What the publisher says

From the Stillos Swap repository's README, as published. We do not edit it. Read it on GitHub

stillos-swap-mcp

Non-custodial Solana swap routing for agents. Best-price execution via Jupiter, a flat 0.25% router fee (cheaper than Trojan/Photon/GMGN at 0.5–1%), and a free on-chain scam-check on every token you buy.

You keep custody. The tool returns an unsigned transaction — you sign it with your own key and broadcast. StillOS never touches your funds.

Tools

  • buildsolanaswap — { userPublicKey, inputMint, outputMint, amount } → { swapTransaction (base64, unsigned), expectedOut, route, routerFee, safety }. Sign and send the transaction yourself. When buying a non-stablecoin, safety carries an on-chain verdict (CLEAN / TRAP) based on live mint & freeze authority.
  • tokenscamcheck — { mint } → { verdict (CLEAN/RISK/UNKNOWN), mintAuthority, freezeAuthority, flags }. Established issuer tokens (USDC/USDT/SOL) are allowlisted. Read-only, no keys.

CLI

npx stillos-swap-mcp check <mint>
npx stillos-swap-mcp swap <yourPubkey> SOL USDC 0.5

Why the scam-check matters

A live mint authority means the dev can print unlimited supply and dilute you to zero. A live freeze authority means the dev can freeze your tokens so you can never sell. Both are the most common rug vectors on pump.fun. This checks them before you buy — free.

SOLANA_RPC env var overrides the default public RPC for the safety check.
