AI2Fin (2Fin) Tax MCP server

AI2Fin (2Fin) Tax is the official remote MCP server from ai2fin.com. It answers at https://taxmcp.ai2fin.com over streamable HTTP and asks you to sign in with your ai2fin.com account before it lists its tools, so your client opens a login the first time it connects. Our probes reached it 10 of 10 times since 4 September 2026; the last check, on 17 October 2026, got the sign-in challenge, so it is up.

Free public tax MCP: GST/VAT, income, company & capital-gains tax for 50+ countries, source-cited.

Description as the publisher wrote it.

What AI2Fin (2Fin) Tax needs before it works

A sign-in. The server refused to list its tools to an anonymous client and answered with an authentication challenge, which is how an MCP server protected by OAuth behaves. Add it with one of the setups below; the first connection opens a login for your ai2fin.com account, and the tools appear once you have approved it.
