Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account mineloop99 for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Local MCP server that gives an AI assistant trading tools for Jupiter Ultra swaps, Polymarket CLOB v2 and Hyperliquid perpetuals, with fee and risk caps.

What you can do: Prepare and execute trades on Jupiter Ultra, Polymarket CLOB v2 and Hyperliquid perpetuals, with a dry-run preview mode and per-order notional, slippage and rate limits.
When to use it: For agent-driven trading on Solana and EVM venues where you want the assistant to prepare and place orders under hard caps. Not for read-only market data or casual use.
Requirements: Runs locally via npx (Node.js). Needs an operator EVM wallet key in OPERATOR_EVM_PRIVATE_KEY and an operator Solana wallet key in OPERATOR_SOLANA_SECRET_KEY. Optional settings include DRY_RUN, FILLGATE_VENUES, MAX_NOTIONAL_USD, MAX_SLIPPAGE_BPS, RATE_LIMIT_PER_MIN, HL_TESTNET, HL_BUILDER_ADDRESS, PM_BUILDER_CODE and JUP_REFERRAL_ACCOUNT. Network access to the venues.

Before you install

Requires private keys for operator wallets that can move real funds; use dedicated operator wallets, never a user's key. Trades can spend money and are irreversible. Keep DRY_RUN enabled until caps are verified, and note that unset builder or referral settings route fees to Fillgate's default account.
