Environment

Name	Required	Notes
THREE_WS_BASE	No	Base URL of the three.ws API that serves the portfolio + trades endpoints. Override only when self-hosting or targeting a preview deployment.
THREE_WS_TIMEOUT_MS	No	Per-request timeout in milliseconds for the live three.ws API reads.
THREE_WS_SESSION	No	Your three.ws session token (the value of the `__Host-sid` cookie from a signed-in browser). Required for the account-scoped reads — get_portfolio_summary, get_portfolio_history, get_portfolio_asset — which return data for the agents YOU own. The public trade feed and on-chain balance reads do not need it. Treat like a password. Secret.
SOLANA_RPC_URL	No	Solana mainnet RPC endpoint used by get_wallet_balances and send_transfer. Defaults to https://api.mainnet-beta.solana.com — bring your own (Helius / Quicknode / Triton) for production traffic.
SOLANA_SECRET_KEY	Yes	Base58-encoded Solana secret key for the wallet that send_transfer signs from. REQUIRED for send_transfer (the only write tool); a per-call `secret` arg overrides it. Not needed for any read tool. Treat like cash. Secret.
MAX_SOL_PER_TX	No	Per-transaction spend cap in SOL for native SOL transfers via send_transfer. Bounds the blast radius of a leaked key or an injected argument.
RECIPIENT_ALLOWLIST	No	Optional comma-separated base58 pubkeys. When set, send_transfer refuses any recipient not in the list.
REQUIRE_CONFIRM	No	When on (default), send_transfer refuses until re-issued with confirm:true. Set 0/false to disable the gate.
