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.

Hive Tax Observer
Observational tax-event tracking for crypto transactions. Real on-chain rails. Not tax advice. Not tax filing.
Hive does not provide tax advice or filing services. This is observational transaction data only. Consult a licensed tax professional for compliance decisions.
hive-mcp-tax-observer is a Model Context Protocol (MCP) server that classifies a settled on-chain transaction
into one of four observational kinds — sale, swap, income, or transfer — and surfaces the
cost-basis-relevant inputs (holder, asset, amount, counterparty, timestamp) your own basis tracker needs.
Real reads against Base mainnet, Ethereum mainnet, and Solana mainnet via public RPC.
We do not compute cost basis. We do not file taxes. We do not generate 1099s or any tax forms. Every response — including health, errors, and bulk responses — carries the observational disclaimer.
