Integrates with Stripe for payment processing, webhook handling, and Pro tier subscription management.

1. Click on "Install Server".

2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.

3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Invoice Parser MCP extract the vendor, items, and total from invoice.pdf"

That's it! The server will respond to your query, and you can continue using it as needed.

Here is a step-by-step guide with screenshots.

server.py — MCP server (6 tools: parse_invoice, parse_receipt,
 extract_line_items, extract_totals, validate_invoice,
 export_to_csv)
auth.py — API key validation + usage tracking (SQLite)
x402.py — x402 micropayment verification (USDC on Base)
config.py — Environment variable loading
worker.js — Cloudflare Worker (remote proxy for MCP traffic)
data/keys.db — API key store (created at runtime)
data/usage.db — Monthly usage counters (created at runtime)
logs/ — Structured log files
tests/ — Unit tests (mock Vision API, no real documents needed)
