What the publisher says

From the AI2Fin (2Fin) Tax MCP repository's README, as published. We do not edit it. Read it on GitHub

Tax MCP

The Model Context Protocol server behind the free tax tools at ai2fin.com/tools/compare — so assistants (Claude, ChatGPT, agents) can call them directly.

Stateless and no-auth. It computes over public rate data only and stores nothing. (This is separate from the authenticated app MCP at app.ai2fin.com/mcp, which works on your real financial data behind OAuth.)

Tools

The estimate tools answer only for countries with verified data and degrade to "not available" elsewhere. Every result carries a "general information, not tax advice" note and cites its source authority.

Data = single source

data/rates.json is produced by the website's gen:tax pipeline — the same source behind the calculator and comparison pages — so the MCP, the widgets and the pages never disagree. Don't hand-edit it.

Run / deploy

cd tax-mcp
npm install
npm run dev      # local: POST JSON-RPC to http://localhost:8787
npm run deploy   # to Cloudflare; then map a route e.g. taxmcp.ai2fin.com
npm run bundle   # writes dist/worker.js — a single paste-ready file for the
                 # Cloudflare dashboard editor when the CLI isn't available

Full deploy steps (dashboard copy-paste or CLI): DEPLOY.md.

Abuse protection is via the Cloudflare dashboard (rate limiting + WAF) — not auth.

Connect

Add the deployed URL as a custom MCP connector in Claude (Settings → Connectors) or ChatGPT (developer mode). A GET to the root returns server info; the MCP handshake is POST JSON-RPC (initialize → tools/list → tools/call). It pairs with the live comparison tool at ai2fin.com/tools/compare.

Quick check

curl -s https://taxmcp.ai2fin.com -X POST -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"compute_gst_vat","arguments":{"country":"AU","amount":100,"mode":"add"}}}'
