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.

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