Jupiter - 4 tools for swap quotes, liquidity pools, and trading data
Overview
Hosted MCP server exposing four Jupiter tools for swap quotes, liquidity pools and trading data, with no authentication required.
- What you can do
- Get swap quotes and related trading data through Jupiter endpoints
- Inspect liquidity pools and pool information
- Look up trading and market data for tokens
- Each tool maps one-to-one to a real Jupiter API endpoint, generated from the API specification
- When to use it
- Useful when an assistant needs on-chain Solana trading context — swap pricing, pool liquidity or market data — without building its own Jupiter integration. It is a hosted, no-auth endpoint, so it is quick to try in a desktop or web MCP client.
- Requirements
- A remote Streamable HTTP MCP endpoint; no packages, API key or environment variables are declared. The client must support remote MCP servers over streamable HTTP, and network access to the hosted endpoint is needed.
Installation
In SourceWeft
- Open Jupiter Mcp in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. 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.junct-bot%2Fjupiter-mcp/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.Other MCP clients
Add this to your client's mcpServers config.

Score
40% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
- Reached in the last 30 daysRequired25 pts
Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.
- Auth declaredRequired10 pts
Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
