AI2Fin (2Fin) Tax MCP Overview

This server exposes ai2fin.com's public tax tools as MCP tools: looking up a country's GST/VAT and income/company tax rates, computing GST/VAT on an amount, comparing tax across countries, and estimating income tax, company tax, or capital-gains tax for supported countries. It's stateless and computes only over public rate data, storing nothing; a separate authenticated MCP at app.ai2fin.com works on a user's real financial data behind OAuth. Every estimate is explicitly general information, not tax advice, and cites its source authority.
