment goes through Coinbase CDP and PayAI facilitators.

Installation

In SourceWeft

  1. Open Jupiter Solana Swap Quote API in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via SSE. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.Br0ski777%2Fjupiter-quotes/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Add this to your client's mcpServers config.

README

Jupiter Solana Swap Quote API

[MCP Server] [x402] [License: MIT]

Solana swap quotes via Jupiter aggregator -- best route, price impact, slippage, priority fees included. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.

Quickstart -- MCP

Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):

json
{  "mcpServers": {    "jupiter-quotes": {      "url": "https://jupiter-quotes.api.klymax402.com/mcp"    }  }}

Quickstart -- HTTP (x402)

bash
curl "https://jupiter-quotes.api.klymax402.com/api/quote?inputMint=...&outputMint=...&amount=..."# -> 402 Payment Required, with an x402 payment challenge in the response body

Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.
