taxgst-vatfinancecalculatorsno-auth
A stateless, no-auth MCP server for public tax-rate lookups and estimates — GST/VAT, income tax, company tax, and capital-gains estimates across several countries — backed by the same data as ai2fin.com's tax comparison tools.
Quick Install
Automated & IDE SetupCopy the AI prompt to install this server into Claude Code, Cursor, or another agent — or use 1-click editor setup below.
One-click editor setup isn’t available for this listing yet — we don’t have a confirmed install command, and we’d rather show nothing than point your editor at the wrong package or host. Follow the project’s own setup instructions, linked above.
Manual Client & Custom JSON ConfigExpand JSON ▾
No confirmed setup config for this listing yet. We only publish a config block when the install details come from the project itself — its README, its docs, or a verified owner. We haven’t found those for AI2Fin (2Fin) Tax MCP, and we’d rather show nothing than a guess you’d paste into your client. Follow the project’s own setup instructions for the current steps.

Documentation Overview
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
| Tool | What it does |
|---|---|
tax_rate_lookup | A country's GST/VAT, income and company tax rates |
compute_gst_vat | Add or remove a country's GST/VAT on an amount |
compare_countries | Compare tax across countries — ai2fin.com/tools/compare as a callable |
income_tax_estimate | Income tax estimate over effective-dated brackets (AU, NZ) |
company_tax_estimate | Company tax estimate with small-business thresholds (AU, US, GB, IN, CA) |
cgt_estimate | Capital-gains tax estimate — losses, discount, marginal stacking (AU resident individuals) |
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
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.
