shallowio.github.SajanMelcher/plumbline-mcp · Verify this server
Check on chain (Sui mainnet) whether an address holds the The Secret Journals license token. Holders unlock extra read-only education tools (golden_path_market_read). Non-holders keep every basic tool. Non-custodial: the desk never sees or holds keys and never moves funds; it returns quotes and UNSIGNED transactions only. Spot only, no leverage. Education only, not financial advice.
