Hive Tax Observer

Classifies settled on-chain transactions into four observational kinds (sale, swap, income, transfer) and surfaces the cost-basis-relevant inputs your basis tracker needs. Reads real data from Base, Ethereum, and Solana mainnet via public RPC. Exposes three MCP tools: tax.classify for single transactions, tax.bulk for up to 50 hashes at once, and tax.today for a free 24-hour rollup by event kind. Does not compute cost basis, file taxes, or generate forms. This is observational transaction data, not tax advice. Reach for it when you need to hook agent-to-agent payment streams into a basis tracker and want the classification layer handled for you.
