SOLANA_RPC_URL
HTTPS Solana RPC endpoint. Defaults to the public endpoint for the configured network; bring your own (Helius / Quicknode / Triton) for production.
METAPLEX_AGENT_NETWORK
Default cluster: mainnet or devnet. Defaults to mainnet; every tool also takes a per-call network.
REQUIRE_CONFIRM
Refuse to broadcast a mint or registration until the call is re-issued with confirm=true. Default true.
