🚀 What It Does

TaxFormatter turns messy financial exports into structured, tax-ready data — for humans _and_ for AI agents.

Drop a CSV from Coinbase, a ZIP from Kraken, a .tar.gz from Binance, or a PDF statement from Chase, and get back a clean, normalized transaction set you can pipe into Koinly, TurboTax, CoinLedger, ZenLedger — or straight into your own software.

   Exchange CSV                        Clean, normalized
   Bank PDF              →             transactions (JSON / CSV)
   XLSX / ZIP / TAR.GZ                 + AI-generated insights

⚡ Quick Start

Run the web app

npm install
npm run dev

Open http://localhost:3000.

Try the API

curl -X POST https://api.taxformatter.com/v1/parse \
  -H "X-API-Key: tf_live_..." \
  -F "file=@coinbase.csv"

Use the MCP server with Claude Code

{
  "mcpServers": {
    "taxformatter": {
      "command": "npx",
      "args": ["@taxformatter/mcp-server"],
      "env": { "TAXFORMATTER_API_KEY": "tf_live_..." }
    }
  }
}

Install the Node SDK

npm install @taxformatter/sdk

import { TaxFormatter } from "@taxformatter/sdk";

const tf = new TaxFormatter({ apiKey: process.env.TF_API_KEY! });
const result = await tf.parse({ file: fs.createReadStream("./coinbase.csv") });

🧪 Testing

npm test              # Jest unit tests (160+ across API, MCP, keys, UI)
npm run test:e2e      # Playwright end-to-end tests
npm run typecheck     # TypeScript strict mode
npm run lint          # ESLint

🔒 Security Highlights

Stateless API processing — file content lives in Lambda RAM only, never written to disk
Zero payload logging — api_requests stores metadata only (hash, status, bytes, timing)
API keys SHA-256 hashed at rest, prefixed tf_live_ for easy identification
TLS 1.3 enforced everywhere
AES-256 encryption on all stored uploads
AWS WAF — DDoS shield, SQL injection, XSS mitigation
User-controlled retention — 1 year default, or delete-after-download
