Guides for MCP servers in Claude and Cursor

Practical guides: track billable hours, make an invoice PDF, log expenses and mileage, query Excel files, watch product prices, and what Pro adds. Every server runs locally over stdio, has a free tier that is useful on its own, and a Pro key that is a one-time payment.

• How to track billable hours inside Claude Code and Cursor
  Start a timer, log forgotten hours, get a weekly report and invoice lines without leaving the chat. Setup, tools and measured call counts.
• Create an invoice PDF from a chat message with an MCP server
  Say the invoice in one sentence and get a numbered A4 PDF with VAT lines. Worked example: 12 h at 90 EUR plus 300 setup, 23% VAT, 1697.40.
• Ask questions about an Excel or CSV file from Cursor or Claude
  Open xlsx and csv from the chat: describe the sheet, filter and group without code, add a computed column, convert. Handles messy header rows.
• Watch a product price with Claude and get told when it drops
  Check a shop price from the chat, keep a watch with history and a target, refresh on demand. Honest about bot walls and the missing background job.
• What the free tier includes and what Pro adds
  Exact free and Pro limits for all four MCP servers, the one-time price, how offline Ed25519 keys work, and the refund terms. No subscription.
• Log expenses and mileage in Claude, split VAT, rebill to an invoice
  Say a receipt in one line and get it logged, VAT-split and categorised. Worked example: 61.50 EUR at 23% VAT, Polish mileage, rebill without double tax.
